ECS Tuning - 2-Piece Lightweight Front Brake Rotors - Pair (374x36mm) - ES#5340828

$1,055.99

Increase Cooling. Reduce heat. Go Faster. Stop Faster!

For enthusiasts in pursuit of maximum stopping performance, we've engineered direct bolt-on, two-piece, semi-floating brake rotors that offer real-world benefits on both the street and track! ECS two-piece rotors combine the advantages of weight savings and rapid heat dissipation to provide a rotor superior to OE, all while preventing warping and extending component life.

While the 8Y RS3 comes equipped with two-piece front brake rotors from factory, OEM replacements carry a steep price tag. To provide RS3 enthusiasts with a smarter solution, our engineers set out to develop a cost-effective alternative that outperforms the OEM design. 

Unlike the factory rotors, which feature drilled holes, ECS rotor rings utilize a precision-machined slotted surface. Slots provide consistent pad contact and superior debris evacuation, ensuring stable braking performance under repeated hard stops. Where drilled holes are prone to cracking under high thermal stress, slots maintain structural integrity, making them ideal for aggressive street driving and track use. The result is a rotor that combines durability, efficiency, and long-term reliability—all at a more attainable cost than Genuine Volkswagen/Audi. 

FEATURES

  • Constructed from heavy-duty 6061 aluminum, our lightweight, hard-anodized rotor hat design is both durable and corrosion-resistant.
  • Our two-piece design utilizes FC-30 cast iron—favored for brake rotors due to its ability to absorb and dissipate large amounts of heat.
  • The final product is heat-treated, which reduces the tendency for rotor cracking by reducing internal rotor stresses.
  • ECS two-piece rotors feature curved, directional veins that accelerate air away from the rotor at a higher velocity, leading to consistent, rapid cooling.
  • The slotted rotor ring design offers consistent pad contact, superior debris evacuation, and promotes efficient brake pad outgassing.
  • Non-friction ring surfaces, including internal vents, are painted to resist salt and other corrosives. Ground-breaking surfaces ensure rings run parallel, and pads bed easily.

PRODUCT DEVELOPMENT

Our Two-Piece, Semi-Floating Front Brake Rotors were designed, engineered, tested, and quality inspected by our Research and Development team at our Wadsworth, Ohio, facility. We strive for the highest level of precision and quality through leading-edge product development technology, including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

My part doesn't have a fitment guide.

We're so sorry about that, but we're working on it! We list over 100,000 SKUs and we're updating them daily. Some products are uploaded without the fitment guides being built out. If you're unsure about product fitment, please email us via support@exoperformance.ca.

  • How do I know if you have an item in stock?

    In-Stock Products

    In Stock

    Items marked as "In Stock" are physically in our facility, so they're ready to ship when the order is placed. If all items in your order are "In Stock", then your order typically ships within one business day.

    Other Availability Modes

    We use several availability modes to most accurately identify when products will leave their home facility:

    Direct Ship This product is available and will be sourced from one of our suppliers. It may take up to three business days before it ships.

    Warehouse Transfer We receive the item, then we ship it to remain on time with the guaranteed delivery range chosen at checkout. It typically takes between 6 and 12 business days before it ships.

    Discontinued - No longer available This product has been discontinued by the manufacturer and is no longer available.

  • How do I know if a part will fit my car?

    We update our catalog daily to provide the most accurate fitment information possible. When shopping for parts, please use the “select your vehicle” car selector on the home page. Once you've selected your car, you can filter parts specific to it.

    Additionally, on each product page, we have a tab for fitment information. By clicking on "Fitment", you can scroll and verify the part you are about to add to your cart indeed fits.

    Furthermore, if you have a vehicle added to our vehicle selector and you are viewing a product page, you'll see fitment information below the "add to cart" button. If an item fits your car it will display "This Part Fits Your: Selected Vehicule". If an item does not fit your vehicle a message will display "This Part Does Not Fit".

  • What is a core charge?

    A “Core Charge” is similar to the deposit you might pay for a can or bottle of soda. In many states, to promote recycling, you are charged a deposit when you purchase a can of soda and you receive your deposit back when you return the empty can. Many automotive parts have Core Charges that work the same way as a soda can deposit. The most common car parts that include a core charge are alternators, calipers, steering racks, and fuel injectors.

  • What is MAP pricing? Why can't I get a discount on a MAP item?

    "MAP" pricing, or Minimum Advertised Pricing, means that the vendor set a minimum retail price that we're not allowed to violate. MAP items cannot be discounted because the decrease in price would violate that threshold.
