Hey Paul, I have a ? for you. On my T3 I had a slight toe in difference in the rear, after a lot of re-adjusting of the pivot block I got it close to the same from side to side, I ended up having to put a .001 shim between the lower roll center holder and the bulkhead to make the sides equal.

Once everything was setup I tried my car on the garage floor(very slippery) and when rolling really slow the car looked like it was walking (or rocking) from side to side, like one side was trying to catch up to the other side and then vice versa. Yet when the car is on carpet or something with traction I don't see that oscilation effect. (not sure if the car did this prior to the shim) But now i'm wondering if the shim is enough that it has changed the wheel base of the car from side to side and this is the cause of the problem, or do all cars do this as a reflection of being 4 wheel drive and running rear toe in?

Also congrats on the Reedy win.

Thanks
