i just signed up to the forum, I recently bought a 2012 Rs5 and could not feel satisfied about it's performance, after getting slapped by my friends 2010 R8 V10. I researched everywhere for the kits and could not find reputable brands kits such as APR and Abt. I'm aware that...
Had a great time hanging out this morning with Scott (almostS50) and this is our first GTG since he had the APR Stage III Supercharger added. Enjoy!:

P.S. My car is ahem, not stock, but does not have a blower.
