DBA DBA4928XS 4000 Series XS Drilled and Slotted Performance Brake Rotor

The DBA DBA4928XS 4000 Series XS Gold brake rotor is a premium direct replacement performance brake disc designed for driving enthusiasts seeking upgraded braking performance beyond standard OE levels. This single-piece rotor combines advanced materials, innovative ventilation technology, and an aggressive cross-drilled and slotted design for exceptional stopping power and heat management.

Advanced Construction and Materials:

• Cast from XG150 high carbon alloyed iron for superior thermal capacity and durability
• Thermal Stability Profiling (TSP) process allows the rotor to handle extreme heat and stress during intense braking applications without warping or cracking
• CBN (Cubic Boron Nitride) machine turned finish minimizes disc thickness variation and parallelism, reducing brake shudder and pedal judder
• Attractive gold-colored finish on the rotor hub for enhanced aesthetics

Kangaroo Paw Ventilation Technology:

• Patented ventilation system featuring 144 diamond and teardrop-patterned pillars
• Achieves up to 30% increase in surface area compared to traditional straight vane designs
• Provides up to 20% improvement in cooling efficiency for better heat dissipation
• Minimizes brake fade and prolongs service life for both rotors and brake pads

XS Gold Cross-Drilled and Slotted Design:

• Premium non-directional cross-drilled and slotted pattern increases the number of exit points for brake pad friction dust and gases
• Symmetrical design allows for universal left/right installation
• Chamfered drill holes and slots facilitate evacuation of brake dust and gases for quieter, more responsive pedal feel
• Popular choice for show cars and open wheel applications where aesthetics matter
• Note: Drilled rotor configurations are not recommended for heavy track day usage

Additional Features:

• Paint protection on non-friction areas prevents corrosion and enhances appearance
• Heat-sensitive paint markings change color at specific temperature thresholds to help monitor braking temperatures and rotor fatigue
• Moisture-proof corrosion protection packaging

The DBA 4000 Series XS Gold rotor delivers performance benefits similar to the T3 slotted design while offering eye-catching aesthetics for enthusiasts who want both form and function. Sold individually.
