Default Looking for feedback on MCS suspension

I spent 45 minutes talking about aftermarket suspension options with James Clay a few Fridays ago as I was considering an upgrade. However now there's a need to do something as my left front strut is leaking, so it's decision time: stick with OEM or go all in with an MCS 2-way non-remote setup.

We talked about TCK, JRZ, and MCS, and based on the car's usage he suggested MCS if price wasn't an issue, with 750/850 springs. The car is a DD and sees 8-12 track days a year with a lot of them at Road America. My concern has to do with how the car will ride on the street as I don't want to have it be uncomfortable, which I realize is a completely subjective thing. James said that it will be just fine, and while I have no reason to doubt him, I'd like owners to offer up some feedback. In searching here and other forums I haven't found a lot to help my decision. I thought about posting in the E46 M3 forum but figured I'd start here since it's more likely the track crowd is crazy enough to spend this kind of money on a suspension setup.

So please let me know your thoughts - - thanks!

Have the two way reservoir set up which I think you know? Even though I do not DD my car I would have no problem doing so. I used to DD it when I had the Motons and loved the set up. Was similar to the MCS I have now but actually felt the MCS with the higher spring rates I'm running now, compared to what I had while running Motons is more compliment on the street.

My spring rates are almost identical to what James recommend. My car also has solid bushings, upgraded sways, and less comfy seats (recaro profi xl) compared to your csl. Some local guys have had the chance to ride in my car maybe they can chime in or you can PM them. Most recently 405 got to drive my car for a bit and also CM-2 has been passenger a few times.

Ive got nothing to add here except for some MCS pron...

Maybe spend a tad more on external res so you can mess around with canister pressure for street vs. track?

Do it!! I would go with the 750/850's with confidence. If it's too stiff you can easily lighten it up some. The improvement in handling will be worth it compared to how it will ride on the street.

Default Re: Looking for feedback on MCS suspension

Logically I would say try to understand where James is coming from. He has relationships with MCS and therefore it would make sense he leans toward these products. This has nothing to do with him or the products. While I cannot offer any specific advice on the exact system you are questioning, I think its important to know what you're trying to achieve. You mentioned 8-12 track days. Based on this are you counting a track weekend (multiple day event) as one day? If this is the case it sounds like the car is getting worked very hard and street driving may not be the priority.

Any high priced coilover will achieve what you are looking to do. But if you're heart is set on this brand I would suggest looking into the external reservoir version especially based on your usage. Considering the total price to complete the kit it would make sense to go for the high end version. Why? Because the 2-way external can simply handle the workrate better than a system sharing the functionality in the same tube. The downside to this system are mounting locations around the engine and heat exposure. The biggest factor against this setup is heat from the engine. The other important question I ask is are you adjusting your suspension based on the areo setup for different tracks? If not then maybe the external version might be overkill.

Now if you're not set on this brand I think you can also try a high quality single adjustable coilover and achieve similar results. I know several guys who run singles without an issue. I have found guys with dedicated track cars running singles. At your next track event have a look at what others are running and ask around. Its a great way to gather intelligence on setups and kits.

Needless to say let us know what kit you decide to go with. I'm sure others are in the same boat with questions and concerns. One thing I do like about MCS is they are located here in the states and easy to get in touch with for questions.

MCS are the hot setup (HSU), and I trust James advice. However (comma) that's a lot of coin to put into something you're going to beat the shit out of on the street for the majority of the time. They'll work, no doubt about it, and you'll love the way the car handles the on-ramps, curves, etc., but dang...

If the spring rates are too harsh, you can soften the compression setting or go to softer springs. Takes a few minutes at the track to swap in new springs w/a good coil over system.

James can help with setup too, so that's a plus.

FWIW, racers swear by MCS stuff, even over Motons which were the previous HSU. Some of the fastest west coasters run MCS. After tires, shocks make one of the largest lap time differences and make the car so much easier to drive on bumpy tracks.

If you can swing it (and the rebuild costs -- not sure how frequently MCS stuff needs to be rebuilt), then get them. The remote canisters just add another layer of complexity and tooling to bring with you to the track (Nitrogen bottle, proper gauge, etc.).

If it were me and I was single with my current income, I'd snap buy them. Plus, you get a sexy BW t-shirt right now if you spend over $250, so chicks will dig you. What's not to like?

I have MCS singles w 600/700 springs, and street ride is much improved over previous GC & AST singles with softer springs. The dampers ability to soak up the initial compression (expansion joints, pot holes, etc. ) over my previous suspensions is night & day.
Can't speak for MCS 2 way but I'm sure they deliver

I'm not sure I'd want to bang up an expensive set of coilovers on the street. They will take a beating just driving up to Road America until they repave I43/57.

But...James Clay is probably one of the very few resources you have for comparison between the different setups. Very few of us have had different $3k+ suspensions on our car.

I've driven/installed a couple kits and they are some of the smoothest street driving kits out there. They ride noticeably better than Bilstein/KW/TCK/any Koni based kit despite much higher spring rates. The build construction is also excellent. Really top notch stuff.
