Sorry for late response I came down with the stomach flu on Thursday morning. Just recovered! To answer your question on ride quality compared to Raceland we have very happy customers. The Raceland spring is much stiffer than ours. Hence why their coilovers ride bouncy. I believe Street Edge coilovers are great for a driver looking to get a little drop and freshen up their suspension. Unfortunately some of the noise complaints where installation related. There is a factory washer that installs near the top hat that you must reuse. Some were tossing this washer aside. Also you must open the hub wide enough to properly seat the housing. We also took steps by using a Loctite during assembly to help prevent any noises. Hope this helps.
