Max positive camber and toe settings on 2nd Gen F-body

[Doug1]

I had the question below posed to me regarding a 2nd Gen Trans Am by a pretty knowledgable mechanic. It is beyond my expertise. Do one of you suspension experts have any thoughts on this?


"He is running some good Nittos and 17" x 9" wheels. I was hoping that you had some thought on what if any toe adjustment would be necessary after the max possible caster adjustment was made. The old school thought is that if one wants to feel more feedback in the steering wheel, you simply install as many shims as possible to the rear of your upper A arms by the way of removing them from the front and installing them onto the rear. Of course, there are limits to how many can be placed on the rear area as you still have to have the same caster setting for both sides while maintaining the proper camber setting. I saw that I can obtain more than the factory suggested +1 caster setting by installing these offset upper A arm shafts and may start using them on all of our builds: http://www.moog-suspension-parts.com/moog-k6146 Do you have any knowledge on how this will effect the toe setting? With the max positive caster setting (+4 or more degrees) do you have any knowledge or suggestions in what the toe would be?"
