Light on weight. Long on looks. ECS Tuning 2-Piece front & rear brake rotors combine the natural advantages of a cast iron braking surface with the weight savings and rapid heat dissipation of an aluminum hat.
Cast iron-gray and durable matte black hats create an eye-catching contrast that accents painted calipers behind open-faced alloy wheels.
These beauties have all the extras: black anodized hats, cross-drilled and slotted brake faces, and unlike OEM, directionally vaned rotors for better cooling and heat dissipation over stock.
Features include:
- 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. ECS 2-Piece semi-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 vaned: Conventional S4 rotors are straight-veined, and rely on an inefficient centrifuge-like effect to evacuate hot air from within the rotor. ECS 2-Piece rotors feature curved, directional vanes that accelerate air away from the rotor at a higher velocity, leading to consistent, rapid cooling.
- Drilled and slotted: 2-Piece rotors are cross drilled to promote cross ventilation for even more improved cooling as well as slotted to clean brake pads and carry away water and brake dust. Cleaner brake pads result in faster, more consistent stopping. Drilled holes are chamfered while slots are machined with a ball end mill - both to prevent cracking that may be present on improperly machined rotors.
- Overall weight savings: This particular ECS 2-Piece rotor weighs only 18.6 lbs compared to a stock S4 rotor at 25.65 lbs. Lighter rotors reduce unsprung weight and rotational mass to improve both braking and suspension performance.
- 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.
