Gentex Series 8 Frameless Auto-Dimming Mirror with Homelink P/N 50-GENK80A (installation and user manual HERE) purchased and installed along with my faithful Valentine 1 radar detector (manual HERE).
[EDIT] NEW V1 Gen2 replaced prior V1 (Owners Manual, Quick Start Guide, Programming Guide, Troubleshooting, How To Upgrade)
The mirror is a little wider but sits closer to the headliner so visibility is about the same. Some opt to remove the existing mirror mount and install a new one, but I found the existing mirror mount worked somewhat- not perfect but I really did not want to risk damaging the $3500 windshield I later discovered that although it appeared to be secure it really was not making great contact anywhere but at the lower end of the mount and the mirror did not slide far enough on to the OE mount to really seat.....it did vibrate a little after some time in the heat/sun so I ordered Dorman 76864 Rear View Mirror Bracket Assortment, 3 Piece and Versachem 11109 Rear View Mirror Adhesive from Amazon. OE mount removed and new mount installed without issue- lots of YouTube videos out there but this one is a good one - I used this technique coupled with vice grip pliers on the mount (not touching the glass), proceed at your own risk as there are many horror stories out there.
Pics below illustrate the process to access the passenger footwell fusebox and wire the 12v +power and -ground. All wiring came from the manufacturer with each product and included fuses. I did have to source an Add-a-circuit Fuse TAP Adapter Mini ATM APM Blade Fuse Holder to tap into an empty accessory socket in the fuse box, this also required trimming the ridge around the fuses so that the tap would fully seat in the fuse socket. For a ground I just loosened one of the Torx bolts holding the fuse box to the mounting frame, inserted both ground terminals, and retightened. The a-pillar trim can be removed by pulling at the top and then straight out. The foot well panel can be carefully pulled out after removing 3 screws (Look like Phillips head but are actually Pozi) at the base under the floor mat, one screw at the upper right, and another screw on the upper left under a plastic cover (this requires removing a plastic push pin rivet on top and two Torx bolts on driver/passenger side and pulling up/sliding the cover towards the firewall to remove)- hopefully you don't need to replace a fuse in some remote location because this is not a quick process. Wiring can be tucked under headliner and run over and down the a-pillar to the fusebox.
This forum thread was a big help

Lloyd Luxe Floor Mats from Auto Anything purchased so that the factory 4C floor mats could be saved for posterity.

After a few weeks I see myself owning this car for a while (famous last words but only the second vehicle I have purchased an extended warranty for). Mopar/Alfa Romeo offers a Maxcare warranty option up to 8 years/125k miles from the in-service date. I purchased the Mopar warranty on our Jeep from Clay Robbins at Robbins Motors and he beat everyone else. If you need a Mopar warranty inquire with Clay Robbins via email, he is the owner at Robbins Motors (formerly GM/VP at Zeller Motors) and was very responsive to emails and quick to process our application and deliver the warranty.

POWERFLEX Lower Engine Mount Bushing Insert (P/N PF1-1020) ordered from EuroCompulsion....installation instructions HERE and HERE- note the factory manual shows torque plus angle for what I guess are NEW stretch bolts, EC has "NOTES: Torque Specs for Both Lower Engine Mount Bolts are 80NM/60FTLBS" on their store page for what I guess are the existing bolts, torque with no additional angle. I chose the Yellow Street Durometer (75A), nothing super hardcore like replacing ALL of the mounts in the Lotus with solid poly.....felt great but made ALL rattle, including the passengers- YMMV I'm just trying to limit 'some' of the engine slop.
Forum thread HERE. Video that shows OE engine mount removal HERE.
I just removed the bottom panel (no need to remove the diffuser) and then the smaller panel covering the mount- T30 for all bolts. There is a heat shield on the mount, slide clip off and remove. I was able to get a breaker bar on the 15/16 bolt to break loose, then used 13/16 and 15/16 Gearwrenches to remove the bolt/nut- you can pull the mount down and push the exhaust up to get the bolt out. An E18 (External Torx) is used to loosen/remove the other bolt. Mount removed and rubber cleaned up where mold lines are at, at large end insert small black bushing into bolt hole and yellow bushing into mount voids. Reinstall mount (don't forget the metal washer/spacer on top) and torque to spec- I was able to line the motor/trans up with the mount to insert the bolt by hand, reinstall heat shield, reinstall panels- DONE. I did have the thread wear in the large end where the mount moves against the bolt, the small black bushing should fix that.
Went for a ride in the N. GA mountains and did not notice any additional NVH but shifts were more positive and throttle response seemed a bit better without the play this mount insert eliminated- cheap mod, should be at the top of the list.

