The DBA Rear 4000 Series Plain Rotor is a high-performance brake component designed for enhanced stopping power and durability. Crafted from high-quality materials, these rotors feature a plain finish that reduces weight and improves heat dissipation during aggressive driving. The 4000 Series rotors are engineered to provide consistent braking performance, making them suitable for both street and track use. Their robust construction ensures long-lasting performance under demanding conditions, offering improved fade resistance and reliable operation. These rotors are an excellent upgrade for drivers seeking improved braking response and durability from their vehicle's braking system.
Designed specifically for the Toyota Supra models from 1993 to 1998, these rear rotors serve as direct replacements for stock components. While fitment may vary depending on the brake package, users are advised to measure their existing discs and compare with DBA specifications for optimal compatibility. These rotors are intended for street and performance driving, providing a reliable upgrade over factory units. Installation is straightforward as a bolt-on replacement, and the kit includes the necessary rotors for the rear axle. They are suitable for enthusiasts looking to improve braking performance on their Supra during daily driving or spirited driving sessions.

DBA's 4000 Series disc brake rotors are a direct replacement single-piece brake rotor, designed for drivers seeking upgraded performance braking in the Specifications tab and beyond standard OE levels. Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), DBA's metallurgy is able to handle the increased stress and heat generated under intense braking applications, time and time again.
Featuring DBA's patented Kangaroo Paw ventilation that implements a series of 144 diamond and teardrop patterned pillars, DBA achieves up to a 30% increase in surface area and 20% improvement in cooling efficiency (as compared to a traditional straight vane design).
DBA's 4000 Series HD variant features a smooth OE style rotor finish, popular for drivers looking for the benefits of a 4000 Series rotor but requiring an OE style look, such as under controlled race divisions.

Features (Where Applicable):
Kangaroo Paw 144 diamond and tear drop pillar ventilation system
- Increased surface area resulting in greater heat dissipation which minimises brake fade and increases braking effectiveness and prolongs service life for both pads and rotors. Reduces mechanical damage and associated costs
XG150 High Carbon Alloyed Iron
- An increase in thermal capacity property allows the rotor to handle constant extremes of heat over extended periods of time which minimises warping and cracking and prolongs the service life of the rotor.
- Special formulation designed to respond to DBA's TSP process.
Thermographic Temperature Monitoring
- Heat paint markings change colour at specific temperature thresholds offers the driver a clear indication of peak braking temperatures.
- When temperature thresholds are exceeded paint markings will permanently change colours allowing the driver to monitor rotor fatigue and decide on rotor replacement and to assist resellers with warranty claims.
Paint protection on non-friction areas
- Reduces corrosion, enhances appearance, stops any unsightly rust formation, adds value to the product.
