Another new addition to our shop here, these are the same rotors used by MX-5s racing in the IMSA Continental Tire Sports Car Challenge.
These come as a pair of rotors and hats, fully assembled with all hardware, ready to bolt on.
These motorsports-grade, 2-piece floating rotors are direct replacements for the standard 2006-2015 MX-5 rotors, and work with the OE calipers.
2-piece floating rotors are dramatically superior to cheaper one-piece rotors for performance/track use. As the rotor temperature increases, a one-piece rotor will warp and migrate laterally - sometimes as much as a quarter inch one way or the other. 2-piece floating rotors stay centered even under extreme conditions, reducing brake drag and keeping the brakes operating properly and at lower temperature.
PFC Championship-winning race rotors feature benefits such as:
*More Stopping Power
*FEA Designed Thermal Capacity
*High Carbon Alloy with Molybdenum and Copper
*Extensive FEA Analysis
Performance Friction rotors are "dimpled" rather than slotted. Note that they are NOT cross-drilled:
