I've got RS-R spring on mine. Had them with both the standards dampers, and then my current gearclimb, potenza mixture. These were supposedly 40mm drop, and in my picture ( <--Member pic on left ) the car sits really nice on 14's with 185/55 tires. The ride is nice and firm, pretty solid springs but you won't bite your tongue off. They were softer with standard dampers, as with my current set up running 15's now ( 50 profile ) it can be a bit bumpy on our sh*tty surfaced roads. All in all though, very nice springs for the normal commuter who goes nuts now and then.
