4000 Series XS Gold Rear Brake Rotor

The DBA 4000 Series XS Gold Brake Rotor is a rear performance upgrade for drivers seeking enhanced stopping power beyond standard OE specifications. They feature DBA's 4000 Series XS Gold rotor design, which includes a unique non-directional cross-drilled and slotted pattern that contributes to increased passive cooling. Typically incorporating DBA's patented Kangaroo Paw ventilation, which uses a series of 144 diamond and teardrop patterned pillars, these rotors achieve up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs. This advanced ventilation system helps dissipate heat more effectively, reducing the risk of brake fade and prolonging rotor life. This specific rotor (DBA42633XS) has a 350mm outside diameter, 28mm nominal and discard thickness, 64mm overall height, and a 72mm center hole diameter with 5 lug holes.
