Description:
EVANNEX engineered 2-Piece semi-floating rotors that offer real-world benefits which can be felt on both the street and track! Our 2-Piece rotors combine the advantages of weight savings and rapid heat dissipation to provide a rotor superior to stock while preventing warping and extending component life. The reduction of unsprung weight improves handling characteristics under all situations. This reduction in rotational inertia allows for quicker acceleration, decreased braking distances, and more responsive handling.

Aluminum hats: To save weight, each rotor ring is bolted to a lightweight aluminum hat made from high-quality 6061 aluminum, and hard anodized with an attractive matte black finish that is both durable and corrosion resistant.
-
Gray cast iron rings: Long known for its wear resistance and stable friction characteristics, cast iron is favored for brake rotors due to its ability to absorb and dissipate large amounts of heat.
-
2-Piece construction: Conventional rotors are unable to cope with the stress of drastic heat fluctuations and are prone to warping. EVANNEX 2-Piece semi-floating and full-floating rotors allow the radial expansion of the rotor ring - preventing warping.
-
Heat-treated: Heat treating further reduces the tendency for rotor cracking by reducing internal rotor stresses.
-
Directionally veined: EVANNEX 2-Piece rotors feature directionally curved veins. Directional vanes accelerate air away from the rotor at a higher velocity, leading to consistent, rapid cooling on both sides equally.
-
Slotted: EVANNEX Slotted 2-Piece rotors are slotted to clean brake pads and carry away water and brake dust. Slotting reduces the effects of pad glazing that often results from extremely high temperatures by continually cleaning the pad surface, resulting in more consistent stopping. Slots are machined with a ball end mill to prevent cracking that may be present on improperly machined rotors.
-
Manufacturing quality: Non-friction ring surfaces, including internal vents, are painted to resist salt and other corrosives. Ground braking surfaces ensure rings run parallel, and pads bed easily.
Highlights
Semi-floating design reduces heat transfer from rotor to hub
Slots even out wear across the brake pad faces, increasing the effective contact area and extending rotor life.
Reduction in rotating mass and unsprung mass means greater efficiency and higher performance
Design:
Light-weight anodized 6061-T6 aluminum inner hat
High-strength GEOMET-coated FC-30 cast rotor ring
Rear rotor: 365mm diameter and 28mm thick
What is the difference between semi-floating and full-floating rotors?
The primary difference between semi-floating and fully floating rotors lies in their heat management approach. Fully floating rotors maximize heat isolation from the hub by separating the hat from the rotor using floating hardware. The 2-piece design allows the rotor to expand and contract through heat cycling on and off hard braking, which greatly reduces the opportunity for cracking on the rotor surface. Semi-floating rotors share this heat expansion benefit!
