Robert, I believe you got the other spec's out of the Vette Brakes Catolog, Mikeee, whatever set up you decide on, make sure the shop you go to has an up to date computor 4 head alignment machine, with a print out, have them print out what the alignment was before and after the alignment, some shops stick to stock spec's and might have you sign a release if you go with custom spec's, that way you can't come back and say it's "not right" if you go custom you might have to have it done more than one time to get it where you like it, I aligned mine in the driveway with a Longacre Caster camber gauge, a tape and level, works for me. Good luck anips2009-06-11 19:59:42
