Radial Master Cylinder

The front master cylinder on my 02 S3 is thrashed. Going to upgrade to a brembo or nissin radial soon. Wanted to see if anyone out there has had good or bad with either one and a good recomendation for bore size. Any help would be appreciated.

Get one off a late GSXR - 06 1000 has it
Pick up on EBay for < $100.

Note: the radial lever is different (because it's radial, not because it's Suzuki) so you will need the lever to match.

Or buy a D675 MC. Costs about $170 at bikebandit.com
