MCS 1WNR or 3DM Ohlins "Trackday" or JRZ RS ONE

[lvm3sm46]

I keep going back and forth between these two. I haven't found any reviews on either of these "kits" for our platform. I had intentions of just doing a basic lowering spring & shock replacement but knowing how I am that won't last long.

A lesson I learned with my last car, I just kept upgrading to better and better and wasted a lot of money in doing so.

Edit: also now considering the MCS 1WNR as they are based in the states and seem to have great customer service.

Intentions for use: weekend fun whether thats twisties with the boys or a track day. No daily driving, no grocery getting.

All opinions welcome

Can't give you any feedback between these two but wanted to point out that there's a really nice basically new set of MCS non-remotes in the FS forum for around this price. Curious to hear the opinions here though. I have the R&T and might as well have gone with one of the more track oriented options since I barely drive the car on the street.

Worth noting those MCS 2WNR dampers are just dampers -- no springs, mounts, camber plates, etc. You would probably be looking at another grand to get those on a car.

That ad isn't clear, are all four shocks rebuilt or just the fronts?

3300 seems like a lot of dough for used non-remotes

I can chime in about JRZ RS Ones since I have them. However, I daily drive with them so my usage isn't the same way you intend to use yours. I've got one track day, a few mountain runs, and lots of long distance miles on them.

But I've been really happy with them so far. I came from ASTs and found the JRZs to be more comfortable on the same spring rates (450/550).

I've yet to really test how well they handle kerbs but they soaked up the ones at Roval at Auto Club Speedway very well. Never did it feel like the car was upset when I ran them over. I may have to "stiffen" them up more to really see how it handles the kerbs there.

Durability - I am overdue for a rebuild (60k+ miles on them) but they still feel like they did when I first installed them back in September 2019. No signs of weepage but I am using dust boots over the springs so that might be extending their lives.

Feel free to ask if you have any questions about them. Hopefully I can answer them.

zzyzx85 Thats actually an impressive review. 60K miles on them, daily driven and still comfortable. If you were not daily driving them would you increase the spring rates?

Also can you share the details on how you had them built out? Street or race plates? Rear mounts etc.

Where did you purchase from?

[zzyzx85]

maybe 550/650 or 650/750 to control the weight transfer a bit more. I'm on 255/40-18 tires so I've got some sidewall to eat up some of the harshness of the roads around here.

I didn't buy them from Apex but sort of pieced them together from what I had. I'm currently on Ground Control Race camber plates up front and GC Street RSMs in the rear. I'll be swapping the Race out for Street plates, which I also had laying around lol. With daily driving and the crappy roads in SoCal, the spherical bearing on the Race plates developed a pretty noticeable knock. Rear springs are sitting on GC weight jacks. I believe I have helper springs only on the front.

I purchased the JRZs through Inertia Laboratory in TX. Mostly worked with them through email and phone. Excellent group of guys to work with. They helped me with getting the ASTs working before I ditched those for the RS Ones.

zzyzx85 thank you

I’ll chime in here since I am on JRZ RS2 non-remotes (650/750 spring rates) and I was also cross-shopping btwn these and Ohlins. I mainly use my car for track days and weekend “back-road” driving. They’re fairly comfortable on the street when you turn comp/ rebound down, but I wouldn’t want to daily drive on these. On track they’re awesome, soak up kerbs, bumps, imperfections extremely well and keeping the car balanced.
IMO The JRZ is a more track-oriented setup that can handle street driving very well, whereas the Ohlins are more street-oriented and you can turn them to a more track-focused setup with more aggressive springs, camber plates etc.
Based on my car use the JRZs turned out to be the best option as expected (and more). However if I were to stop tracking the car I would see no use to having them on and probably the standard Ohlins R&T would make more sense.

I would avoid the Ohlins, heard questionable things about them.

I had 3DM Ohlins Dedicated Tracks on my E46 M3. They were incredibly stiff. Pretty jarring on the street.

For context, my JRZ RS Pros & MCS 1WNRs had the same if not stiffer spring rates and rode considerably better on the street, and track. I would highly recommend the MCS 1-ways over the Ohlins; worth the extra money.

700/900 would be rough if it’s not damped well. How did the JRZ and MCS compare with each other?

JRZ RS Pros I was running 600/900, ride quality was better than stock. Loved the dampers themselves. External reservoirs, easy to adjust, extremely well dampened.

MCS 1WNRs I'm running roughly 700/800 (true rear, so hard to say exactly) and ride quality is also amazing. I like the fact that they are one-ways, for now, ease of adjustment, less to think about ... plus, when I'm ready, I can easily upgrade my existing dampers to 3 way remotes; the fact that the dampers are modular/upgradeable is a huge bonus.

JRZ RS Pro vs. MCS 1WNR, I would pick the JRZs. Two way, external reservoir...hard to beat. MCS 2WRRs are more comparable to the RS Pros, if I had to choose between those, I might go with the MCS. Because they're headquartered in the US, customer service and servicing is a piece of cake.
