The first thread is from someone that bought a used set with no idea how they were treated, and the second set is from 2016? Find me multiple threads where people who have street-driven their MPS and had leak issues or don't bother really. |

The fact that the MPS is made by KW to BMW's specs is common knowledge, and the MPS has few issues that I can find. If you can find more, and a common theme that they are bad for street use, please do so. IME most guys running KWV3 instead of the MPS are doing so to either track the car, or to lower it much lower than the MPS will go, both of which can shorten the life of the suspension if not dialed correctly for those situations. I'm happy to change my mind about it though. I consider OG Shark to be a guru in this area, so maybe he can chime in. |

I just have been browsing FS threads for a while, just for the sake of it - And I see ‘a lot*’ of rebuilds for KW. I just saw one that was noted to have 10k on it (F30) these are old threads here and there, so who knows what was done and how they were driven. It’s just something to be aware of. Ex https://f30.bimmerpost.com/forums/sh...W#post20247061 *this does not factor in how many people can afford these mid range suspensions and then go on to sell or give a review. It’s not an exhaustive scientific measurement, just observation. Maybe the V3 sells more so it appears more vs other models.

I think the main thing with the rebuilds is what you hit on earlier when you said most guys with the MPS & KW don't use them that "hard". That will for sure extend the rebuild/replacement interval. Most MPS kits are not driven hard (and I'm not saying that like it is a bad thing) so you do not see this come up very often. One thing to keep in mind here too is when not driven hard the slow depreciation in performance can be almost imperceptible. I would bet there are quite a few MPS users out there that do not realize they could benefit from a refresher. Breakages are also going to be less with easier usage. With the KW alternative you start to see more users that are interested in either lowering more like you mentioned or a bit of track work. The lowering can absolutely be harsh on suspension components and axles. This can be corrected but more often then not is accepted as a part of what happens when you play the game. I do think with the KW you have more cases of harder usage which will bump the service interval up over the MPS. Not that there is much difference between the two but more usage driven in this case. I'm still not a fan of the MPS approach - the front rates are still relatively soft and too reliant on the dampers to help control the body - but I haven't seen much of a quality issue or anything like that with them. One thing that does irk me with the MPS is that if BMW thinks it is a better overall solution why did they give us the stock crap in the first place!! |

It was all about the price-point, and not creating better performance than the F80/F82, which they were dangerously close to already. |

OG Shark Whats the lowering range on the Nitrons? Does it have to be slammed or can i keep it relatively close to stock height?
I do want a little bit lower but not by much at all. Thanks!

Plenty of height adjustment - definitely not forced into slamming it. I prefer to keep my street cars around oem or maybe a hair lower as well. Can actually go a bit higher than oem all the way down to full slammed and anywhere in between.

FYI I have confirmed in the past that KW will NOT rebuild the MPS, since they view it as a BMW product, even though they built it! From other stories on this forum, when people have issues out of warranty, they either have to pay for a whole new strut, or just sell it and get another brand. I couldnt find anyone else besides KW that rebuilds KW suspensions, but maybe someone else knows something.
"Good afternoon, Thank you for reaching out to KW automotive with your questions regarding our shock service. If these are M performance coilovers those will be a private label that is exclusive to BMW motorsports and you would have to contact them for service."

Is the Ohlin R&T knocking issue overplayed like the crankhub issue?
I'm in the market for coilovers that can withstand occasional track days and have heard the Ohlin R&T to be superior to the KW v3. But there are also threads of several members having issues with it.... |

fwiw; i went with bilsteins, eibachs springs and gc camber plates(thanks DrKevM5)..About to be installed. Bilsteins have a hell of a reputation. Mine is a daily that might see 3-4 track days and fast backroad stints..IF i become a track rat, then I’ll drop the $5k on coilovers and another $5k on brakes…

I'm looking for linear spring as I'm a beginner track driver and don't want the variability. Which of the above would have that? Or do you think I shouldn't pick coilovers based on spring type since I can replace it with a linear one? |

KW uses 61mm ID springs; therefore, spring swaps aren't as straightforward. Fitting 60 mm springs requires machine work on spring seats. Feel free to shoot us a PM for quotes for coiners bundled with camber plates and perhaps a thrust arm bushing upgrade or track brake pads. |

Well I finally made a decision, today I ordered the Nitron R1 kit from OG Shark. Quite a few things factored into this decision, in no particular order:
-Ability to be rebuilt. I do plan to keep this car for a long time and it's valuable to me to have a system that can be easily rebuilt by the manufacturer when the time comes. -Buy once cry once/FOMO. I want the absolute best for the car i love to drive so much. I didnt want to save $1500 just to wonder for the rest of my life if I should have bought something different. With the Nitrons I can rest easy knowing that I pretty much got the best thing possible, short of the R3's or comparable $7k+ CS/racing setup that is beyond anything I'll ever need. -Full kit. The Nitrons come with everything including camber plates which I would have needed to buy separately if i went with Ohlins or MPerf. Not a big deal but its nice to know that the kit im getting is going to work straight out of the box with no hassle. The parts are all the same color too which is a nice classy touch. I'll probably create another thread specifically for the install/review of these once they come in, for now I cant wait, im so excited! Thanks for everyone who gave their input all the help and suggestions I got in this thread.

Build quality of the Nitrons is like nothing I’ve ever seen. Congrats. They make me smile every time I leave the driveway.
Best of all, they turn the car into a F’n scalpel. You’re going to be blown away on that first drive and every drive after. |
