I'm real good friends with a dealership out here and they set up my alignment and couldn't nail it. It was like 1.14 degrees off at its max point... the pass tire would get closer to 0 but the drivers wouldn't. I dont notice any problems with tire wear, cept for my backs which is from similar shit to your sig :mexsmoke: I got the same drop u do, if u did spindles springs and flip kit. Watch your brackets in the back if u whale on your truck... check my pix out in postings on front spindles. Not sure if they make clips but i'd like em if they do cuz i'm goin lower. Help us out fellas!!!!fullthrottledan said:i got a 2000 sierra NBS with a 4/6 drop-chassistech(ugh. i know) and i am having problems getting the caster and camber during alignment. the stock pins only go so far and then start to roll back over. if anybody knows where i can purchase different pins or anything i can do, please let me know.
