DBA DBA3431S Street Series T2 Slotted Disc Brake Rotor Rear

The DBA DBA3431S is a Street Series T2 Slotted disc brake rotor from Disc Brakes Australia (DBA), engineered to deliver enhanced braking performance over standard OEM rotors. Designed for rear axle fitment on compatible BMW Z4 E89 models, this rotor combines DBA's proven slotting technology with quality metallurgy suited for everyday street driving and spirited use.

T2 Slot Technology:

• T2 Slotted Design – DBA's T2 slot pattern evacuates heat, gas, and brake dust from the rotor surface, improving pad bite and reducing brake fade
• Street-Optimized Performance – Balanced for daily driving comfort while offering a meaningful upgrade over standard OEM rotors
• Premium Metallurgy – Manufactured from high-quality grey iron for consistent thermal stability and long service life
• Corrosion Resistance – Zinc-washed finish on non-braking surfaces helps resist rust and corrosion during storage and service
• Slot Pattern – Continuously sweeps the pad surface to maintain a clean, even pad face and minimize glazing
• Direct OEM Replacement – Designed as a bolt-on fitment, requiring no modifications for installation

The DBA3431S is part of DBA's popular Street Series lineup, offering drivers a straightforward performance upgrade with minimal compromise on noise or ride comfort. Ideal for enthusiasts looking to improve braking feel and consistency on their BMW Z4 E89.
