Gen IV Alignment Specs

[cobra_maker]

In answer to calls about the alignment specs for our GEN IV Cobra here they are:
Front Camber is 1/2 degree negative (-0.5)
Front Caster is 1/2 degree negative (-0.5)
Toe In is 1/8" inward
For the Rear 1/2 degree negative (-0.5)
Toe in - zero (0)

For earlier Gen III cars the Corvette front end was 4 to 6 degrees negative Caster and for the Mustang II front ends it was negative 2 degrees. The Camber and Toe In was the same as the newer car.
Your alignment shop can input these specs and set up your car without resorting to Corvette, Ford or other manufacturers data sheets.

Took my 2005 Gen IV to an alignment shop today and handed them the specs I copied off this thread. They were not able to remove any more than 1 degree of camber from -3 to -2 while the specs call for -.5, the toe in was out also and they zeroed it out. The drive before was very darty on the highway, this took most of that out but I'm still concerned about tire wear on the insides. If the upper arms were a bit longer the camber could be reduced.
Any experiences?

I think your front caster should be positive.

Every other car I know is generally positive caster, and negative camber.

I agree or at least nearer to the -.5 in the specs. The shop I went to is very reliable and they said they couldn't bring it down to less than -2.0. this is because the upper arms are too long pulling the top of the wheel in.
I was hoping someone with a Gen IV might have had theirs aligned and could measure their arms length. I e mailed Tom but have not heard from him.

Caster should be positive if you want stability and handling.

Same principle as a motorcycle front wheel.
