You have a clutch listed then at the bottom a built automatic, is this built automatic something other than a trans?? Don't know what it'll run but if it's an M6 and yer gonna run at the track alot then I'd suggest investing in a 9" rear.

Ditch the 10 bolt and 3.73s. Go with a 12 bolt or 9" and some 4.10s.

it gonna be a daily driver and will look into a 12bolt or 9 's when I get $$$. For the moment the 10 bolt will have to do.
