The DBA Longlife slotted range offers additional durability and improved stopping power to Police and Ambulance vehicles as well as Courier Vans, Taxis and 4WD's. For the ultimate in braking performance, the DBA Longlife Gold series, featuring cross drilling and slotting, offer a level of technology expected only on high performance and exotic sports cars.

DBA Longlife Gold high-performance disc brake rotors have performed strongly in a series of tests conducted by respected advanced driver training figure Peter Finlay.
During the tests, at Oran Park near Sydney, a current series Holden Commodore fitted with the DBA Longlife Gold product averaged a theoretical efficiency of 97 per cent over a series of stops from 100 km/h.

It recorded a best stop of 38.6 metres.
The average stopping distance from 100 km/h was 40.4 metres. This compared with 42.6 metres (90.25 per cent theoretical efficiency) for the same car tested under similar conditions with standard rotors

Kangaroo Paw' is a patented hi-tech disc rotor ventilation system, designed and manufactured in Australia by Disc Brakes Australia.
The Kangaroo Paw design features a series of 144 diamond and tear drop shaped pillars and columns, individually spaced between the rotor faces. This system provides two key advantages.

One advantage of this design is the ability to cool the rotor faster than ever before. This works on the same principal as an air-impeller, designed to extract hot air.
As the disc rotor rotates, aerodynamic turbulence around the individual pillars and columns is generated, increasing the force of hot-air out from within the internal areas of the rotor.
The second advantage is the increased dimensional stability across the disc rotor, directly achieved by the individually spaced pillars and columns.
These advantages increase the disc rotor efficiency by as much as 20 per cent when compared to conventional rotor designs.
