Product Details
4000XD Series Dimpled and Drilled Rotor by DBA®. 4000 Series XD variant features DBA’s non directional cross drilled and dimpled rotor design. The XD finish provides additional cooling benefits above the HD spec, along with enhanced sports aesthetics. The DBA mix of dimples and drilled holes provides enhanced rotor structural support above transitional cross drilled techniques.
Features
- Painted non friction areas to prevent rust and enhance appearance
- Heat treatment cycles realign the microstructure of the iron, resulting in increased rotor stability and durability
- Centre split core castings for increased heat transfer and thermal efficiency
- CBN (Cubic Boron Nitride) machine turned finish, minimising disc thickness variation and the potential for pad “knock” and resulting premature wear
- Paint markings change colour at specific temperature thresholds to assist with the monitoring of braking temperatures and rotor fatigue
Disc Brakes Australia (DBA®) specializes in precision crafted brake rotors with innovative designs and material compounds that resist heat buildup far better than products from competitors - giving you increased stopping power with smooth progressive application, lower noise, vibration, and harshness, and greater resistance to the rotor warpage that shortens usable lifespan of all brake components. DBA offers a variety of slotted rotors with and without cross-drilled holes in traditional 1-piece construction and 2-piece aluminum center construction for reduced mass. Headquartered in Australia, DBA has United States operations in Detroit, Michigan. Our website is proud to offer the full lineup of DBA rotors at great values.
