Marylandspeed is excited to introduce DBA's new T3 Clubspec 4000 series line of rotors. These new rotors replace DBA's prior 4000 series slotted rotors. The new T3 design has several benefits including improved ventilation, better casting, and they are now no longer side specific like the old wiper slotted rotors. They also are reportedly quieter, and still include DBA's Thermo Graphic heat paint, which changes color as certain brake operating tempatures are reached. This is bar none the best OEM replacement rotors you can buy for your GTO.

DBA Product Information-

CLUBSPEC is the new product category for DBA’s performance enhanced disc brake rotors. These are the ultimate in road and race brake rotors, featuring a number of performance enhancements.

Through extensive testing and feedback from performance drivers worldwide, DBA has developed a unique cast iron formula (XG-150) for use in all of it’s CLUBSPEC disc brake rotors. The XG-150 formula, with it’s increasedthermal capacity properties, is designed to respond to the DBA TSP process allowing the rotor. to handle constant extremes of heat over an extended period of time.

TSP™ is a process of relieving the stresses that are naturally generated in the casting and manufacturing processes. This process stabilises the stresses by re-aligning the microstructure of the iron, resulting in a disc rotor ideal for heavy road braking and race applications. Unlike standard pillar rotor ventilation designs, the patented ‘Kangaroo Paw’ system features a series of 144 individually spaced diamond and tear drop shaped pillars. The design also works on the same principal as an air-impeller which actually pumps air regardless of the rotor’s rotational direction. As a result, the rotor cools faster and maintains braking efficiency for longer periods (Patent No. 742353)

All CLUBSPEC series rotors incorporate DBA’s Thermo-Graphic heat paint markings which change colour at specific temperature thresholds. This offers the driver a clear indication of the peak temperatures the rotor has been subjected to.
