Using radial-mounted fixed calipers together with oversized discs gives the system greater braking torque and superior thermal capacity. The result is a braking action that is noticeably more immediate and decisive even in normal road usage, and is extraordinarily powerful and consistent under the repeated loads of track use.

Fixed calipers improve the durability and efficiency of the system: the opposed multiple pistons act on the pads with more precision, due to the smaller piston diameter and the reduced pressure exerted on each individual piston, while the greater overall surface area between the pads and pistons results in more uniform friction surface wear. The superlative stiffness of the calipers and the metal braided hoses reduce brake fluid absorption. The result is improved, more stable brake pedal pressure, making it possible to modulate braking force more precisely and enhancing pedal feel.

Featuring a hat in aluminium alloy, the oversized floating disc system reduces unsprung mass (for improved handling) and thermal stress. The mounting system is engineered to permit a greater degree of both radial and axial float.

This characteristic, together with the greater dimensions of the braking rotor surface, improves the dispersion of the heat generated by the repeated, intense thermal stress that the discs are subjected to, for consistent braking performance and pedal feel even after numerous laps on the track.
