RacingBrake Two-Piece Front Rotor Drilled and Slotted Subaru WRX 02-05
RacingBrake rotors are engineered and manufactured to meet the needs of the performance enthusiasts. From 3D CAD design to tooling development, casting, machining, and surface coating, RacingBrake controls all production processes to insure the quality, performance, and value.AdvantagesLighter rotor (12-16% weight reduction varied with the size and design) than original one-piece rotor - meaning lower spinning weight.Cooler disc - due to higher heat dissipation rate of aluminum hat as compared to cast ironTrue full sliding design (unlike others out in the marketplace) allows the disc to expand and contract freely without stressing the hat. This helps prevent the disc from warping or cracking.Allows consumers to replace only the rotor ring, while reusiing the hat. Although the initial cost of two-piece rotors is higher than one-piece rotors, the lifetime operating cost could be lower.Material:
Alloyed iron formula adds strength and heat resistance. Heat treating further improves rotor performance for a more uniform and stabilized microstructure.Design:
The cooling vanes are of a convergent nozzle design, which increases airflow and turbulence and makes discs cooler. This can be viewed in Illustration #1.
The center-mount flanges for hat mounting to the rotor ring have several benefits. Illustration #2 for referenceIt allows the ring to be used on either side of the vehicle simply by mounting the hat on either side of the ring (unidirectional).The stress load transferred from the ring to the hat is balanced. Air inlets are widely open to both inboard and outboard sides of the rotor. More air suctions and even temperature on both sides of the disc surface. Heat transfer from the disc surfaces to the hat is even and minimized by increasing the flange length and the airflow around the flanges. Mounting flanges are on both friction surfaces ultimately provides excellent heat balance.
Exclusive full floating design with 10.9 grade alloyed hardware. Hardware is DACRO coated and crimp locking. DACRO is highly corrosion resistant and provides a film for easier movement between the hat and rotor ring as disc expands and contracts and the crimp design provides positive engagement without rattling or torque loss at temperature.
