Hello everyone, I am new to the forum, I currently own an E36 M3, and I fell in love with Audi S4. I was wondering what kind of mods would make my car a total sleeper, and on top of that, make sure that it handles as well as the M3. any feedback is greatly appreciated. I also want to beat out my friends 2002 WRX in this car that I am going to be getting soon enough once the M3 is all modded up the way I want to.

Mods for your project:
Chip - GIAC or APR
Exhaust - APR, AWE, Borla, Milltek, or UUC
Intake - AWE
DV's - Bailey or Forge
DP's - APR, AWE, or LaBree/Tantrumwerks
Coilovers - H&R, FK, or Stasis

Or... for maximum thrust: RS4 KO4 kit - APR or AWE
