DBA DBA42121S 4000 Series T3 Slotted Brake Rotor

The DBA DBA42121S is a 4000 Series T3 Slotted brake disc engineered by Disc Brakes Australia (DBA) for drivers seeking improved braking performance over a standard OEM rotor. Designed for the rear axle of the Ford Focus XR5, this rotor is built to handle demanding street and performance driving conditions.

DBA's T3 Triple-Drilled Slotting Technology features a patented three-slot pattern that provides continuous and progressive rotor-to-pad sweep, effectively channeling gases, heat, and debris away from the braking surface. The result is reduced brake fade, improved bite, and more consistent stopping power under repeated hard braking.

Key Features:

• T3 Slotted Technology – Patented triple-slot pattern for superior heat dissipation and pad degassing
• 4000 Series Construction – Premium-grade iron alloy for durability and thermal stability
• Geomet® Coating – Corrosion-resistant finish on the hat and non-swept areas to prevent rust and extend rotor life
• Precision Machined – Tight tolerances for minimal runout and vibration-free braking
• Street & Performance Ready – Suitable for spirited street driving and light track use
• Direct OEM Replacement Fit – Bolt-on installation with no modifications required

DBA's 4000 Series T3 slotted rotors are a popular upgrade for performance-oriented vehicles, delivering the reliability and feel of an OEM rotor with the added benefits of enhanced thermal management and braking response. Sold individually.
