If you're DD'ing the car with little to no track use, go with the progressives.
Several customers have told us the ride quality is better than stock.We haven't experienced any bounciness whatsoever!
So aside from the improved stance and handling characteristics when you really push the car, you'll also receive a comfortable ride quality for daily driving.
