Removing Lotus Elise (111R) Steering Arm Shims

Why do this? To gain negative camber for better steering response, of course. Some LotusTalk threads I reviewed prior were these:

Some tools I used to accomplish this:
· 3/8 socket wrench
· 3/8 socket handle
· 3/8 torque wrench
· 8mm HEX 3/8 socket
The B jack point is used to lift the side of the car being worked on with a low profile jack- I (and others) would encourage the use of jack stands. After the jack was just starting to lift the car, I broke the lug nuts all loose before jacking the rest of the way and removing the lug nuts and wheel:
In the picture below you can see the steering arm and the HEX bolts that will need to be removed to remove the shim(s).
By turning the steering wheel to full lock left/right the front and rear HEX bolts are EASILY accessed:
On some Elise/Exige models the front can be loosened and only the rear HEX bolt removed but my shims had to be difficult- I had to remove both bolts. The key was removing one bolt at a time, getting that end of the shim out of the way, applying blue thread lock to the bolt, putting the bolt back in and loosely tightening, and then doing the same for the other bolt to remove the shim. If the steering arm gets out of line it is easily moved by hand to realign and start bolt. Every car is different, mine only had one shim on each side but different cars can have different sized shims and one or many that can vary side to side. The ABS wiring holder also acts as a shim, I left mine installed but some remove this and zip tie it out of the way:
With shim removed it is time to torque the HEX bolts to spec, in my case with the 10.9 grade bolts it was 68 Nm or ~50 ft/lbs:
