The CS rear tire is the same 285/30R20 size as the Competition pack, which is just 5mm taller than the 275/35R19 or 4mm taller than the 275/40R18.

Any idea how much firmer if this is indeed the case?

Any feedback on this?

Now that we know the M3 CS is on base springs, what would we expect from MP HAS from an increase in firmness? If at all.

Bump, any update ?

Wow I wonder how the CS would handle on zcp springs...interesting how I hear it’s firm, yet it’s on the springs with softest rates...

It would probably roll less but the fine balance and feel wouldn't be good, and it may not be as balanced and linear at the limit. Each version of the F8X uses a different mix of springs, bars, and damping to achieve its balance, and mixing/matching components will throw the balance off. That's why people say the car understeers when the code the CS edc cal into their base or EDC car.

Anyone know the spring rates of the CS springs from the factory?

Want to compare them to the eibach euro v1 or even v2s

I have the MP HAS kit inbound for my 2019 M4CS. Interesting that the MP HAS isn't listed for the CS, I don't feel good altering the suspension at all since it's so dialed in by the factory but I've heard good feedback from other CS members with the HAS.

KW manufacturers the MP HAS kit and they have their own KW branded HAS kit which is listed as compatible, so I wonder why BMW hasn't listed the CS with their HAS kit.
