The auxiliary sliding caliper is for the Parking Brake which is Hand operated (rather than foot or electrical) and is quite sketchy TBH. It has absolutely nothing to do with Hill Start Assist (my road V12 Vantage doesn't even have that function).

What was the reason for them ditching the drum style parking brake? Was there some EU regulation that mandated it be electrical or is this just one more gimmick that other manufacturers were doing and BMW didn't want to be left behind? |
Smaller Hat = more available space to increase the annulus without a corresponding increase in disc diameter. Reduces the unsprung mass by eliminating a secondary brake system on the rear axle and moves the rotational mass closer towards the axis of rotation.
G8x rear discs are the equivalent of a 405mm diameter rear disc on a F8x but have better cooling properties and only 380mm OD.
