Best current adjustible shocks?

Hello all,


I'm looking to replace the original shocks on my M5 (anthracite), if I'm going through the trouble I want to get something adjustable, mostly just because. The stock suspension is really nice, but I am considering also squaring up the stance so some adjust-ability would be nice for dialing in the balance. I'm open to coil overs but don't need them- again the stock springs are pretty good, and I'm not interested in significantly lowering the car at all, the stock stance looks great. I'm not a fan of progressive springs at all.



I'm leaning towards the Koni yellow's (not Dinan, as I wouldn't want to run their springs). Bilstein is out due to not being adjustable. I've seen a lot of other brands out there but aren't familiar with any of them in particular, which is why I was leaning towards Koni but also why I am posing the question here.


Thanks in advance!

for what you want, none. koni you have to take apart to adjust the rear which is pointless. for a square setup without huge spacer iirc you have 3 options oe, bc coilover and gc coilovers. its nice both coilover option come complete with camber plates also. i have the bc and dd them and they are great for the price, not bad riding at all and i basically have it at stock ride height.

Thanks for the feedback. I'll probably go with the BC. I know Ground Control makes good stuff, but they're just using the Koni shocks.

How's the adjustment on the BC setup? I probably won't adjust often, but it's nice to be able to do

You can get extenders for the rears with BC's so you can adjust w/o having to remove the rear deck, not sure if anyone else has that option... although I'm sure it wouldn't be hard to fab something up.

I have BC's on one of my M5's and PSS9s on the other. If you aren't tracking / hitting the back roads around here, it's hard to go wrong with BC. YMMV and all that.

GC doesn't just use Koni shocks. The front shock has a special body shape negating the need for a spacer on the E39 and unlike what's stated above, the rear shocks are adjustable from the top as the fronts are and do not require removal from the vehicle.

Depends on what you want to spend. MCS 2-Way or 3-way are the best one can buy for the E39 M5, but in the $6-7k range.

^Yup to MCS. I just ordered their 2WNR for my e60 below:

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:

https://www.m5board.com/vbulletin/e6...cks-coils.html

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.

Thanks for clarifying. Do you know if they have the capacity to easily have a remote adjuster? Or is access fairly easy when installed?


It looks like it would be still between BC and GC. Either one should be an improvement over stock, which is already pretty damn good in my book (my suspension is just starting to get a little tired, and at the cost might as well upgrade).


MCS is just too far out of price range compared to what else I could do with the money (euro floating rotors, etc.), vs. my concern with BC is actually how cheap the system is- I'd feel more comfortable spending $2k on a set of coilovers than $1k, because I would be questioning what compromises were made in order to be able to manufacture and produce a set at a profit at the $1k mark.

The rear are top adjustable like the front are. Access is under the rear deck. The mounting nuts are accessible so I'd guess the adjusters are also. I don't know how remote adjusters are typically fitted. The GC kit also includes adjustable camber plates.

I have a much older GC kit so all of my information is from their website and talking to them. It'd be worth giving them a call and discussing your concerns, wants and desires. They seem very helpful and willing to discuss suspension.
