When you say "bumper" does it mean spring or shock? Anyway it cannot be normal that either brake after 5000km!!
I've had mine for 25000km without issues and I expect lot of km:s before change.

do the MP Coilovers need to be installed by the dealership for the warranty?

I mean the shock. I guess that they could live longer with smoother roads than in my country (Belgium). Still, they are designed for performance, not longevity, and are supposed to live much less than normal bumpers. If one breaks, you have to replace the pair (front or rear), which means a cost of 1kÄ + manpower. Still, I read that KW can refurbish them for ~100Ä per shock. I wonít do it, as my suspension is still under warranty.
Interestingly, the mechanics at my BMW garage told me that even the stock coilovers of the M4 GTS break easily...

In a weird weird way, I have an M2C and have to agree with this spot on...

On perfect, track like roads the car feels great... but if you are driving the car hard into turns, or up highway on ramps and there are any bumps or imperfections in the road, the car feels like it wants to fly away or takeoff and it has an odd amount of side to side sway. In many ways its un nerrving and kind of makes me lack confidence when driving hard... considering the Mpss to help fix this... shouldn't have to do this in a 60K + M Car.

Stupid rule but true. I had mine installed in a race shop so they could do ride height, rake and corner balance. When my right front shock blew out they said it’s not covered due to outside install. The install had nothing to do with failure but BMW goes the extra mile to not cover. By, the way, they wanted $1,100 for one new unit ( part only)...I discovered KW will rebuild both fronts for $300.
After all of this, I put on MCS 2NR and they are a big improvement over the MP.

This is exactly what I felt with the stock suspension. As posted above, the stock suspension is not only a joke, its an imposition and a shame!

Do the MPS, you'll love it! It's more complaint on normal roads and you can properly corner the car with lots of confidence and precision as it should be from the get go. The rear is now planted perfectly well, no bouncing anymore. The MPS transforms the entire car, into a much better car.

By far the best and most important mod to this car, and at least for me, it's night and day!

Before buying my 2018 M2, I test drove a demo car equipped with Mps suspension and it rode better than my 2018 on bad roads.

I latter test drive my friends car on track with Mps suspension and it was much much better than mine.

I then ordered Ohlins

Anyone do a direct comparison to Bilstein B16?
Seems like that setup might be more comfortable on the street.

There is a thread around here somewhere.

In a nutshell: both are comparable in quality of ride to each other. Which is slightly stiffer than OEM.

Ohlins is of higher quality and of course price than Bilstein (due to its "monotube" design with better heat dissipation)

Just curious did you go with true Coilover in the rear with the motion control Coilovers ?
