Thanks! Michelin rubber is long gone... Nitto rubber is going up in flames though hahaha.

To be honest, it doesnt matter, the car is perfect right now.. comparing numbers is pointless as wel all know... Im just looking at my baseline to compare and concentrating more on the gain.

Please lets not get into a pissing fight about the GTM kit, we haven't seen 8psi third party results yet! not comparable!

This is the Stillen SC thread, theres a Stillen vs GTM thread somewhere in here. Discuss THAT there.
