| The DBA Australia 350Z rotors are really nice parts. When ordering get the rotors for a 350Z track package. |
For rotors, we used some offerings from DBA Australia. We have had really good luck with DBA rotors on our Project STI in both track use and on the street. Part of the secret to the effectiveness of the DBA rotors is their patented Kangaroo Paw venting system. The Kangaroo Paw design is similar to the OEM Brembo pillar vane venting but has a twist. The DBA rotors feature a series of 144 diamond and tear drop shaped pillars and columns, individually spaced between the rotor faces that sorta look like a kangaroo paw. This system provides two key advantages.

| The stock front rotor is 11.7″ in diameter and 0.95″ thick. The DBA Australia 350Z part is 12.8″ in diameter and 1.2″ thick, quite a difference. |
One advantage of this design is the ability to cool the rotor faster than before. This works on the same principal as a turbocharger impeller, the vanes are designed to draw air through the rotor. As the disc rotor rotates, air is moved through the rotor by centrifugal force. Aerodynamic turbulence generated around the rotor’s individual pillars and columns helps improve the extraction of heat from within the internal areas of the rotor. When in Australia doing track testing with Whiteline, we collected data showing a rotor surface temperature drop of over 100 degrees on the track with the DBA rotor versus the factory part.

| The stock rear rotors are 11.5″ in diameter and 0.63″ thick. The DBA Australia 350Z rotors are 12.7″ in diameter and 0.87″ thick. |
The second advantage offered by the Kangaroo Paw rotor is increased dimensional stability across the disc’s friction face, achieved by the equally spaced pillars and columns. This helps reduce rotor warpage and pedal pulsation during use. These advantages increase the DBA rotor’s efficiency by as much as 20 per cent when compared to conventional rotor designs. A 20 per cent increase in disc rotor efficiency, translates to reduced brake operating temperatures, brake fade, disc rotor stresses, disc thickness variation, run-out and shudder.
