S/C? Never. Technique Tuning Turbo Kit = Hell YES!
Rear fenders rolled already, but I can probably only fit a 15mm spacer in the rear max. I have 12mm all around already.
I agree with the M3 mirrors, but I can't convince myself to spend ~300-400 on M3 mirrors which won't gain me any performance :p
King Luis, I agree with you too.
