I understand the front brake pads for the Roadster are Z4M pads but can anyone confirm whether the calipers are also the same used for the Z4M?
Thanks
Alpina Roadster Brake Calipers
On the Z4's there are 3 differing Disc Sizes and the callipers would vary to match the radial I would imagine.
2.0-2.5L Z4's have 286mm Discs
3.0L Z4s have 300mm Discs
Z4ms have 345mm Dics
I know you asked about the calliper, not the disc, but this may help.
I thought the front Alpina Roadster brakes were taken from the M3 whilst the rears were standard 3.0 discs, but dont quote me.
