I'm considering the AA Twin Screw for my M3.I have the AA exhaust and other Mods including JTD underpanel with Brake ducts, Adjustable coil-overs and X-brace. Obviously my AA CAI and chip will be replaced.
I will be adding a light-weight fly wheel. What clutch should i be looking at and will the brakes need to upgraded.

I do about 6 DE's per year...2 on a short technical track, 2 at Portland and 2 at Seattle....i will probably up my DE's over the next few years
