What is the main benefit of the slots on these EBC rotors?

The wide slots on these EBC GD Sport rotors serve two main purposes. They help to sweep away dirt, dust, and debris from the braking surface, and they also help to dissipate heat more effectively, which reduces brake fade during heavy use or at higher speeds.

Are these rotors made in the USA?

EBC states that all their rotors are made from OE spec grey cast iron. Many of their rotors are British-made in their own UK foundry, and they specify that a majority of USA-specific designs are also British-made. When rotors are sourced from elsewhere to complete ranges, they are rigorously tested for material properties and runout.

What else might I need to install these rear rotors?

When replacing brake rotors, it's often recommended to also replace your brake pads to ensure optimal performance and to avoid damaging the new rotor surface. You may also need brake cleaner to clean the new rotor surface before installation and potentially new brake hardware or clips.

About this part

Product Details

EBC is known for making well-built brake components, and these GD Sport Slotted Rotors are a great example of their work. If you're looking to improve your braking performance, especially on trucks, SUVs, or vehicles used for towing, these rear rotors are a solid option. They're designed to help your brakes run cooler, which is key to reducing brake fade when you're carrying heavy loads or driving at higher speeds.

These rotors are made from OE spec grey cast iron, the same material used in new car production. The wide slots cut into the rotor surface are a notable feature; they help to sweep away dirt, dust, and debris from the braking zone. This not only keeps the braking surface cleaner but also allows heat to dissipate more effectively, contributing to that improved cooling and reduced fade. For domestic vehicles like your Chevrolet Blazer, S10, GMC Jimmy, or Sonoma, the rotors come with a black anodized finish for protection, while imports get a gold anodized finish. This rotor is designed for FMSI pad number D729 and features a vented design with 5 bolt holes, a 295mm diameter, and a 70.6mm center hole diameter.

This set fits a range of vehicles including the Chevrolet Blazer, GMC Jimmy, and Chevrolet S10. They are a vented, slotted rotor designed for the rear of your vehicle, offering a step up in performance and durability over standard OE rotors.
