Wilwood 160-12962 GT 48 Curved Vane Rotor – Left Hand

Genuine Wilwood GT 48 curved-vane rotor, left hand, as used in the 140-16093 big brake front kit for the 2006–2015 Mazda MX-5 Miata. Built for the extreme conditions of professional motorsports — the superior heat absorption and dissipation characteristics of these heavy-wall directional-vane rotors are key to preventing heat fade and realizing long service life from the rotors and pads.

Vehicle Applications

• Mazda MX-5 Miata 2006-2015
• BMW E46 M3 2001-2006
• Corvette C4 1988-1996
• Honda Civic 2006-2017
• Honda Civic 2017-2023

Cast from premium-grade, long-grain Spec-37 carbon iron for long wear, thermal stability, and resistance to distortion. Every GT rotor is fully detail-machined to eliminate stress points and unnecessary weight away from the pad sweep face. Faces and O.D. are precision turned to less than .001″ for flatness, parallelism, and run-out. The asymmetrical face slot pattern provides smoother engagement through reduced harmonics and improved thermal balance, and every rotor is individually dynamic-balanced for vibration-free performance at any speed.
