Spec so far.
Colour sorted, additional paintwork, leather tbc, full windscreen, rack, stripes, blockleys, plus all the other little bits n bob's. Mudgard etc.
Stage 2, been reading the pros n cons of G56 and for now I'll stick with AR.
Can anyone think of anything that they'd really wish they had added to their build ? (no sarcastic quality control comments, please).
Two extras I would not have are the side pockets (too small; too tight) and immobiliser (drains the battery).
MMC will fit Stage 2 components, but if you are looking to the full kit (throttle body/injectors, to add to high lift cams) a fair bit of tuning is required to get the fuel maps right, and the factory will not do that. Krazy Horse are the ones for dyno tuning, but as the factory will not supply your M3W with an unlocked (ie tuneable) ECU you might be better off specifying Stage 1 + cams and getting the Stage 2 ECU and throttle body etc fitted by KH. The AR exhausts are also on the noisy side. If you are thinking of racing you may find that they exceed db limits (as mine did at my last track day).
