The rotors are built to the factory rotor spec and install with the factory caliper when the front caliper is a fixed design and the rotor spec matches. The included pad shape matches the OEM pad shape. If the car uses aftermarket calipers such as Brembo, AP Racing, Alcon, or Wilwood, provide the exact caliper model and StopFlex can supply the matching pad shape. Direct replacement is not confirmed if the front caliper is floating, or if the car already runs a non-OEM-offset rotor and the actual rotor dimensions cannot be supplied.\u003c\/p\u003e\u003c\/div\u003e\u003c\/section\u003e\u003csection class=\"box\"\u003e\u003ch2\u003eWhy StopFlex CCB\u003c\/h2\u003e\n\u003cdiv class=\"grid g3\"\u003e\n\u003cdiv class=\"card\"\u003e\n\u003ch3\u003eLightweight\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eHalf the Weight, Sharper Handling.\u003c\/strong\u003e StopFlex carbon-ceramic rotors shed roughly half the mass of equivalent iron discs.
