"Great springs without sacrificing ride quality"

Review Body: Bought a car with H&K super sport springs on stock struts that was similar to the ride of a go-cart. These springs are the best of both worlds, it has great realistic clearance without sacrificing the ride quality and better than even the stock ride, in my opinion
