Thanks for the input!
You know it so depends on the spring rates you chose for your kit. If you are using OEM dampers and you go with one of the softer rear springs I think you would be hard pressed to feel a stiffer ride. Most people don't realize this but your ride is usually dictated by the rear springs not the front. I would choose a GC sleeve kit over a H&R springs only any day of the week.
