Product Details
If you're looking to replace the rear brake rotors on your 2007-2011 Mazda Mazdaspeed3, this 4000 Series HD rotor from DBA is a solid option. It's cast from XG-150 high carbon alloyed iron, which helps it handle the extra stress and heat that comes with harder braking. This material choice means the rotor can stand up to repeated use without warping as easily.
DBA has also incorporated their Kangaroo Paw ventilation system on these rotors. This design uses a series of diamond and teardrop-shaped pillars, increasing the surface area by up to 30% and improving cooling efficiency by 20% compared to standard straight vane rotors. This enhanced cooling is crucial for preventing brake fade during spirited driving or track use. The 'HD' in the 4000 Series HD means it has a smooth, OE-style finish, making it a popular choice for drivers who want the performance benefits of a 4000 Series rotor but prefer the look of a factory-style disc, especially for controlled race divisions.
