BMW Performance brakes

[VerySideways]

Noticed in the BMW Performance catalogue that there is a brake kit for one and three series - 6 pot fronts, 2 pot rears, discs and pads.

I hear it's £1100 for the parts, £1500 fitted (inc VAT), but has anyone done this yet??

I fancy the kit but would like to know if anyone has some feedback on it first...
