I just installed Öhlins coilovers and am really happy with them. For me this is a perfect street set-up with greatly increased performance and no sacrifice in ride quality. I also plan to upgrade to M3 suspension parts, Megan Toe Arms, and Rick's differential lockdown kit in April. The Öhlins give you lots of adjustment range and let you maintain stock ride height if you want. They also force you to learn the umlaut option on your keyboard Click here to enlarge.
