Hey Shawn, I was wondering about teh DA supercharger u have. I was wondering if it is worth it. I really don't NEED it per say, but I wanted to have the power just in case. I was also wondering what other upgrade the SC would call for IE strut Brace, shocks, spirngs and teh like. Oh yeah, I am getting hamman HM3 17' wheels and i was wondering what do u think i coul dget for my stock z3 wheels and tires, the tires are in OK shape.
