DBA DBA42315S Series Slotted Brake Rotor - 4000 T3

The DBA 4000 Series T3 slotted brake rotor is a high-performance, direct replacement disc rotor designed for drivers seeking upgraded braking performance beyond standard OE levels. Engineered for demanding applications including spirited street driving, track use, rally, 4x4/SUV, and towing, this rotor delivers exceptional heat management and consistent stopping power.

Advanced Materials and Manufacturing:

• XG-150 High Carbon Alloyed Iron - Superior metallurgy handles extreme stress and heat from intense braking applications repeatedly
• Thermal Stability Profiling (TSP) - Proprietary heat treatment process subjects iron to prolonged, controlled heat cycles to relieve internal manufacturing stresses, maximizing thermal stability and reducing metal fatigue
• Enhanced Durability - On average, these rotors last three times longer than most competitive rotors on the market

Patented Kangaroo Paw Ventilation:

• Features 144 diamond and teardrop-patterned pillars between rotor faces
• Delivers up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• Provides greater structural strength and faster heat dissipation

T3 Tri-Symmetrical Slot Design:

• Precise CNC-machined tri-symmetrical slots for quieter, more responsive and smoother brake pedal feel
• Increases exit points for brake pad friction dust and gases to escape, improving consistency and effectiveness
• Universal bi-directional slot design eliminates the need for separate left and right rotors
• Provides aggressive pad bite while managing heat buildup effectively

Thermo-Graphic Heat Paint Markings:

• Green line changes to white at 856°F
• Orange line changes to yellow at 1,022°F
• Pink line changes to white at 1,166°F
• Allows drivers to monitor rotor temperature and optimize brake system performance

Additional Features:

• Black anti-rust coating on non-friction areas for corrosion protection
• One-piece rotor construction for direct replacement installation
• Sold individually - two required per axle
• Backed by manufacturer warranty for 12 months or 12,000 miles

The DBA 4000 Series T3 rotor combines advanced metallurgy, innovative ventilation technology, and precision slotting to deliver superior braking performance, reduced fade, improved pedal feel, and exceptional longevity for performance-oriented drivers.
