Performance Mods (Gasp)

I searched only found a thread on Vorsteiner but I was wondering if there are any recommended standard (and reasonably priced) performance mods for the e92.

Depending on the type modification there are many vendors to choose from. Do you want to enhance the exterior with carbon pieces, add a new exhaust, rims, supercharger, etc. It is a question of preference and of course budget.

There are other forums for the M3 enthusiast which covers each area specifically. Search is your friend.
