Got this amazing 4 piston brake caliper from ISR (22-048-OC) that normally is fitted to 125cc bikes or lightweight cars such as Formula SAE cars. I hope the brake feel will be good with this setup.

This caliper has exactly the right bolt hole spacing (84mm) for the original caliper bracket from a Ducati 999, however the bracket and caliper needs to be milled back for everything to fit. Looks pretty as fuck on that Marchesini magnesium wheel!
