Even though the mk3 isn't a car that everybody wants like the mk4. I still think you should work on the vehicles body a bit more and just throw some sick ass 8's in the back so you don't weigh the back end down like crazy. It's a sports car, they can be very nice sports cars. If you put a ton of weight in the back your gonna end up loosing handling, and the car isn't gonna have as much of a power to weight ratio and not only that, the ass end of that car is gonna be sagging bad and look like shit. 8's can get pretty mean
