Help me finally choose my coilover setup

[9kracing]

Are we sure that Dinan ran RS2's and not RS Pro's?

Nope, and I can't find anything definitive. I thought they were RS2s but I could be wrong, God knows I have been before.

Whatever I end up with let's get em' on the shock dyno.

Definitely!

Well after all that, I ended up finding a deal on marketplace for some RT's. I'm even going to use my existing strut mounts at first before moving to plates. These also came with the 3dm spacer which is nice.

Will report my impressions.

You won't be disappointed. You can rest easy knowing you have one of the best setups. But, I'd still play with it. I'd get plates with 2.5" seats and move down to 325 (lb), 336 (6kg) or 343 (60n/mm) 7" tall (170-200mm). The 400lb front springs are a bit much imo.

Definitely a very good choice. Though I would not reuse the existing rubber mounts. These dampers will perform better with monoball strut mounts. Depending on how much lower you go, you may need plates to dial back camber into spec.

I'll give them a shot to feel them out, but will be changing them regardless as they are quite hefty.

Opportunity to save around 2lbs per side on the front:

That's the plan but I'll run the stock mounts first then will be able to compare the difference in feel switching to plates.

Thinking to just go with Ohlins plates from 3dm, they look exactly like Vorshlags but less $. and I'll actually have customer support as opposed to something from Turner.

Let me get this straight….You had a set of JRZ RS2 dampers and went to Ohlins R&T? Uhhh yeah that’s a downgrade.

All you needed to do was make sure those JRZs were good and purchase some “street” springs and camber plates. I’m not sure if many realize but a really high quality set dampers will ride like butter when setup correctly. It’s wild because they can ride like an aggressive caddy on the street and handle like a train on rails when dialed up.

JRZ RS2's are not high end, they are twin tubes like a Koni, just with adjusters. The Ohlins are monotubes, inverted in the front.

What’s your point? Because it’s a twin tube design means it’s not high end?? Not all twin tube designs are created equal. There is a huge difference between a Koni twin tube design and other high end offerings. The Ohlins TTX and Penske race shocks are both a twin tube design and are above and beyond the Ohlins R&T monotube design.

For context….I run currently run TTX Pro on my m4 GTS and JRZ Motorsport series 11 on the e46 m3. Ive tried A LOT of other suspension setups in the past ie Koni, KW Clubsport 3W, AST 5200, JRZ RS1 RS2 2WR, MCS 1WNR 2WNR 2WR, Moton 2WR (before those guys left and created MCS).

My point is the RS2 is not a high end shock by virtue of the design and performance capability, as well as my personal experience with them. As you know, there is a difference between these brands' consumer grade offerings and their motorsports offerings. The TTX and JRZ motorsports shocks are indeed very nice, and they also cost $8 to $9k. You cannot compare a TTX to a Koni/RS2/etc because they operate in completely different ways, even though yes, they both have two tubes.

Perhaps it is a downgrade! I have no risk in the Ohlins at the price I got. If I don't love them I'll be trying TCK or MCS 1 way.

From my understanding the JRZ were better suited for the track in our ( cobra ) testing. The other thing is the rebuild interval is very short. Dialing the kit in from scratch wasn't going to be as easy as you made it seem(or maybe I would've gotten lucky). Not a ton of data points to go off from others and all the little bits(rear adjusters, bump stops etc) add up in $$.

Ok, point noted. With that said, idk man….I ran RS2 on an e46 (12yrs ago) while having Ohlins R&T on my e92 m3. I drove them back to back and to me that extra bit of compression adjustability felt better. It was very apparent on city streets soaking up both small and large bumps in the road. I will say the default spring rates on R&T aren’t great. Swap them out for swift 60mm springs for a much better experience.

JRZ RS2's are not high end

Did you just compare a Koni to a JRZ?

I use them with Millway plates, 1:1 oem stack height and also what Ohlins themselves spec for their track offerings.

Yes, it is in the same category as a KW V2 and a Koni double adjustable.
