Without spending $5k+ on forced induction, what should my next step be, mod wise? Right now I have an ECIS intake, Dinan Stage 2 software, 18" BBS RK's, tint, my AVR E46 M3 spoiler is on the way, I'm lowering the car within the next 2 weeks, and I'm waiting for the 3rd gen AA exhaust to come out. What's next? Appearance wise I'm pretty happy right now, I'm getting m3 side mouldings/door handles painted when i get the airdam put on, and I'll probably get some eyelids too. At this point, I'm looking for some more straight-line performance. I've been thinking about a lightweight flywheel when I replace my clutch. What else can I do when I have that work done? M3 cams? Any suggestions would be greatly appreciated.
