oh and believe me a nicely tuned 335 will take this car too spending 1/10th the money of the 3500
MTM sells overprice parts..once GIAC, REVO,APR start will probably offer the same performance for about 700$-1000$
I think that the S4 will kill the 135-335
They will be easier to mod also(pulley,boost)
(RS4 MTM supercharger is 20K while the VF is about 8K$)
I would buy an m3 over an S4 anyday of the week
