Yup KW will only deal direct with bona fide warranty claims of their products.

I know of a couple of folk who've had their kit refreshed/rebuilt by Cornering Force in Harrogate, they're a certified KW rebuilder ✅

Query:

On a 2020 M2C with the following combination:

- MP coilovers, set to BMW's "Street" recommendations (~20mm drop, I think?)
- Stock 788 wheels (Front: 19x9 ET+29, Rear: 19x10 ET+40)
- Michelin Pilot Sport 4S tires Front: 255/35/19, Rear: 275/35/19 (+1 from stock)

What size of spacers (front/rear) would work to allow for NO rubbing and NO poke out beyond the fender walls?

TIA.

R.

Want to share my experience with the MSS adjustable spring kit.

Have done 300 miles on them already. Still not properly aligned in the rear, fronts should still have OEM alignment but the drop might have changed things...

1. Running 0.25" drop all around, based on the separation of the adjustable plates being 0.75" apart. Rears definitely dropped more than the fronts, gonna have to adjust for that. But from eye balling looks like rears went down 0.5" and fronts 0.25".

2. For sure more comfort. The bumps on the road are much smoother and the comfort in longer distance drives is improved a lot.

3. More compliant. When punching through entrance/exits on highway the bumps are less bouncy in the rear. Soaks it in much better.

Notes: no issues with sqeaking, only happened in the very beginning but that's gone. No complaints at all really. Only thing weird is the rear springs are kinda slanted but KW HAS and MSS pics show this is normal so oh well, functions fine.

Score 9/10
Bang for buck if you purchased at a discount like I did. Full value 900$ I'd lower the rating a bit but still this is the route to go if you want cosmetic enhancement, some comfort, and cost efficiency.

Good news. Thanks. Enjoy!

Yes. It would be even better if he posted it on an MSS Springs thread. This one for example:

https://f87.bimmerpost.com/forums/sh...&highlight=mss

Or - for maximum impact - start a new one devoted to how wonderful the customer service of his supplier is.

I then ordered Ohlins

What was your impression of comparing the three different suspensions? You did't mention how the Ohlins compared.

Do you know what the Spring Rates for these springs are?

If I were to do it again I'd contact a BMW dealership that has much experience installing the MPS and literally buy the exact tools they use. The rest of the job is cake, it's just the strut tops that are the issue.

The pass-through sockets worked fine on the end-links, zero issue there.

Is that a 10mm socket that snapped in the Pass Through Wrench? Did it snap coming off or putting on? How much Torque is required to get this Top Nut tight? I am about to put on Camber Plates and Vorshlage says just Impact it down with short bursts of Impact Wrench.

I'm swapping for softer springs this winter because our roads are so bad around here, on track the Ohlins is a gem, full send on rumble strips no problem and they seem to be some of the most durable from my research.

It was the torx bit. I thought that it might have been a bad one, so I bought a new one, and almost snapped it as well. And I was following the specs exactly.

i track a crap load.... i have the BMW M2 Comp... and on our australian roads the OEM suspension is jittery as hell and just way to stiff for day to day driving.... i also took my stock BMW M2C ... down to my race track and posted a lap time.... (im use to the track and i drive it alot) got a reference lap... put the MPC on... and a set of Semi Slicks and knocked off 4 seconds a lap off my stock time i posted in the car stock... set up correctly the MPC are a great coil over.. that has the benefit of being covered under BMW warranty. only worry is that they are KW rebrands.. and i know the KW are susceptible to shock leaks....

I just want to ad that if you were looking to get MPC I would not hesitate, I think the BMW M Perf suspension is much better adapted to the M2 chassis than the Ohlins. The Ohlins R/T has some advantages like dfv tech and durability and easier rebuild/revalving but you want a good turn key solution MPC is unbeatable. Yes some get leaks but it's a very small % of all the ones on the road.

If I would do it again I would probably go this way. I will have my suspension out for the 4th time this winter and I really hope this time it's going to meet my expectations cause I'm starting to have some taughts about parting-out and going to a more track ready platform..

Having the same query…
Would like someone running the setup to confirm this.
Thanks in advance!

In the front no spacers will fit, as this wheel setup already touches the inner housing at cornering. Same topic as with the winter tire setup (like PA4 in 245/35 19)..

Confused.

I thought the 255/35/19 on stock wheels was "safe"?

Or is it the MP suspension that makes this difficult and causes rubbing?

If so, what's the solution?

I can tell you the 10 works for prefect fitment in the back and a 12 would also work and be bordering on poke/flush

I have 12 up front and it is not a perfect/flush fit and it does in fact rub on 3/4 lock with mp4s in stock sizes

It's more of a fender liner brushing sound than a rub. I'm sure a 10mm up front would be brush free

It's kind of unfortunate in my opinion if I want the perfect fitment with stock wheels (15 up front) I'll have to modify the fender liner.

Hope that helps.

[chief1richard]

Am about to switch over my Stock Suspension to M Performance with Vorshlag Camber Plates. When ordering the Vorshlag Plates you need to know the diameter of the Damper, which its says is either 12 or 14 MM, for the M Performance Dampers. Cannot find this info anywhere. Does anyone know what they are? I would measure them but do not have them yet.

It really depends on the tire in use.
255/35R19 Conti Winter TS830P for example are rubbing.
245/35R19 Michelin Winter PA4 are also rubbing (yes, even as 245! They are extremely wide).
245/35R19 Michelin Summer PSS are of course not rubbing (stock size).

Above results always based on stock offset and rim sizes. It does not really depend on the coilovers..

[kart driver]

I have constant noise with my M Perfomance coilovers when going over bumps. The front and the rear axle creak all the time when I go over speed bumps or potholes regardless of their size.
It is a bit annoying to hear this sound all the time. The noise is not very load but it is distinct.

Have anyone experienced same issue?

Just wanted to point out that I rub the fender liner with 10mm spacer up front so may still be problematic.

The larger one (as the smaller shaft diameter is for the dampers on a conventional 2 series).

[chief1richard]

After reading this thread I am having second thoughts of ordering MP Coilovers. Am I correct that after installing them with the recommended 15mm drop, that my Stock Wheels with +1 sizing (255/35/19, 275/35/19, will rub? If so I may have to go with just Camber Plates.
