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

When you rebuild a damper, a professional will take into account your current vehicle weight, weight distribution, and purpose to define the proper damping curve. So you can get your R&T rebuilt according to your cars spec and it will outperform any out of the box suspension

No. But that would be a "revalve" not a rebuild anyway. A rebuild just gets you back to like new condition.

I wouldn't bother rebuilding them if they are working fine and not leaking.

Sounds like he wants a revalve, which would include a rebuild.

One benefit of the MCS dampers is you can upgrade to a higher level of adjustability whenever you send them off to get rebuilt. So you can turn your 1way non-remotes into 3way remote reservoir, etc. It's a nice way to work your way up to more complicated suspension set ups as you get comfortable with using a high-quality damper. Not sure if that's an option with other dampers.

I’m the ‘mechanic’ for the car I share with my 21 yo son.

If track performance matters…

He likes broken-in, 2 year/30+ hours track time Ohlins R&T with 400-700 springs. He also likes brand new MCS 1WNR with 650/750 after adjusting the front bar to a softer setting. We just did this.

He runs low 2:09’s at VIR with either one. The new MCS dampers aren’t faster, but I think they improve brake pad and tire longevity. Don’t ask me why…I won’t be able to explain it.

The guy that did my suspension has revalve included in his rebuild service (if it's wanted), in essence it's only changing the shim stacks so it's nothing fancy...

Bumping this back up.

I have Ohlins R&T installed now from the PO. I believe they're well past Ohlins' recommended rebuild frequency (track hours; I just put on 4 in the last weekend, my first time out with it). This is a dedicated track car that will occasionally drive on the street. Considering reaching out to 3DM and working with them to rebuild and get them more purpose built, but also considering just jumping to MCS or JRZ (being local to Chicago with Olsen Motorsports nearby would probably be very helpful if I went the JRZ route). Obviously sticking with the Ohlins would be more economical, but I don't like the tire/wheel/spacer compromises I'm having to make, and I feel I'd move away from the eventually anyway. Any thoughts are appreciated!

How are you needing a spacer for your setup, I'm curious? That's usually a rim offset/ tire width issue unless I'm missing something.

I agree. I'm running 18x9.5 Apex ARC-8 +35 square with Conti ECF 275-35. Apex notes that coilovers with "less clearance" (Ohlins being one of them; MCS and JRZ are not) may require a 5mm spacer up front to clear. I have that, but I was hearing rubbing on some corners after a recent track weekend. When I removed my track wheels afterwards, I noticed obvious wear on the FL inside and rubber on the spring, so I was clearly getting some rubbing there. I've read the ECFs run a bit wider than most and I was also underinflated for a bit, so neither of those helped I'm sure. I have a 12 mm spacer available and enough camber where I should be fine, but I also ordered the 3DM "spacer" setup that raises the whole thing and should eliminate the need for a spacer at all.

yep, most places do.

No, they're seperate, with the re-valve being cheaper.

Of course, you can have a tech do both at the same time, but you'd have to spec that.

Sure, but who is only revalving a set of shocks that needs a rebuild, like this guy? 3DM service rates are a bargain IMO for Ohlins, just over $600 to rebuild/revalve

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.

Does 3DM do anything additional to the Ohlins from Factory?


I got my Ohlins Dedicated Track from Tirerack. I love them. But you are on point, jarring on the street but at Sebring with the bumps it SOAKS it all up well. I have it set a few clicks below middle

I probably will be lol. Went up to 450lb/784lb from 343/685 and it's a little bouncy. And because the rebound is tied to compression, you can't slow rebound down enough (as it will just invoke more compression). So since I only have 1k miles on them, I'd send them to Barry to just re-valve for 2kg heavier springs.

You mean the advanced track day kit from Öhlins? On those TTX shocks you can upgrade from 2-way to 4-way.

Agreed, in that scenario, a revalve makes sense. You're still well within test & tune territory IMO. What setup are you running?
