He's got M6 Reps on there.
Im sittin on Bilstein Sport Shocks with H&R Sport springs, the drop was around 2". That left a 2 finger gap front and rear with 18in rims on.
If you still want a comfy ride, go with koni yellow w/ Eibach or the dinan stage 1. The drop will not be as much as what i got but it wont be as harsh. I personally dont think the ride is harsh, but others on here want their cars to drive like Cadillacs.
