Given that there aren't as many options out there anymore for springs, you can go with BavAuto, H&R, and Vogtland. You can run aftermarket springs with the HDs, but the Sports have a shorter shaft and are better suited for sport or race springs. And they cost the same. So, get the Sports if you're planning to lower your car. But if you're planning to do a whole suspension upgrade, the BavAuto Suspension kit is a pretty decent package: BavAuto springs and Bilstein Sports. I have this exact setup and love the stance of the car and the handling. __________________ moku 1996 318ti Cali Top w/ Downing/Atlanta Supercharger 2003 M3 w/ CSL trunk, splitters, & diffuser |
