Yeah its not a very low lowering spring, but of course I also had all new isos in place. Im not sure if I can blame the rough ride on the MM springs or the combo of springs/Bilstein hd shocks n struts, however it did ride VERY rough, but it didn't really bother me, I'm young and don't mind a rough ride, but even my mechanic who installed them commented how very rough it rode. I also got lots of complaints from my passengers though on the MM springs. My steeda progressive rate springs ride way softer, but of course don't handle as well as the MM springs.
