have to say - i tend to be a tuning expert (not as good as some though) and i might be abl to help a bit but i struggle to pull it out of a nice 90 degree tailslide. Try making the dampers 10 each way, reduce the rear d/f (this helps get the tail out) and stick SS tyres on it. The brakes are actually quite good for a road car, but they do have to stop from 350kph. No brakes are that astounding. I am after some really good settings too but these might help.
