GT3 caster settings
Whats the trick to get camber to 8? I'm at 9 and can't get anymore out of it, shims or no shims.
Is this when the strut needs to be turned? Or should I search this site for the answer that been posted before. Thx

You have 2 options:
1) Install the RSR-style adjustable thrust arms; GMG make a nice version

2) Press out the factory bushes in the bottom arm & install adjustable solid bushes. This is a good first step if you want to save money. The 2 products below are basically identical & I can't explain why there is such a massive price difference...

I've used all 3 of these products & for $100, I'd just go with the RSS pucks as an easy solution to allow castor adjustment.
The solid pucks & the RSR thrust arm are an awesome combination if you want to run slicks though.

How exactly is this done? Remove top bolts, then rotate clockwise/counterclockwise? Does the shock have to come out for the job?
My alignment settings are okay but too many shims and I am rubbing in front with just 235s. I'm tempted to rotate and shim less just to eliminate the rubbing.
Thanks.

The RSS for $100 is for 1 only, I assume, while the other brand = a set of 4..
If you have 9 degree caster, and does not have major rubbing, that is probably fine.. more stability.

More caster is preferable. Personally, I'll take a little rubbing in exchange for better performance.
Eventually the liners will be "rubbed in" and you won't hear it anymore.

Here is a picture of the right LCA mounted on the left side of the car and bolting the thrust arm to the forward off center hole. I'm running 7mm of shims per side.

You need to press out the 3 bolts and move them to the other holes in the mount - vice and socket as a press works fine.
You should be able to get stock caster and about -3degees per side with no shims after rotating the mounts.

Probably meant, you will need 4 of them for your car..
If it is $100 for a set of 4, that would be very cheap then.. I'd be really surprised.. !
I have the ones from Tarett Engineering, and they are $125 EACH!
