Vented, drilled and slotted right rear cast iron brake rotor for Chevrolet Corvette C2/C3 1965–82. Delivers consistent, predictable brake pedal response, effective self-cleaning of the pads and a corrosion-resistant surface, ideal for demanding, performance-focused street and track use.
OE-style replacement rear axle rotor for Corvette C2/C3 that combines Wilwood's SRP pattern (drilled & slotted) with a vented 32 mm rotor for stable thermal control and enhanced braking performance. The black electrocoat protects non-swept areas against corrosion, while the precision-machined friction surface ensures consistent pad contact and smooth, predictable braking over time. A proven brake upgrade for pro-touring and restomod applications, as well as Corvette C2/C3 vehicles subjected to intensive use on the street, in autocross and at club-level track events.
- SRP drilled and slotted friction surface that resists glazing, improves cooling and promotes even pad material transfer for consistent braking performance.
- Vented 32 mm construction for efficient heat dissipation and reduced brake fade under repeated heavy braking.
- Black electrocoat on exposed areas for durable corrosion protection in both everyday and performance driving.
- Precision-machined rotor with tight tolerances for flatness and parallelism, reducing the risk of vibration and brake pulsation.
- OE-style right-side (R/H) rear replacement rotor engineered specifically for Chevrolet Corvette C2/C3 1965–82.
- Bolt pattern 5 x 4.75" – standard GM bolt circle; verify hub and stud dimensions during installation to ensure correct fitment.
- Developed for spirited street driving, autocross and club-level track use; a trusted option for upgraded C2/C3 Corvette builds focused on improved braking performance and control.

Installation and usage guidelines
- Observe the specified direction of rotation and mounting side: this is the right-hand rotor. Confirm the orientation of the drill/slot pattern during installation to ensure correct function and optimal pad cleaning.
- Thoroughly clean the hub and mating surfaces and measure rotor runout; shim or correct as required to minimize vibration, noise and uneven braking.
- Follow the recommended bedding-in procedure for new rotors and pads to establish even pad transfer, stable friction characteristics and maximum braking performance.
- Select brake pads according to the intended application (street, autocross, track). For sustained, intensive track use, a slotted, non-drilled rotor is often preferred for improved crack resistance.
- Check wheel stud dimensions and confirm that the lug nuts pass freely through the rotor before final assembly to ensure a safe, secure installation.
For Corvette C2/C3 brake upgrade projects where the classic GM 5 x 4.75" bolt pattern is to be combined with a more modern pedal feel, enhanced brake control and a durable, corrosion-resistant finish, this Wilwood rear brake rotor offers a well-balanced technical solution. Suitable for vehicles driven actively on the road and at club level, where stable, predictable brake response, reliable heat management and long-term durability are key priorities in a car that is both regularly used and continuously developed.
