Had stage 3 suspension put on 2 weeks ago and what a difference. Very neutral, understeer almost gone, will have rear stiffened at 1,000 mile check-up. Anyone who feels like I do with respect to the stock M5 handleing needs this installed. I also got a short tour to look at on going developments and there where proto's of the cold air intake (in carbon fibre)with custom throttle bodies and aluminum mufflers. They where also working on custom headers, intake plenum mods and a light weight cluch system all of which appeared to be less developed.
