Has anybody found replacement slotted/drilled rotors for the gp2 brakes?

Mine has built up dust already and squeaks a lot during light braking, think slotted should help clean it up

 

I haven't seen any, and I think it is pretty unlikely to happen. It is a small market (2000 cars only) and the rotor is unique to this car. By comparison, the pads are common to the 135 and BMW sports brakes and there are lots of options

 

A little off topic, have anyone put stainless steel brake lines on their GP2 yet? I know the factory brake lines are different for GP2 compared to other R56s, so would something like the Goodridge Stainless Steels brakelines fit? Please share your experience.

 

On one of mine I used the HEL pre-made R56 kit and it fitted no problems. On the other car I used goodridge lines, but the guy came to the shop and made them specifically, it was not the pre-made kit.
