Light on weight. Long on looks. ECS Tuning 2-Piece 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; non-braking surfaces painted for good looks and corrosion resistance.

Reduce weight. Reduce heat. Reduce warping.

ECS Tuning engineered 2-Piece semi-floating rotors offer real world benefits that 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 25% reduction of unsprung weight by (7 pounds per rotor) improves handling characteristics under all situations. This reduction in rotational inertia allows for quicker acceleration, decreased braking distances, and more responsive handling.

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 veined: 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 veins 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 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 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.

Testing:

• Our rotors 2 piece rotors have been subjected to thousands of miles of hard street use and to the elements (including snow and salt) for years. They have also been subjected to scientific brutal stress testing at the track, performing countless high speed stops in quick succession. We have measured stopping distances and elevated rotor temperatures of over 1000*F for long sustained periods (to the point of rotor bluing and catching brake pads on fire), as well as subjecting rotors to careful post-test inspection for signs of irregular wear, warping, stress cracking, or any other signs of failure.
• Our rotors have proven themselves to be robust, demonstrating excellent wear characteristics, no warping, no thermal stress cracking, no signs of hot spots and minimal pad glazing.

I want something like this for my 2001 Audi TT, front rotors! Something lighter weight than stock rotors

 

We did have stock sized 2 piece rotors at one point but we no longer carry them.

We have a stage 5 big brake kit that utilizes Porsche calipers and a 2 piece rotor available below!
