i dont personly have them but i know two cars that do, one car has the complete edelbrock suspension package on it and its nuts, you can take a turn like nothin and still rides real smooth and the other car has eibach sportline springs with edelbrock strut and shocks and works great but has a rougher ride, i have steeda's drag springs and thats a rough ride, makes a car with eibach springs feel like a luxary car smooth ride