Some pics from 2018 August mountain drives in North GA/SC/NC/TN.

Alfa Romeo did not give us an AGM battery so I decided to try the Odyssey battery I had from my last car see if it would work. An Odyssey PC1200MJT from Amazon (Battery Mart) installed using a hold down strap from Poly Performance (SKU WCB-HDAS-METAL - West Coast Battery P/N HDS-1200/1700) as recommended by Odyssey for this application....I also elected to add a piece of foam weatherstrip to the inside top of the mount. This was NOT plug and play but involved some additional modifications to the hold down strap. I had already modified the hold down strap for the last car (detailed HERE) but had to grind a little more to get it to fit the Alfa tray. I also fabricated an aluminum clamp (which I may paint black later) to hold down the rubber cover since I had to eliminate the OE retention strap (rolled up and tucked between battery and mount). Saves a little weight but that was not the main reason for upgrading- I don't have to worry as much with an AGM battery.

OE vs PC1200:

PC1200:
[EDIT] After 6 years, the PC1200 was losing a little bit between drives so I bought a new Odyssey ODP-AGM47 H5 L2 (Group 47 which is same size as OE) from FCP Euro with their Lifetime Replacement Guarantee. The 4C does not get driven much and the PC1200 had been brought back to life a few dozen times with the Odyssey Ultimizer.

EuroCompulsion V1 Intake that works with the OE airbox ordered. Did not purchase as a kit but sourced the EC silicone/Kevtek hose/clamps from a forum user (they didn't have the filter) and then ordered the Sprint air filter from EuroCompulsion, all new at a ~30% savings versus just ordering the kit.
Analysis HERE shows why Sprint filters are better than the rest (PDF version HERE).
[NOTE] If you decide to go to the V2 Intake after the V1, EuroCompulsion offers an upgrade HERE. I never installed the V1 but did order this upgrade so with your V1 hose and clamps and the upgrade filter and clamps you have a EuroCompulsion V2 Intake.
V1 Installation instructions HERE, V2 Installation instructions HERE, Tech document HERE, forum V1 discussion HERE, forum V2 discussion HERE.
Air filter cleaning instructions HERE, air filter cleaning kit HERE.
Personally, I don't find the V2 that loud and even my wife was used to it after one drive......but this is very subjective. I do wish that EC had included some type of bracket for the current filter like the one they had on the original V2 Sprint filter. The filter can be tucked towards the front to avoid contact with some sharp edges but it CAN flop around a bit- some have used zip ties to keep it in place. I may have to engineer some type of bracket that utilizes the old mounting points for the OE filter box. Also some forum users have complained about the "Phillips" screw that attaches the intake funnel to the airbox, how it is tight and feels stripped.....well, that's because it is not a Phillips screw but a Pozidriv screw- but I didn't know about these either until Lotus ownership. This article explains the difference.
This thread details a forum user's experience with an alternate/replacement air filter. 4C Forum's moehler found, as myself and many others did, that the provided EC air filter poses some challenges trying to wrangle on to the MAF sensor and found a replacement filter from Green Filter, P/N 2303. I found that P/N 2895 is the same filter but white without the green color at reduced cost, so I bought one to try. The cleaning/oil kits were color specific, although that might not be the case now with supply chain challenges, so be sure to order the correct one if available. The cleaning kit with clear oil specific to my filter is P/N 2800, I'll probably just get the readily available Green Filter P/N 2000 Green High Performance Air Filter Recharge Oil and Cleaner Kit since the filter will not be visible. Cleaning Instructions HERE, archived HERE.
[EDIT] I have had Green Filters on order through Vivid Racing since March 2021, no ETA in sight, collected my $$$ in March and several missed target ship dates later no delivery or follow ups......even after I made phone calls and sent emails requesting updates from both companies- STILL WAITING. Vivid Racing started responding again to my periodic requests for updates but was unable to get in touch with their Green Filter rep for updates.
FINALLY in November 2021 after submitting a BBB complaint and communicating via FB, I have a ship date this week.....why make this so hard for customers? All we require is some communication.

