Here's what M2 project manager Frank Isenberg said at the end of 2015 about the M2 tires, suspension and brakes:

"That chunkier body - 55mm wider front, 80mm rear - is essential to cover wider track courtesy of M4 forged aluminium suspension components. «The track is the same, but the M4 tyres wouldn't fit, so the tyres are 10mm narrower,» says Isenberg. The Michelin Pilot Sports measure 245/35 ZR19 front, 265/35 ZR19 rear.
The suspension is matched to bespoke springs and dampers but there's no adapative suspension. «The problem with adaptive dampers is you're changing the damper, not the spring, so you end up with a spring that is a compromise between two settings,» explains Isenberg.
Underneath the M2's squat body, additional bracing increases rigidity. «Boomerang braces» arc between headlamps and front wings, struts angled at 45 degrees glint through both kidney grilles like a rollcage through a rear window, and both the A-pillar and boot also sent for reinforcements.
The M4's optional carbon-ceramic brakes aren't offered, engineers arguing that the cost, plus the reduced power and weight of the M2 negate the need. Instead, regular M4 brakes are carried over - drilled discs all round, four-piston calipers front, two-piston rear - and you can ask your dealer for track pads; there's no performance increase and they squeak, but the last longer."

Riding a horse: just one setting and that's it. It's just a matter of getting a good horse.
