Time to upgrade my current coilovers with a full motorsport/competition MCS 2 way system.
At about 75,xxx miles I installed CKS Coilovers w/swift springs. A bunch of us gave these a try back in 2012/2013. I don’t know how many are still on them today.
My original thread can be found here:
For a relatively “unknown” brand, they held up pretty well. Now, six years and 87,000 miles later, it’s time to replace them. 87,000 miles is good run for a “performance” upgrade. Time to upgrade again! My choices:
1. KW v3. Off-the-shelf solution. Rebuildable. No surprises. Very good street solution.
2. Ground Control. Rebuildable. I have a custom GC setup on my e28 m5 that is a scalpel on the track, but can knock your teeth out on the street. GC now makes an e60 solution, so I was leaning towards GC to build a more street/track solution for me.
3. Bilstein. I had a PSS9 system on my e39 m5. They now make a system for the e60 m5, so that was tempting as well.
4. CKS. 87,000 miles is a good run! When I installed the CKS, I wanted to try something different — and for nearly half the price of the KWs...why not give them a try and drive them into the ground?
5. MCS (Motion Control Suspension). The over the top, rebuildable, motorsport solution that can be dialed back for the street. One of the MCS owners also founded JRZ Suspension Engineering and Moton Suspension Technology. My shop, OMS, installs them on many of their racecars and their client’s racecars. And, Imma sucker, because racecar!!
MCS machines and assembles their components in Alpharetta, Georgia. With the holiday, it will take a couple weeks for them to build my system. From what I understand, I will be the first e60 m5 running their suspension.
I’m looking forward to making a big jump in my suspension game with my e60. Will update this thread once I get them sorted.
