Built around AP Racing’s renowned \u003cstrong data-start=\"449\" data-end=\"496\"\u003eCP9660 six-piston forged aluminium calipers\u003c\/strong\u003e, this system delivers exceptional stopping power, superior pedal feel and outstanding thermal capacity compared to the factory braking system.\u003c\/p\u003e\n\u003cp data-start=\"641\" data-end=\"1201\"\u003ePaired with \u003cstrong data-start=\"653\" data-end=\"678\"\u003e378mm two-piece discs\u003c\/strong\u003e, lightweight aluminium bells and precision mounting brackets, the kit dramatically improves heat management and braking consistency during repeated heavy braking. The larger disc diameter and motorsport caliper design allow greater braking torque and fade resistance, making it ideal for high-performance road cars and track-focused builds. The CP9660 caliper is widely used in motorsport brake systems thanks to its excellent stiffness, low weight and consistent braking performance. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"1203\" data-end=\"1755\"\u003eCustomers can choose between \u003cstrong data-start=\"1232\" data-end=\"1310\"\u003egenuine AP Racing discs\/rotors or a more cost-effective aftermarket option\u003c\/strong\u003e.
