FNSLR/ST forged billet calipers, with four Thermlock pistons, deliver championship proven performance with piston sizes to provide matched rear braking bias for use with the Aero6/ST or other larger piston front calipers. FNSL4R/ST calipers incorporate race technology into a radial mount body design with widespread adaptability. Including competition update options for all FNSL4R rear Big Brake kits. Thermlock pistons, high-temp seals, SRS bridge plates, and two-piece bleed screw assemblies are standard in all calipers. Four high-temp race only brake pad compounds in the 7416 pad type allow precise tuning of the brake response, friction requirements and temperature range.

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only.
