Sounds like there's some conflation over ride comfort vs handling. Some are commenting that the M2c handles better than the M2. It should, it's been stiffened up more in front as well as well as having the steering and MDM remapped.
The other side of this is ride comfort, some say that the M2c rides the same while others say they notice it's a bit smoother than the M2.
What we know:
- M2 and M2c suspension components are all identical and have identical part numbers.
- M2c weighs more than the M2.
- M2c front is stiffer with the added bulk head brace and CFRP strut brace.
