Master cylinder compatibility

I am looking at purchasing the BMW 34112450468 M performance kit which includes the following for my 2010 E89 3.0. I have 18" wheels already. My question; Is the caliper set compatible with the stock master cylinder 25mm front bore and 22mm rear bore. The stock E89 pedal travel is already too long and I don't want to make it worse. Has anyone changed MC's and if so which one did you use?


370x30 mm discs[/I] with 4-piston-calipers (for min. 18" wheels):

4-piston-calipers yellow: 34106855475 + ...6
4-piston-calipers red: 34106855477 + ...8
4-piston-calipers orange: 34106855479 + ...80
discs 370x30 mm (perforated): 34106797603
dust cover: 34116792237 + ...8
brake pads: 34116859066


The 370 mm BMW Performance brakes are the better solution for upgrading the Z4 than the 340 mm and the only possibility for Europe to get a legal p&p solution for the 35i/35is.
