My plan is to leave the OEM braces in place and add this carbon one:

I might do the carbon corner braces from turner you linked as well just for some added flare

I recently installed Ohlins R&T and it seems to have cured this problem, the violent rebound was something I would experience pretty much every serious country drive and could be truly scary at speed mid corner. As it was explained to me by a guy who tarmac rallies his M2C, stock rear has only 8-10mm of compression before the bumpstop comes into play, even hard cornering on a flat road will hit the bumpstop.

It's a large bumpstop and obviously designed to compress & absorb impact but I wonder how much testing they do on bad roads, doing laps of the Ring (provided you stay on the bitumen) or driving autobahns you'll never experience the bad rebound. Maybe the oem set-up is relying too much on the bumpstop and not the spring to slow compression as the limit approaches.

My Ohlins spring rates are 78Nm front & 160Nm rear, they are stiffer than the oem springs but the ride is a lot smoother, really noticeable over bad roads where now the car stays quite flat compared to before when it would be up/down and I'd be moving side to side in driver seat. Our Covid restrictions eased so I did a 400km country drive a few days ago, 1st with the Ohlins and I don't think I bottomed out in rear once, certainly didn't feel like I did which is a 1st for those roads in the M2.

BMW actually refer to it as a "Auxiliary damper w.protective tube" and it's common to the M2, M3 and M4. So probably quite a bit of testing. But it can be trimmed to give more free travel - particularly if the car has been lowered.

I can go back and check the Ohlins thread, but do you have any noise issues? There were quite a few people with complaints that seem to finally have been resolved. The thread made me a little hesitant to go with Ohlins R&T, honestly.

Mine also makes some noise, Ohlins + Vorshlag camber plates but it also made some noise with the Dinan HAS before.

It could depend of many things, springs moving while turning and hitting bumps wich is worse with certain camber plate designs.

It could also be play in the Ohlins shock when they used a different design bushing for some time.

It could be a bad install, top nut not tight enaugh, shock collar etc.

all this can be worse or less depending on tires you have, strut bracing, bushing wear and indexing. Noises could be fully normal too.

I think the most important thing when you get an aftermarket suspension if your not doing the work yourself (if you what your doing of course) is to find a good reputable installer that as a lot of experience with the brand suspension your looking at.

I spoke on the phone with 3dm Motorsports owner (Ohlins specialist and rebuilder) yesterday for 30min. It was by far the best thing I did to understand what was happening with my setup, 30min on the phone was worth 30 hours of forum browsing !

Is there an installer they recommend in Quebec or Ontario?

I have the dull knock only at very low speeds on uneven surfaces (eg paved), otherwise no issues. Ohlins Australia have confirmed with me the bushing issue and are replacing the bushings under warranty (my set were originally bought around July 2019, I'm 2nd owner).

I should think you'd be safe buying Ohlins now as the bushing issue is known and acknowledged (& no doubt fixed for future sales). I'm very happy with their performance otherwise plus it takes literally 4 minutes to adjust all 4 dampers for track or spirited drive.

Same experience here, the noise it's totally bearable to me but next off-season (winter) I'm sending my shocks to 3dm Motorsports to have them revalved for my lower spring rates and he will make sure I have the more silent bushing installed at the same time (if I have the noisy one of course).

I would ask Ohlins USA, I installed them myself.

Yes. I own two F87 M2s right now, 2018 LCI(N55) and 2020 Competition(S55).

M2 Competition definitely has a better suspension; which show much more stable movement in all conditions of roads and speed.

Not been in an M2C or driven one but after brace retrofit to my OG I felt the front suspension work and that feeling of course went into the chassis. Steering was a little better but I noticed the suspension/chassis response first.

It has been searched troughoutly that the only difference is the front brace and the weight of the heavier engine/brakes, that is the only difference suspension and chassis wise between the OG M2 and M2C.

Yes it's widely spreaded like that, but when you drive it you may feel the huge difference. I'm not sure what causes it, but M2C feels much more stable in the high speed andmore refined in all conditions of roads. And the idea about M2C and OG M2 uses same damper has not been proved clearly. Some says that BMW engineers has recalibrated the damper for the increased weight of M2C.
