4000 Series T3 Slotted Brake Rotor

The DBA DBA42630S is a 4000 Series T3 slotted brake rotor, engineered by Disc Brakes Australia (DBA) for drivers seeking performance braking beyond OE standards. This direct replacement rotor is cast from high-carbon alloyed iron and undergoes Thermal Stability Profiling (TSP) to withstand increased stress and heat during intense braking applications. DBA's patented Kangaroo Paw ventilation system, featuring 144 diamond and teardrop-shaped pillars, is integrated into this rotor. This design offers up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane rotors, effectively reducing brake fade and enhancing braking efficacy. The tri-symmetrical slotting design contributes to a quieter, smoother brake pedal feel by decreasing vibration and noise, while also increasing out-gassing locations to improve brake stop uniformity and overall performance. This rotor is specifically designed for the front of 2007-2017 Jeep Wranglers with HEAVY Duty brakes and 332mm front discs. Its construction includes XG150 High Carbon Alloy Iron to reduce warping and cracking, prolonging rotor life. The rotor is coated for rust prevention on non-friction areas and features temperature monitoring paint to indicate peak braking temperatures. Key specifications include an outside diameter of 332mm, a vented design, 5 lug holes, and a high carbon rotor material. It is recommended for performance driving, including extreme and fleet duty, towing, performance street use, and track events.