Time to upgrade the intercooler hoses with this, EuroCompulsion Complete Intercooler Hose Kit. Why upgrade the intercooler hoses? Your answer is HERE. Docron's write-up on the upper intercooler hose he installed HERE. Lower intercooler hose intro from EC with another Docron writeup starting post 23 HERE.
Alfa9 Supply also carries a hose kit.
All clamps were able to be removed with the screwdriver prying method except the middle hose/front clamp- that one required a Dremel and cutoff wheel. I tried for an hour to use a screwdriver/wire snips and no go, 2 minutes with a Dremel and off...but be careful, you don't want to cut anything but the clamp, I was able to cut just through the clamp most of the way and break the clamp off with a screwdriver, no hose damage.
I also discovered that some of the OE hoses are notched so they only go on one way during assembly. Several ways to approach this (or not at all) but for my OCD the only options were to Dremel the plastic tab off or cut a notch in the new hoses so that they would go all the way to the stop. I elected to snip notches in the new hoses so that my path back to stock was open.
Hint: Sex lube IS the stuff to get these new hoses to slide right into place, I laughed when I read the forum advice but it is true....a little goes a long way.

After reading THIS THREAD (EC comment HERE), I decided to proactively order the Gale Motor Sports Turbo to Intercooler Pipe- Installation Instructions HERE (install pics below).
I installed this when I installed the new lower IC hose above, I don't really notice any additional noise and the OE turbo to IC pipe (turbo muffler) was not broken (yet) at ~8k mostly street miles.

4C Lift Kit from InoKinetic (aka Sector111) installed. The addition of these parts reinforces the rear diffuser/undertray so that the car can be lifted from the center.
Installation/Use instructions HERE, Forum threads HERE and HERE.
I use a hockey puck with my floor jack to somewhat cushion the diffuser.

I really missed Android Auto and a backup camera so Alpine to the rescue:
Alpine Halo9 iLX-F309 Audio/Video Receiver (Owners Manual and Installation Manual).
I had originally ordered the Alpine rear camera but decided to stay with something close to OE. I discovered on this thread that the Fiat Grande Punto camera works on our car, it replaces the tag light on one side and I ordered one of many from Amazon, ASIN B078X6TYZ2.
Many good threads on rear cameras and installation on the 4C forum:

Wiring run help

Joying Installation with Rear Camera

Installation- Wiring, easy since I had the OE Alpine radio, I just had to move two wires that were missing in the OE plug from the new plug. Small pick used to release/remove wire pins and then inserted in correct position in the plug already in the car. Other than this and the camera wiring I will need to do at a future date, plug and play. I knew I would need to fabricate a way to support the radio since it is REALLY designed to bolt to the chassis mounts used in other cars. I just kept the existing sleeve for the OE radio in place and moved the rear locating PIN to a custom bracket that slides into place on the new radio. Only caveat with my custom bracket is that it required installation from behind/below after the radio was partially inserted into the sleeve, this required some yoga/contortions in the passenger side footwell. After installation it was SOLID. One trick to note is that the display should be mounted before pushing the radio all the way back, no way to assemble completely before the chassis is inserted and no great way to assemble with it inserted all the way. The chassis allows for a closer screen mounting position to the dash but this will not work, just leave it as it comes. I also purchased a MicroBypass Parking Brake Override Bypass for Alpine (instructions HERE) so that I could access functions without tapping into the parking brake wiring and having to use the parking brake, this gets you most of the way there but I opted not to install the GPS antenna (my phone acts as the GPS antenna when using Android Auto and this Alpine does not have NAV) and I found you cannot set the clock without the GPS signal (WTH Alpine?)- no worries since we have a clock on our display. After installing this head unit I was pleased but left scratching my head as to why some things were engineered the way they were. The display is large and close to the right stalk and key but I don't mind making small compromises as long as everything still works. The OE speakers sound significantly better with the new head unit and Android Auto works as well as it did in the GT350 with factory hardware. Rear Camera on the way.......

[UPDATE] I saw how an installer had installed this head unit in another forum member's car and decided to try adjusting the display depth/height/angle to replicate that. Depth is all the way in, as it comes from the factory, height is adjusted one hole up from the bottom, and the angle adjustment screws are just left out- it seems tight enough without them...and with them the angles won't work as it makes contact with the top or bottom of the dash, the issue I had when installing the first time....I like it better, we'll see how it works out. If it doesn't I'll just slot the angle adjustment holes...

Fall (October 2018) - Quick run up to Dahlonega for brunch and to drive the 60>180>129 loop with a friend, landmark rock pile roped off due to construction....... Story of the rock pile and Trahlyta can be found HERE, HERE, and HERE.

(November 2018) - Quick run up to Joe's BBQ in McCaysville for lunch and to drive the 60>180>129 loop. Joe's is now closed for business

Aluminum AC Knob covers from AutoPlus Japan purchased as part of a forum group buy (THANKS Evoralution for organizing ), forum thread HERE.

