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.
Make your own conclusions.
Or BMW’s conclusion...

The engine compartment contains the most striking component: the CFRP high-precision strut brace from the BMW M3/M4. This one-piece brace made from extremely light, yet high- strength, carbon fiber weighs in at just 3.3 lbs. Together with the bulkhead strut from the M4, it significantly increases front section rigidity and improves steering behavior and precision.

The high-performance chassis utilizes the lightweight aluminum intensive front and rear axles from the BMW M3/M4. In order to ensure extremely precise wheel location, tight tolerance ball joints are used to transmit transverse forces. The control arms and wheel carriers of the new five-link rear axle are made from forged aluminum. A racing-derived rigid connection, dispensing with rubber bushings, is used to fix the lightweight steel grid-type rear axle sub frame to the body. This improves wheel location and tracking stability.
