The M5 and M6 both suffer from too much frontal weight, their weight balance is 55/45% I believe which doesn't help matters when their is over 500hp going to the rear. The best M car ever was the E30 M3 and it's weight balance when more to the rear where the driven wheels where (a better designed chassis).
Enjoy the pink skies in your world mate. Because what you are saying is just plain wrong.
Tires are one of the key determinants of a car's performance, suspensions allow the tires to work better. Changing suspension without better tires is a waste. Tires alone are good for 4-5 seconds in a sub 2 minute roadcourse.....no other mod will give you this.
If I were out for track performance, the single biggest improvement to the car will be tires.
