Floating versus Fixed Brake Rotors

[bimmerboxer]

Hope to get some advise.
Am looking to replace my rotors with after markets. Budget is always a concern without compromising on safety and performance.

Found a sleek pair of fixed Discs for the 1150 GS.

An easy 5 bolt job per disc.

This versus the Grimecas which require you to mount it with the carrier, new bobbins, dished washers and e-clips.

Ignore last post. I mistook the RS (97) and GS (2002)to have similar brake configurations.
One uses a carrier requiring bobbins and such whereas the GS does not.

Cheers
