im still reading into the SCCA classes and where which cars fit. I might start in the touring class 2 with an M3. I've always wanted a type-r and my choice is going to be difficult. I would like to lighten my DSM and run that but it would probaly break down putting it on the trailer :-) DSM's aren't very reliable....I'm going on three months with no problems and I'm just waiting for something to happen...
