[QUOTE=Dynomite;111767]Excellent point..I made some assumptions

That I am not sure about......normal Toe In is comparing distance between Front of tires (right and left tire) to distance between Rear of tires (right and left tire) on same axle.

It appears however since angles are used it is for the individual tire angle around vertical (Toe In) and the individual tire angle around longitudinal (Camber).

If you are correct (you prolly are) we end up with a Toe In Rear of 1/8 inch and Toe in Front of 1/16 inch (called a Racetrack Setup)

lbszr did you buy these adjustable control arms and install them on a ZR1? It appears to me these would fit on my 91' ZR1 as well as my 91' Corvette with L98

Thanks for figuring all that out, that makes my brain hurt.

I have not bought those control arms, just wish I would of when I had the front end apart. -2.5 Camber is all I can get, even with the offset bushings on the lower control arm. I believe the control arms would fit on both your 91's. It looks like any C4 88-96 would use the same one.

That confuses things with VBP measureing wheel to wheel, and GM's track specs measureing from the wheel to the centerline of the car for base settings. It looks like they both agree on the same measurement for the rear toe in, which is where I have mine set. The front toe in might give it a sluggish feeling on the turn in's, but make it stable on the straights. At 0.0 front toe in, mine is still good on the straights.
