Get a light weight flywheel. UUC has a very good kit. B&B Tri flow, aa, or supersprint are also great. Dinan is the best, but too expensive. Short shifter, the UUC Evo is the best on the market. Jim C has a great power programmer. I have used the programmer and felt the difference. Good Luck to you. I have a few mods on my M3(Check my profile). I shaved about a half a second on my 0-100. 0-60 maybe a tenth or so. [driving2] [headbang]
