4 series m performance bbk fit our cars?

May be a dumb question but would these fit our cars? Specs seem almost the same and would benefit from a real 4 pot bbk for $1900.

Fronts are 10mm larger. 370x30 vs 360x30

Thoughts?

My thoughts, exactly--especially the carbon setup.

That would very likely create brake bias issues, and overbraking the rear is extremely dangerous because if the rear locks up before the front, you have a very unstable situation. In fact even retrofitting the front and rear together might cause issues if the master cylinder sizing is significantly different between our M3 and the F32, to say nothing of the DSC retrofit that's virtually guaranteed not to be available for our cars with this kit. I agree the price is highly appealing especially given that it includes front and rear (but no rear rotors?), but I'd be worried about issues, and brakes aren't something you just throw caution to the wind on.

I believe OEM and aftermarket rear calipers on our cars also need to be tweaked to accommodate the parking brake, in which case front calipers on the rear won't work.
