DBA DBA42028SR Front 4000 Series Slotted Rotor 2008 2009 Pontiac G8 GT

After decades of design and development with race teams around the world Disc Brakes Australia developed a proprietary cast iron ( XG-150 ) for use in all of it's premium performance disc brake rotors. This specially formulated iron is rich in carbon and alloyed to produce excellent thermal characteristics which is a key factor in the production of the casting combined with our patented Kangaroo Paw ventilation design. With it's supersaturated solution of carbon in an iron matrix the excess carbon precipitates out in the form of graphite flakes. The morphology of these graphite flakes provide excellent thermal properties increasing the thermal shock resistance and allowing it to survive rapid thermal cycling with core-heat levels of approximately 700oC and above.

Coupled together with DBA's TSPTM process where the cast iron is stress relieved during the manufacturing process you end up with a cast iron structure ideal for heavy braking and perfect for motorsport applications.

T3 Slotted Rotor

Features :
* Patented 'Kangaroo Paw' ventilation design* provides greater heat dissipation
* XG150 High Carbon Alloyed Iron increases the thermal capacity properties of the rotor over the T2 material
* Tri-Symmetrical T3 Slot design dampens the vibration harmonics resulting in a quieter responsive and a further improvement of brake pedal feel when compared to the T2 slot design. The T3 slots also provide rapid brake recovery after exiting water crossings.
* TSP (Thermal Stability Profiling) prolongs the service life of the rotor. This process is only applied to HEAVY DUTY T3 4X4 and CLUBSPEC rotors containing XG-150 high carbon alloyed iron
* Paint protection on non-friction areas enhances appearance

Notes

This is the passenger side front rotor only! The corresponding driver's side rotor is 42028SL.
