I have tein S techs in the car. I have had it aligned twice. The first time the shop that did it for me was awesome. He told me he got the front in spec. The rear he was out like .5 a degree and that was cause the tire was going to hit the fender. I am running 20's remind you. The second time it was just to fix what I messed up. I tore alot of the suspension out to get it powder coated. He did not need any special bolts or anything. he could have gotten the rear right on if I wanted to roll the fenders and even then we where not sure I would clear them. Now the way it sits I tuck alot of the rear tire and it would never work even with the fenders rolled.
