quite the list, if I had this kind of money:
in the "performance" category, I would be inclined to spend less money on exhaust and intake and put the money into suspension / wheel / tire
M3 front control arms
M3 rear subframe bushings or powerflex inserts
Camber plates
Apex ARC-8 or EC-7 (lighter unsprung weight) for summer
Hankook Rs-3 for summer
...and no way I'd have an automatic
good luck, enjoy this
