The M Performance suspension was developed with M engineers on racetracks. It will be 10mm lower than M Sport package suspension. It will be stiffer than M Sport for better handling.

The M Perf setup will have higher rate/firmer springs for sure.

I'd like to know the difference between the M Performance dampers, sport line/Msport dampers, and M adaptive dampers, in relation to using the M Perf springs with either the sport suspension, or the M adaptive sport suspension.
Damper tuning goes hand in hand with spring rate, so M Perf dampers will be dialed in to handle the firmer and shorter spring.

But, what if someone with the standard sport/Msport suspension were to add the M Perf springs? Likely the ride will be firmer, but will there be too much spring for the standard sport suspension dampers?
My guess is that, yes, the car may be over-sprung and under-damped.
But, maybe not. Maybe the stock sport damper is capable of handling the M Perf spring. I'd like that question asked.

Also, same goes for the M adaptive dampers. My guess here is that the M adaptive damper should work fine with M Perf springs, considering the wider and self adjusting nature of the adaptive dampers.
I'm interested in possibly installing the M Perf springs on my Msport, which has the M adaptive dampers.
This should give a firmer all around ride, and firmer control when the adaptive is set to "sport".
