07MCSS Performance Upgrades
I am a newb so excuse me if I ask some ignorant questions. First off I see alot of you guys talking about a "Built Tran" what does this actually mean and how much does it usually cost (I have replaced transmission twice in this car and its only inevitable that it will go out again). Other Mods I want and would like suggestions: CAI, Exhaust, Tran Cooler, Suspension, Shift Kit, etc...
