Just brought myself a 2006 Mazda6 MPS in grey.... with plans to building a race car. It has a FULL EXHAUST FITTED WITH BC COILOVERS SHOCKS, CP-e CAI, FORGE BPV, SLOTTED BRAKES, DEEP DISH WHEELS (19'S) and luxury pack. But after driving it I feel it's to nice a car to gut out and bolt in a Roll Cage.
Anyhow I hope I can get some good advice on performance upgrades and modifications to do to the 6.
