4000 Series Standard Brake Rotor

The DBA 4000 Series Standard Brake Rotor is engineered by Disc Brakes Australia (DBA) for drivers seeking performance braking upgrades beyond standard equipment. Constructed from high-carbon alloyed iron, these rotors undergo Thermal Stability Profiling (TSP) to ensure they can withstand the intense heat and stress generated during demanding braking applications. This specific model, DBA42700, is a vented rotor designed for the front of select vehicles. It incorporates DBA's unique Kangaroo Paw ventilation system, which utilizes 144 diamond and teardrop-shaped pillars. This innovative design provides up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs, contributing to consistent braking performance and longevity. The DBA 4000 Series Standard Brake Rotor is compatible with the 2003-2009 Lexus GX470 and the 2003-2009 Toyota 4Runner. For the Toyota 4Runner, it is specified as a 338mm front disc that fits with the Front Caliper Casting# 13WH.
