The Wilwood Superlite FNSL4R/ST forged billet caliper uses race-derived radial mount technology and four Thermlock pistons to provide matched rear braking bias when paired with Aero6/ST or larger front calipers. Standard features include high-temp seals, SRS bridge plates, and two-piece bleed screws; four 7416 pad compounds allow precise tuning of response and temperature range for track or competition use.
