DBA42397XS

Feature Description	Advantage	Benefit
Kangaroo Paw – 144 diamond and tear drop pillar ventilation system	Increased surface area resulting in greater heat dissipation	Minimises brake fade and increases braking effectiveness
	Increased surface area resulting in greater heat dissipation	Prolongs service life for both pads and rotors. Reduces mechanical damage and associated costs
XG150 High Carbon Alloyed Iron	An increase in thermal capacity property allows the rotor to handle constant extremes of heat over extended periods of time	Minimises warping and cracking and prolongs the service life of the rotor
Paint protection on non-friction areas	Reduces corrosion	Stops any unsightly rust formation
	Enhances appearance	Adds value to the product
CBN (Cubic Boron Nitride) machine turned	Reduced DTV (Disc thickness variation) and parallelism	Less occurrence of brake shudder or brake pedal

Ideal for enthusiasts looking for an upgrade over stock rotors.

Premium non-directional cross-drilled and slotted design of DBA brake rotors increases the number of outgassing exit points allowing more brake pad friction gasses to escape through.

Brake rotors from DBA Street Series feature with "Kangaroo Paw” – 144 diamond and tear drop pillar ventilation system. Increased surface area results in greater heat dissipation and thus minimises brake fade and increases braking effectiveness of disc brake. CBN (Cubic Boron Nitride) machine turned reduces DTV (Disc thickness variation) and parallelism which brings less occurrence of brake shudder or brake pedal ‘judder’.

While providing a similar performance benefit to the T3 slot, the 4000 XS Series is a popular alternative for open wheel and show cars. We recommend the T3 slot design for more intensive braking applications.
