BRAKES

[Mr Tidy]

I doubt it - mine aren't drilled or grooved.

 

[M1k3yC]

Mine aren't either, and they were recently replaced at a dealer. I have an E86 3.0si Sport.

Nope, pretty sure that none of the Zeds have drilled and Groved discs, as standard.

 

[Ed Doe]

100% not original - only Ms have drilled discs as standard, all other discs for the z4 are plain.

 

[Silverzedtom]

As above, only the M variants came with drilled discs from the factory.

These look like Mtec discs judging by the pattern of the grooves
