My 2012 Cayenne seems much too bouncy. Even speed bumps send the car bouncing down the road. So I believe it’s time for new shocks. But when perusing the Tire Rack site, I see a set of springs that are “10% stiffer” and lower the car by ~1.5”. I don’t go off road, so was thinking about installing the Sach’s shocks and H&R springs. Pretty good reviews, tho none on a Cayenne. Anyone have experience?
