Equipped with Brembo’s 30/34 staggered piston setup, the GP4-RB calipers provide a perfect balance of initial bite, progressive lever feel, and fade-free performance on the street or track. Finished in black with the iconic Brembo logo, these calipers combine factory race technology with a stealth look.
