tweaking the 325:
you're limited to expensive, very small gain things on the engine endeavour:
flywheel, airbox, exhaust.
suspension wise: that's dinan's forte and has always been so.
at the end of the day, one must realize that the 325 is not a dragster and the beauty is in the handling. once that set in for my small head, i relaxed. the car sure does handle so much better than anything else i've driven (except my e36m3).
ps. once you go to driver's school, the only thing you'll want to do are brakes or suspension anyway.
