I have a Q4 that i´m driving in the Alfa Challenge series here in Sweden. I started with Koni dampers and Eibach springs but that is not for serious car driving. I know mounted the FKKÖNIG SPORT and tried it now for one race. What a difference. They relly work nice togheter with thicker antiroll bars. The quality seems to be very high and the price is really nice.

I also tried INTRAX on another car a couple of years ago and they also feelt like a "high quality product". Never tested them on track though.
Just a tip...
