It provides the highest available resistance to heat distortion, warping, cracking, and wear for competition applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: What is the difference between GTB and GT?\u003c\/strong\u003e\u003cbr\u003eA: The GTB version includes a black e-coat finish on the hat for improved corrosion resistance. The GT uses a standard hat finish. Rotor ring performance is identical.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: Is this a right-hand or left-hand rotor?\u003c\/strong\u003e\u003cbr\u003eA: The 160-13787-GTB is a right-hand (RH) rotor.
