DBA DBA42029 4000 Series Plain Faced Uni-Directional Brake Rotor

The DBA DBA42029 is a 4000 Series plain-faced, uni-directional brake rotor engineered for drivers who demand consistent, high-performance stopping power under demanding conditions. Built with High Carbon Alloyed Iron (XG-150), this rotor delivers superior strength, reduced noise, and extended service life compared to standard cast iron rotors.

DBA's proprietary Thermal Stability Profiling (TSP) technology is machined into the rotor to manage heat distribution across the braking surface. This allows the rotor to withstand repeated extreme heat cycles — making it an ideal choice for spirited street driving, track days, and those critical late-braking scenarios where consistent fade-free performance is essential.

Key Features:

• XG-150 High Carbon Alloyed Iron construction for improved strength, reduced vibration, and longer rotor life
• Thermal Stability Profiling (TSP) for optimized heat distribution and resistance to thermal fatigue
• Plain-faced, uni-directional rotor design for broad compatibility and straightforward installation
• Engineered for repeated extreme heat cycles and high-performance braking demands
• Part of DBA's 4000 Series lineup, positioned for performance street and light track use

The DBA 4000 Series represents a significant upgrade over OEM rotors for drivers seeking better thermal management and rotor longevity without the complexity of slotted or drilled designs. Manufacturer Part Number: DBA42029.
