DBA’s 4000 Series XD brake rotor variants feature a non-directional
cross-drilled and dimpled rotor design and provide all the benefits of
4000 HD Series, but surpasses the HD spec in cooling benefits while at
the same time enhances the rotor's sports aesthetics.
The combination of dimples and drilled holes offers superior rotor
structural support compared to traditional cross-drilled techniques.
The majority of DBA's 4000 Series Brake Rotors boast the groundbreaking
Kangaroo Paw ventilation system. This system integrates a pattern of 144
diamond and teardrop-shaped pillars, yielding an impressive 30%
increase in surface area and a significant 20% improvement in cooling
efficiency when compared to conventional straight vane designs.
Additionally, all 4000 Series Brake Rotors are furnished with
Thermographic heat paint markings. These markings transition in color at
specific temperature thresholds, providing a valuable visual cue for
monitoring braking temperatures and evaluating rotor fatigue.
While the XD variants are an overall improvement over the 4000 Series HD
rotors, it's important to specify that drilled rotor configurations are
not advisable for intensive off-road or track day usage.
