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! 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.

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 of ECS 2-Piece rotors makes them stiffer and stronger - for improved performance and further prevention of warping. 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 20.95lbs compared to a stock rotor (24.45lbs). 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. Kit includes the following parts:

If your engine has higher mileage, don't neglect rod bearing replacement! These bearings are sandwiched between the connecting rod and crankshaft journal and are prone to failure due to overheating, lack of lubrication, or general wear. Replace your rod bearings and prevent a spun bearing.

Starting with ACL’s high-performance bearing shells, our Race Series bearings are built to withstand extreme RPMs and stress. Utilizing a "Duraglide" tri-metal construction and a high-strength overlay plate, these bearings offer superior oiling and heat resistance for high-RPM operation.

Our WPC-treated bearings take ACL’s already impressive design and enhance it even further. The WPC treatment process strengthens and smooths the bearing surface by firing high-speed, ultra-fine particles at the bearing shells, reducing friction and improving durability. This advanced surface treatment ensures smoother operation and improved heat dissipation, which are critical for any high-performance engine.
