I had these exact same coils on my car.. I think your definition of "slammed" and zilvia's definition are different. I had like a half inch of preload, one collar removed from each coil in the front, and my rears drooped like an inch and a half to get the ride height where I wanted it. Also the right rear blew at my first track day. And the coil's OD is so large that they rubbed my tires. Now I have PBM and none of the issues mentioned before..
