Product Description

The DBA DBA52771.1S is a high-performance rear brake rotor ring engineered for the 2015-2019 Chevrolet Corvette C7 (Grand Sport and Z06 without the Z07 brake package). Part of DBA's 5000 Series T3 lineup, this rotor ring features a bi-directional slotted surface that actively evacuates brake pad gases, dust, and debris, helping maintain consistent pad contact and improved braking response under demanding conditions. The slotted design also reduces pad glazing and contributes to a more predictable pedal feel during spirited driving or light track use.

Constructed from high-carbon alloyed iron and optimized with Kangaroo Paw ventilation and Thermal Stability Profiling (TSP), this rotor ring offers enhanced cooling and resistance to heat-induced distortion compared to conventional smooth rotor rings. Designed as a direct replacement for the rear rotor ring in compatible two-piece assemblies, this component pairs well with performance brake pads for enhanced everyday and performance braking. Fitment is confirmed for the listed Corvette C7 model years; coverage beyond these years is unconfirmed at the time of this listing.
