custom carbon fiber company... I have contacted 2-3 that might do the job for me in 6-12 months... Def the last thing I am getting around to... if you haven't rebuilt your gears, fueling, cams ect... that would make a HUGEEEEE change from most stage 3 a6's ppl have (stage 3+ clutch, or torque converter). OR changing your car from 5 speed to 6 with getting the gears set for tiptronic or manual.
