Scrub the speed off your street machine or race car with the iron grip provided by Disc Brakes Australia Rotors. These performance discs deliver a serious upgrade to any braking system on the road or the track. Featuring T3 4000 Series Rotors, T2 Slotted Rotors, Gold Series Rotors and more, they maintain constant friction for a cleaner disc surface and less fade.

Thermo-Graphic heat paint is marked on the edge of each rotor. The colors change to signify temperature thresholds, making quick work of monitoring rotor temps. Rotors also feature DBA's Thermo Stability Profiling which handles the higher temperatures that result from spirited driving.

To keep your rotors cooler than a can of Fosters, DBA uses a "Kangaroo Paw" vent design. The vents work like an air impeller to quickly extract the hot air. It also produces a rotor that's 20% more efficient than traditionally vented discs. And best of all, DBA backs your rotors with a 12-month, 12,000-mile warranty.

Frequently Asked Questions

Whats the advantage of two piece rotor?
Two piece rotors are far lighter than their single cast counterparts. They also allow better heat contraction of the rotor ring, and in some cases better air flow through the rotor for better heat dissipation.

What's the advantage of a slotted rotor?
The basic idea is to vent gas away and renew the pad surface to prevent pad glazing which could otherwise have a negative affect on performance.

What's the warranty?
1 year or 12,000 miles whichever comes first.

Can I turn or resurface these rotors?
Sure, you can turn or resurface these rotors as long as they are still within their minimum thickness specification, noted on the perimeter of the rotor. We don’t recommend turning rotors unless you absolutely don’t have another choice. You lose thermal capacity making them prone to "warp" again that much sooner, plus the hassle of the labor involved to remove the rotors in the first place with no guarantees of a "fix".

Are the rotors balanced?
Yes, they are balanced to ensure smooth operation and rotation

We guarantee a perfect fit
  • Kangaroo Paw venting is not available on all part numbers.
  • Rotors should always be replaced in pairs (front or back). Replacing a single rotor leads to uneven pad wear, steering pull, and ultimately, costly damage. Single rotor replacement is highly discouraged.
