Upgrade the front brakes on your 2020+ Chevrolet C8 Corvette Z51 with the DBA Brakes DBA43928S T3 4000 Series Front Brake Rotor. Designed specifically for C8 Corvettes equipped with the Z51 Performance Package and J55 brake system, the DBA43928S is a direct-replacement, single-piece performance rotor engineered for drivers demanding braking performance beyond standard OE levels. At the heart of the DBA 4000 Series is a high-carbon alloyed iron construction developed for increased thermal capacity under demanding braking conditions. DBA subjects its 4000 Series metallurgy to Thermal Stability Profiling, helping the rotor withstand the elevated temperatures and stresses associated with repeated aggressive braking. The DBA43928S adds DBA's patented T3 bi-directional slot design to the performance foundation of the 4000 Series. Building upon DBA's T2 design, the T3 configuration incorporates additional precision CNC-machined tri-symmetrical slots. These slots increase the number of pathways through which brake-pad friction dust and gases can escape, helping promote consistent and effective braking during repeated stops. DBA also states that the T3 configuration provides a quieter, smoother and more responsive brake-pedal feel. Another important component of DBA's 4000 Series technology is its Kangaroo Paw ventilation system. Rather than conventional straight cooling vanes, Kangaroo Paw ventilation incorporates 144 diamond- and teardrop-shaped pillars between the rotor faces. According to DBA, this arrangement provides up to a 30% increase in surface area and up to a 20% improvement in cooling efficiency compared with a traditional straight-vane design. DBA recommends its T3 slot design for high-performance applications, making the DBA43928S an excellent option for Z51 owners looking for a performance-oriented replacement rotor for spirited street driving, autocross, HPDE, or track use. For C8 Corvette Z51 owners who want to retain the factory-style single-piece front rotor configuration while gaining DBA's high-carbon metallurgy, Thermal Stability Profiling, advanced ventilation and T3 slotted friction surface, the DBA43928S provides a direct-fit performance upgrade engineered specifically around the Z51's 345mm front braking system.

Important Notes

• Verify that the vehicle is equipped with the Z51/J55 front brake package before ordering.
• DBA43928S is a single-piece direct-replacement performance rotor. It is not a two-piece rotor or replacement friction ring.
• The 4000 Series uses high-carbon alloyed iron and DBA's Thermal Stability Profiling to withstand increased thermal stress during demanding braking.
• For aggressive street or track use, select brake pads with an operating-temperature range appropriate for the intended application.
• Proper bedding helps establish a consistent friction-material transfer layer on the new rotor surface.
• High-temperature brake fluid appropriate for the vehicle and intended driving environment should be considered for track applications.
