DESCRIPTION:

Upgrade the rear braking system on your 2020+ Chevrolet Corvette C8 Z51 with the DBA Brakes DBA43929S T3 4000 Series Rear Brake Rotors. DBA's 4000 Series T3 is a direct-replacement, single-piece performance rotor designed for drivers seeking braking performance beyond standard OE levels. The DBA43929S combines high-carbon alloyed iron construction, Thermal Stability Profiling, DBA's patented T3 slot design, and Kangaroo Paw ventilation technology in a performance-oriented replacement rotor. DBA manufactures its 4000 Series rotors from high-carbon alloyed iron and subjects them to Thermal Stability Profiling. DBA states that these heat-treatment cycles realign the microstructure of the iron, increasing rotor stability and durability while allowing the rotor to withstand the increased stress and heat generated during intense braking applications. The T3 friction surface incorporates DBA's patented bi-directional slot design. Building upon the company's T2 slot, T3 adds precision CNC-machined tri-symmetrical slots that provide additional exit paths for brake-pad friction dust and gases. DBA states that this helps increase the consistency and effectiveness of braking while providing a quieter, smoother, and more responsive pedal feel. DBA recommends T3 rotors for high-performance applications. DBA's 4000 Series also features its Kangaroo Paw ventilation technology. This design uses 144 diamond- and teardrop-patterned pillars between the rotor faces rather than conventional straight vanes. DBA states that the design can provide up to 30% more internal surface area and approximately 20% improved cooling efficiency compared with a traditional straight-vane design. Additional 4000 Series technology includes center-split core castings for improved heat transfer, a Cubic Boron Nitride machine-turned finish designed to minimize disc-thickness variation, anti-rust protection on non-friction surfaces, and thermographic heat-paint markings that change color at specific temperature thresholds to help monitor brake temperatures and rotor fatigue. For the 2020+ Corvette C8 Z51 application specified for this listing, the DBA43929S provides a performance-focused rear rotor upgrade that retains direct-replacement, single-piece construction while adding DBA's T3 slotting, high-carbon metallurgy, thermal treatment, and advanced cooling technology.

Important Notes

  • The additional T3 slots increase the number of exit points available for brake-pad friction dust and gases.
  • The T3 configuration helps improve braking consistency and effectiveness while contributing to a quieter, smoother, and more responsive pedal feel.
  • The high-carbon alloy formulation increases the rotor's ability to handle constant and extreme heat over prolonged periods.
  • DBA's Kangaroo Paw ventilation system uses 144 diamond- and teardrop-patterned internal pillars.
  • DBA claims up to a 30% increase in internal surface area and approximately 20% improved cooling efficiency compared with a traditional straight-vane design.
  • Center-split core castings are used to increase heat transfer and thermal efficiency.
  • DBA uses a Cubic Boron Nitride machine-turned finish designed to minimize disc-thickness variation and the potential for pad knock and resulting premature wear.
  • Anti-rust paint is applied to non-friction areas to help prevent corrosion and maintain appearance.
  • Thermographic heat-paint markings change color at specific temperature thresholds to assist with monitoring brake temperatures and rotor fatigue.
