DBA 42021XS Rear Slotted & Drilled 4000 Series Rotor for 2005 Pontiac GTO

Rear Slotted & Drilled 4000 Series Rotor

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 ectiveness 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.

• Increased surface area resulting in greater heat dissipation
• XG150 High Carbon Alloyed Iron
• Special formulation designed to respond to DBA’s TSP process
• Thermographic Temperature Monitoring
• When temperature thresholds are exceeded paint markings will permanently change colours
• Paint protection on non-friction areas
• Enhances appearance
• Prolongs service life for both pads and rotors
• An increase in thermal capacity property allows the rotor to handle constant extremes of heat over extended periods of time
• Heat paint markings change colour at specific temperature thresholds
• Allows the driver to monitor rotor fatigue and decide on rotor replacement and to assist resellers
• Reduces corrosion
• Adds value to the product
• Minimises warping and cracking and prolongs the service life of the rotor
• Offers the driver a clear indication of peak braking temperatures
• Stops any unsightly rust formation
• Reduces mechanical damage and associated costs
