I am in the market for an LT1 Camaro, I am going to get regardless of the problems like the transmission and rear end, but I want to know really how much can the rear end handle? I will be modding it, first exhaust and intake, then probably heads and cam. I will probably get an A4 which I know is easier on the rear end. But I do drive the car very hard. What I guess I'm really asking is should I just save up the money for a 12 bolt for piece of mind that it will probably never break?
