Audi TT Quattro Brake Rotor (1) - Rear - DBA - 4000 Series HD Plain - '09-'15. This rear plain rotor from Disc Brakes Australia (DBA) is a direct-fit replacement for Audi TT Quattro models 2009–2015, built to deliver consistent, repeatable braking under demanding use.

Casted from XG-150 high carbon alloyed iron and processed with DBA’s Thermal Stability Profiling (TSP), the 4000 Series HD rotor balances durability with predictable wear. It features DBA’s patented Kangaroo Paw ventilation—144 diamond and teardrop patterned pillars—that increases surface area and improves cooling versus traditional straight vane designs. The HD variant provides a smooth OE-style finish favored by enthusiasts who want race-capable thermal control without a drilled or cross-drilled appearance. Rotors include THGP thermo-graphic paint markings and moisture-proof corrosion protection packaging for storage and transport, and are engineered as a direct replacement for the specified TT Quattro rear application.
