This six-piston design pairs with fully floating 380x36mm race discs to maximise thermal efficiency and minimise fade during sustained braking events. The floating rotor architecture isolates heat from the hub, allows for free thermal expansion and reduces unsprung mass. Domed stainless steel pistons reduce heat transfer into the brake fluid and the increased caliper stiffness, combined with anti knockback springs translates to sharper brake response and improved modulation.

This four-piston design pairs with fully floating 380x30mm race discs to maximise thermal efficiency and minimise fade during sustained braking events. The floating rotor architecture isolates heat from the hub, allows for free thermal expansion and reduces unsprung mass. Domed stainless steel pistons reduce heat transfer into the brake fluid and the increased caliper stiffness, combined with anti knockback springs translates to sharper brake response and improved modulation.
