I am using OEM non-sports springs (base model 335d). You are correct. I just looked it up on the Bilstein site. Too many things to remember. When you referred to "sports springs", are you saying that I can get some BMW sports springs that will not lower the car?
Mods-Etc: Quaife LSD w/VAC finned diff cover, M3 Rear SF Bushings, M3 sways & OEM Susp Front/Rear Cmpnt Kits ('cept strut brace), GC Caster/Camber Plates, AC Schnitzer M3 Sport Springs, JRZ RS1 dampers, JBD 100%, Goodrich SS brake lines, non-stggrd APEX ARC-8 18" wheels with Michelin PSS tires (winter OEM 17" wheels and Blizzak LM-25).