Time for an extra set of wheels. I went to look at a set of OZ wheels another 4C owner was selling and saw his new TITAN 7 T-S5 wheels (weights HERE).....game over. I reached out to Matt at Alfa9 Supply and he promptly responded with several different options and quotes, I decided to go with machine black (Front P/N Original-TS501880034509858MB, New/Current TS501880030598058MB, Rear P/N TS501990025509858MB). As an update, the original front offset was +34, at some point Titan7 updated this to +30 and no longer makes the +34- note the new part number. Very informative review from buildjournal HERE. I also decided to upgrade the lug bolts to Titanium, also from Alfa9. Of course I am keeping the OE wheels so I needed new TPMS sensors, ITM Set of (4) 433mhz TPMS Tire Pressure Sensors 2015-2019 Alfa Romeo 4C Replacement sourced from Amazon- after mounting wheels they showed up immediately, no programming required as stated by the seller.

For tires, I decided on Firestone Firehawk Indy 500 (TireRack test HERE, videos HERE and HERE) in 225/40/18 and 255/35/19 (TireSize Calculator HERE).
Pictures below are of a dirty car but hopefully show how good these wheels look.

Attended a Tail of the Dragon/Cherohala Skyway run with the local Alfa group, and stopped by Bell Mountain on the way.
The first time we went to Bell Mountain was in my Jeep back in 2013, before it was paved you HAD to have a 4x4 to drive to the top: some video HERE starting at about 11:30 and HERE.

Fiamm air horns (P/N 66020 2 Projector Riviera) installed to replace weak OE horn, sourced from Amazon.
Installation Instructions, Installation Video, Data Sheet, and Fiamm Sound File (mp3)
To avoid hacking/cutting the factory wiring harness I sourced Metra 72-5600 speaker harnesses from Amazon that happen to also work with our horn plug- you only need one but since they only come in a set you'll have spares or some to share. You may need different spade connectors for the horn and I actually had to sand down the end of the plug a bit so it would click into place, YMMV. Thanks to forum member Knievel for the info.
To start you'll need to get the car in the air, at least the driver side front corner, and remove that wheel. The front part of the fender liner is held in place by a variety of fasteners so you'll need a Phillips screwdriver, 10mm Gearwrench/socket wrench, T30 socket/wrench, and 5mm Hex socket/wrench- don't forget the two screws on the bottom.
I made a new bracket for the horns out of flat aluminum bar stock, although you could also drill a hole in the OE horn bracket and re-use that. There was an existing hole and great location for the horn compressor to mount. Since these horns were from a prior car, I went ahead and replaced the tubing. I did replace the 10A fuse with a 20A fuse, the 10A fuse didn't blow right away but after a few uses.

I had been thinking about Quadrifoglio emblems for a while but could not swallow the price tag for the OE Giulia/Stelvio parts that really would not fit the 4C fender contours 100%.
EuroCompulsion carries the Novitec emblems in both Alutex (White CF) and Carbon Fiber. Decisions, decisions.....I ordered one of each to see how they look and decide which one to use.
The Quadrifoglio explained, Petrolicious article HERE.
And then there is also the Scuderia Biscione Shield available from forum member Rlbarca/Studio Scuzimi
The Scuderia Biscione history/meaning can be found HERE.

Attended our first Mitty race at Road Atlanta, the featured marque this year was Alfa Romeo.
Official Race Schedule (final revision) HERE.

When I purchased the 4C it was evident that someone had tried to use the horn by pressing on the center slightly denting the airbag emblem....not noticed by anyone but my OCD self. The only way to correct was to buy a new airbag or source a new emblem. I found the emblem I wanted but unfortunately it only came as part of a set from Madness AutoWorks, so I just bit the bullet and ordered the set.....maybe I'll use the other pieces at some point in the future, but for now just the steering wheel emblem- carbon fiber with yellow Alfa Romeo logo.
E6000 High Viscosity Adhesive was what I chose to use since it has worked well in the past. I used blue painters masking tape to make a grid around the OE emblem, using the lines of the Milan cross to mark the masking tape and make sure the horizontal and vertical were straight. Cleaned both surfaces with brake cleaner and put a small dab of E6000 in the new emblem, placing it over the old emblem and getting it centered/straight- held in place for a few minutes and then left to set, periodically checking (E6000 can run if too much is used, viscosity is low, temps are high, etc.- this would make a mess in the seats and floor mats so it might be a good idea to place some paper under the steering wheel just in case....). E6000 takes 24 hours to cure and 72 hours for max strength.
New emblem looks great, OCD issue solved!
Also, I did look up a few pics of deployed airbags to make sure the function would not be affected: HERE, HERE, and HERE......it appears the airbag center stays attached to the steering wheel.

