recent feedback from one of our customers, CKS with Swift springs E60 M5 application:
"The CKS coilovers and SWIFT springs were everything you promised. The car now feels very nimble. I was really complaining a LOT when I first picked it up as it felt it was very "heavy" in the front with the stock suspension, even in "sport" mode. I have a 2008 Dinan 550i that I feel very comfortable throwing into corners but with the M5, well until now, not so much. However, now I am slinging this bad boy into tight turns and flying around curves. COMPLETELY different feel to the car. And as I said, it is a "sporty" NOT "bumpy" ride with the SWIFT springs-exactly as you described. Uh, and value....price for these things ROCKS. Can't imagine why I would spend more for the others we were talking about at first. (could be first time EVER that I saved cash on a mod and was thrilled with the end result).
A BIG part of the transformation of the beast! "
