Yeah. I currently have Vogtland Springs in my M3 for about 15-20k miles I would say they are pretty close to stock as far as ride quality at first but my ride quality has gotten worse over time. I just ordered some KW v2 coilovers should be coming in either friday or Saturday. I know they are pricey but it really is worth it in the end.
