I have the Eibach Pro-Kit springs installed with Bilstein shocks, and YES they do fit...but the ride seems a little too ruff for Pro-Kit and regular HD bilstein shocks. This might be because my mechanic installed the rears upside down or didn't cut the bumpstops in half (or, as C25A1guy said, they're not meant to carry the weight of my
[email protected] sedan)...I've yet to investigate.
FYI, the improvement in handling cannot even be compared to my old stockies. Also, if you don't rotate your tires every 3k, you'll go through your front tires pretty quikly.
