Whats the best performance upgrade for under $500 ??

[Cabra]

I have a 2002 330Ci

What do-it-yourself performance upgrades out there are most beneficial ?

And for under $500 ?

Just curious.

Thanks,

Swaybars hands down for handling. Get UUC or Racing Dynamics for about $350 per set, I think. Don't buy Dinan, as they sell rebadged and overpriced Eibachs.

Power wise, you won;t get much more than sound increase from the intake and exhaust, so you can buy those later on.

And bring to the track or AutoX to really have fun with your car. Do it once and you'll be hooked for life - trust me on this one.

differential (poor man's supercharger), by shortening the final drive you will increase your acceleration, if you look you can find a differential with the gearing you want at a junk yard for no more than 400
