What is the benefit of the slotting on these rotors?

The slots help to evacuate brake dust, gases, and heat away from the pad and rotor surface. This prevents glazing, maintains a cleaner pad surface, and leads to a more consistent and improved initial bite in both wet and dry conditions.

How does the E-coating protect the rotor?

The black E-coating is applied to the non-friction surfaces of the rotor. It acts as a protective layer against rust and corrosion, helping to keep the rotor looking good and preventing premature wear on those areas.

Are these rotors quiet during operation?

Yes, the high carbon metallurgy used in these rotors, in most applications, is designed to offer quieter operation. This is especially beneficial when paired with higher friction brake pad compounds.

Product Details

If you're looking to get more out of your MDX's braking system, especially when pushing it a bit harder or dealing with wet conditions, these Stoptech Slotted Sport Rotors are a solid choice. They're designed as a direct replacement for your factory rotors, meaning they fit right onto your stock calipers and mounting points without any fuss. The unique slotting pattern isn't just for looks; it plays a key role in how your brakes perform.

These slots help to sweep away brake dust and gases that can build up between the pad and rotor. This keeps the pad surface cleaner and prevents glazing, which means you get a more consistent and stronger initial bite, whether you're braking in the dry or the wet. The rotors are also treated with a black E-coating to protect them from rust and corrosion, and the high-carbon metallurgy helps reduce noise and resist cracking under thermal stress, making them built to last.

For your 2007-2013 Acura MDX, these rotors offer an improved braking feel and performance over standard discs. They pair well with many types of brake pads, especially European-style compounds that can benefit from the increased bite and heat management these rotors provide.
