Sorry to burst the bubble a little here, I am informed that the diameter of the disc is the same on the front, slightly larger than the M Sports on the rear and the pistons are larger in the BMW performance units.

They are Inner-vented, lighter weight discs for more extreme driving and higher thermal factors.

They are Four-piston aluminium caliper on the front axle, two-piston aluminium caliper on the rear axle.
Available in M Performance Red, M Performance Yellow or M Performance Orange. Includes coloured M logo.
