Here is my challenge to you. Find an aftermarket spring for this platform that is stiffer than OEM and isn't part of a full coil over setup and what the spring rate is.

Because so far what I have found so that all the aftermarket springs made for this platform are actually softer than OEM, and they can't even tell you the rates since they are progressive springs. And I understand it's a smart business move on their part since most owners don't track their car and they care more about looks and comfort.

My statement was made in general terms to counter the general erroneous statement made in the OP.

If I were you, I’d look at BMW’s own MP-HAS. I am not familiar with the G8X options since I don’t own one, but the MP-HAS provided a noticeably positive difference on my M4cs. I am sure BMW properly did their homework for the G8X as well.
