DBA DBA3421S Street Series Slotted Brake Rotor - T2 345mm

The DBA DBA3421S Street Series T2 Slotted Brake Rotor is a high-performance direct replacement brake disc designed for BMW applications requiring 345mm rear rotors. This rotor combines precision engineering with DBA's patented T2 slot technology to deliver enhanced braking performance for daily driving, towing, and spirited driving conditions.

Key Features:

• Patented T2 bi-symmetrical slot design for improved brake pad bite and gas evacuation
• CNC-machined precision slots reduce brake noise and provide smoother, more responsive pedal feel
• Universal slot pattern eliminates left/right directional requirements for easier installation
• Enhanced heat dissipation through advanced internal vane design reduces brake fade
• OEM-compatible dimensions for direct bolt-on replacement without modification
• Sold individually to allow flexible replacement options

The T2 slot design features precisely machined bi-symmetrical grooves that increase the number of exit points for friction dust and gases, maintaining consistent pad contact and braking performance. This advanced slot pattern helps prevent brake fade during sustained braking, making it ideal for drivers who frequently encounter demanding conditions such as mountain driving, towing, or performance applications. The DBA Street Series represents a significant upgrade over standard replacement rotors while maintaining full OEM compatibility.
