DBA DBA542S Street Series T2 Slotted Disc Brake Rotor

The DBA DBA542S Street Series T2 is a direct OE-replacement slotted disc brake rotor built on over 40 years of DBA braking expertise. Engineered for daily drivers, light commercial vehicles, and SUVs, it delivers a meaningful performance upgrade over a standard OEM rotor without sacrificing street comfort or reliability.

Patented T2 Slot Design:

• CNC-machined bi-symmetrical slots reduce vibration harmonics and noise for a quieter, more responsive brake pedal feel
• Increased exit points allow friction dust and gases to escape, enhancing pad bite and braking responsiveness
• Even slot geometry promotes consistent pad wear and helps minimize pad surface glazing
• Universal bi-directional slot design eliminates the need for separate left and right rotor configurations

Kangaroo Paw Vane Technology:

• DBA's patented internal vane design features unique diamond and teardrop-shaped pillars for superior airflow
• Delivers up to 20% better heat dissipation compared to conventional rotor designs
• Increases dimensional stability under thermal load, prolonging rotor and pad service life

Premium Manufacturing & Finish:

• CBN (Cubic Boron Nitride) machine-turned friction surface minimizes disc thickness variation and reduces the potential for pad knock
• Surface machined to micron-level precision for a smooth bed-in and reduced premature pad wear
• Painted non-friction areas protect against rust and enhance appearance

The DBA DBA542S is the ideal choice for drivers seeking a proven, high-quality brake rotor upgrade that combines OEM fitment confidence with the added performance benefits of DBA's street-proven T2 slot technology.
