Its m3 evo 5 door, wen its under hard throttle it drives brill no problems, but wen the camber changes of the road or goes a little bumpy, it feels like the rear end is trying to steer! only at 90mph plus. It Only does this if say u go over a bit on a hill, mainly wen the road changes from being flat. Very hard to explain!!!

Our theory maybe that its somethin to do woth the diff witch is lsd, and i think its a plated one! Thinking that maybe wen the weight moves off one side of the car, its sendin more power to one wheel.

Its actuallly dangerous, u be driving hard to 100 go over a little hill or somthing and it will force to one side. Hope someone can help, The diif its noisy at all, and its fully 4 wheel alighined! camber and tracking all spot on. It gets very twitchy on uneven sufaces.

Thanks Matt.
