So first off it is important to note I am dropped on RSR springs from a 2014-2015 Q50 AWD NOT from a 2016-2017 Q50 RedSport AWD. I mainly did this because the RedSport ones were out of stock and I got impatient. I knew they would fit because the suspension is exactly the same. The only difference I saw was the front drops a little more by 5-10MM and the front spring rate was 1K softer. I am extremely happy with the result. No issues whatsoever. Everything was direct fit with no modifications, squeaks, rattles or anything of that nature. The front is quite low but not unmanageable. Occasionally I will scape but its not actually on the bumper its on the lil plastic wind deflector thingies in front of the wheels and on the under tray but thats only on steep driveways. Will get an alignment in a few days and hope I can get toe into spec still since the front is a little lower than the RedSport springs. Wheels coming up next. Just gotta decide which ones I want!
