How do the slots on these EBC rotors help my brakes?

The progressively angled slots on these Ultimax rotors help by pulling in cooler air to keep your brakes from overheating. They also sweep away brake dust and debris, which helps maintain good pad grip and can extend pad life.

Are these rotors a direct replacement for my stock Mazda RX-7 front rotors?

Yes, these are designed as a direct fit replacement for the front vented rotors on your 1979-1983 Mazda RX-7. They match the original specifications for diameter and thickness.

Do these rotors come with hardware or are they sold separately?

This listing is for the brake rotors only. Installation hardware, such as lug nuts or brake pad hardware, is typically sold separately. It's always a good idea to inspect your existing hardware during installation.

Product Details

If you're working on your 1979-1983 Mazda RX-7 and need new front brake rotors, these EBC Ultimax slotted rotors are a solid option. They're designed to fit your specific RX-7, replacing the stock vented rotors with a similar setup but with added benefits from the slotting pattern.

What's neat about these Ultimax rotors is how EBC engineered the slots. Instead of just straight cuts, they use progressively angled slots. This design helps pull in cooler air to keep your brakes from getting too hot during hard stops, which means more consistent braking. The slots also do a good job of sweeping away brake dust and debris. This not only helps your brake pads maintain maximum grip but can also extend the life of your pads by preventing buildup.

These are vented rotors, meaning they have internal passages to help dissipate heat. They have a 228mm diameter and are 18mm thick, matching the original specifications for your RX-7. They come ready for a direct fit installation, so you can get back on the road with improved braking performance.
