I could/can get -2.5 in the front or rear of my car if I wanted, stock bolts, coilovers and camber plates.. I ran -2.2 all the way around when I was lower..
I've helped every alignment tech do every alignment on my car to this point... just letting someone "go" on my rig isn't in the cards... That and it's a 2 person job to get it right BECAUSE there is so much adjustment..
I literally hold the wheel and the tech tightens the bolts till we get it right.. (@-0.9 now all the way around after raising the car up and not NEEDING it)
Something is either WRONG, or the tech wasn't up to par... either way, I would have been there had it been my car.. (jus sayin)
