Re: Alignment specs for drag racing

All I do is jack the front up an inch and a half or so, and set it to stock spec (or as close as they can get) It is on the street so seldom any more that getting a ' track' attitude for top end control is the priority.

Re: Alignment specs for drag racing

I typically have them jack it up 1.5" then get as much caster as possible, 0 to .5 degrees of camber and 1/8 total tow...

Re: Alignment specs for drag racing

Dead at work today so we put it on our new hunter alignment rack. Camber is 0, caster 3.4 and toe is .09.
Had to take back shims completly out to get caster to rise, but 3.5 seemed the most we could get and keep some camber adjustment. Ordered a Afco & QA1 catologs. I understand the front spring requirements, but how do you determine the rear spring rate ? Thanks Cooter
