That's not far from what I'm running on the OG (0.05, 1.8 and 0.10, 1.6)

How does the M2CS achieve 1.8 degrees of camber? I thought the M2 and M2C were limited to 1.5 without camber plates or hubs. Ive seen ~1.8 is achievable with the added camber from lowering ride height, but the CS is noted to be about the same height as previous F87's.

If that 1.8 is true on the M2CS you can achieve that by adding Camber hubs and keep stock height.

Keeping stock height with camber hubs gives between 1.7-1.8 neg camber. Lowering with camber hubs (like I have done) you can end up with 2.2 neg "fixed" camber with the correction hubs.

But that's just static camber. Depending on travel you may have no more dynamic camber which is the bit that actually counts. So you may just be wearing out your inner tyres and introducing annoying steering. File under the many reasons why I hate lowering springs. If you have a proper coil over setup, properly corner weighted and properly aligned then disregard this post.

Coils, camber correction hubs, M2CS Racing roll bars, front thrust arm Millway uniballs bushes and full geo/corner weighted with me in drivers seat (127kg)

Do it right or not at all

But, my car is actually going under surgery at Litchfield Motors, removing M Perf coils and fitting Nitron's

MPerf coilovers + OEM -0.5deg hubs, Bimmerworld UCA/TS monoballs and fully fettled & setup at Center Gravity.

I didn't see it mentioned anywhere that the CS had the camber correction hubs and wanted to confirm that was how it hit the 1.8.
Enjoying the insight on this thread. I was interested in avoiding the added NVH of camber plates; starting digging into alternatives for more camber and I ended up here.

Not sure if they have a product for the f87 platform, but Vorshlag camber plates did not increase NVH at all on my e82 and definitely improved steering feel due to the pillow all mount and massive rotational bearing. There is no play at all, hence no noise.

I have heard that GC plates can cause some rattle.