Replaced all non-LED bulbs with LED. Started off with name-brand Sylvania ZEVO bulbs- THEY DO NOT WORK!
Next tried AUXITO from Amazon after reading the good reviews, so far so good and BRIGHT.
Docron's 4C Forum thread was helpful.

Unfortunately, not error free for Alfa. I'll just ignore the "Check Reverse Lights" message at startup.

With the COVID19 outbreak and subsequent shelter-at-home orders, AROC decided to do a Saturday Zoom Room for Alfa Romeo Owner's Club members (Thanks David Hammond, President AROC Detroit Chapter, for organizing!).
This first meeting I attended was where Ralph Gilles (FCA Head of Global Design) spoke about his Alfa GTVR and some other Alfas he owns/has owned. I met Ralph briefly at the Viper Plant closing in Detroit, really nice car guy that gets it. AROC YouTube video HERE.
The second meeting was Bruce Kopitz showing his Stage 3 4C upgrade path/modifications and explaining why they were chosen. AROC YouTube video HERE.

CHECK Your TCT Selector Hydraulic Oil Level: 4C Forum: TCT Selector Hydraulic Oil Level Check
The twin clutch tranmission in our 4C has a hydraulic gear selector that has its own fluid reservoir, located on driver side under the intake hose. You really need Alfa OBD to depressurize the circuit but may be able to get an idea by letting the car sit a while after opening the door to release the engine cover- that noise you hear when opening the door is the TCT selector hydraulic system pressurizing, this will lower the amount of fluid in the reservoir. As it depressurizes the fluid is returned to the reservoir.
If you use a flashlight from above and behind you can establish where the fluid level is. Important to shake the car a little to see where the top of the fluid is, the reservoir can be stained inside and the level might appear higher than it actually is as a result.
The 4C Cloud has an early version of the workshop manual process HERE (specifies TUTELA CS SPEED Contractual Technical Reference No.F005.F98 oil), my 2017 workshop manual process HERE is slightly different (specifies MOPAR P/N 68092638AB oil). A few suppliers meet the CS SPEED CTRN F005.F98 spec such as Petronas and Ravenol which can be sourced at Amazon.
Pics below illustrate process/location and levels at varying time frames from right after door was opened to hours later.....you can see the level changes and how the level can be misleading due to internal staining of the reservoir.

2020 Polar Bear Run with the Alfa Romeo Owners Club and the GA Triumph Association (and others). There was a bit of ice and gravel out as we got into the North GA mountains, temps started out in the high teens/low twenties. Lots of different cars, Jack in the Fiat club posted a video of the rest stop enroute HERE.
We completed the run with lunch at The Black Sheep in Blue Ridge and then headed to Grumpy Old Men Brewing before heading home.

August 2021 drive with the Alfa Romeo Owners Club. Started at Carroll's BBQ in Blue Ridge, GA, then on to McCaysville, then to Mercier Orchard, and back to Pasta Market in Blue Ridge. Great food, great Alfas, great people, great time!
And now I think we have to have a Giulia Quadrifoglio (with Sparco seats)

Attended the October 2021 Chattanooga Motorcar Festival with the Alfa Romeo Owners Club (Atlanta Chapter)
Based on the show load-in maps for Fri/Sat it seems the Alfa Romeo Club has one of the larger clubs.
Preview of the festival from Corky Coker is HERE, video ad for 2021 has 1st festival highlights HERE. We met Corky Coker and Wayne Carini the first day we were there.

Time to do the belt service, QuickJacks worked well for this since I did NOT remove any bodywork, all was done through wheel well, from under the car, or from the top- no issues. I can see where removing the body work would improve access, just not enough ROI for me.
I also did NOT loosen the cam pulley bolts, water pump can be removed and installed just fine as can the timing belt.
I will say I found differences between the pictures/instructions and tool sizes required when using both the AlfaWorkShop guide AND the factory manual but small things easily figured out. If you do not have a Ribe bit set, you might need one as a lot of the "Torx" bolts are really Ribe. Northern Tool was the only local place I found that carries a set which I purchased earlier for some other 4C project. This is a good website that shows the difference between Torx, Torx Plus, and Ribe.
Like others have found, the passenger side motor mount was done, but I caught it before it leaked. I ordered new mounts from Alfa Work Shop, the driver (gearbox P/N 50526604) and passenger (engine P/N 51888093) upper side mounts, but only replaced the engine mount for now.
All of the forum and vendor resources I used are listed HERE
