Vehicle Fitment

• 2020-2027 Chevrolet Corvette Stingray (C8) with Z51 Performance Package -- 6.2L V8
• Coupe and Convertible models with Z51 Brembo rear brake calipers

Fitment Notes

• Rear axle only -- sold as a pair (left and right)
• Requires Z51 Performance Package with Brembo rear calipers and 350mm rotors
• EBC recommends using EBC brand brake pads to avoid rotor damage
• Matching front rotors available separately (EBC SG2F027)

Features

• Fully floating 2-piece design -- outer ring expands up to 3mm freely under heat
• Eliminates thermal warping during hard braking
• G3500 high-carbon, high-copper cast iron friction ring
• Superior crack resistance and thermal conductivity vs. OE
• Aerospace-grade aluminum bell, precision machined and hard anodized
• Patented SD-Drive stainless steel bobbins -- corrosion-resistant floating mechanism
• 48 directionally curved vanes (handed L/R) for maximum cooling
• Slotted surface vents pad gases and clears dust, water, and debris
• Anti-rattle spring clips at each bobbin -- silent on-street operation
• Significant unsprung weight reduction vs. OE 1-piece rotors
• Replaceable outer ring -- bells and bobbins reusable for lower long-term cost
• Thermic black corrosion-resistant finish

Product Description

The EBC SG2F028 is a pair of 2-piece fully floating rear brake rotors engineered for the 2020-2025 C8 Chevrolet Corvette Stingray equipped with the Z51 Performance Package and Brembo rear calipers. Measuring 350mm x 27mm, these rotors bolt directly onto the rear axle as a direct replacement with no modifications required. The outer friction rings are cast from high-carbon, high-copper G3500 alloy for exceptional crack resistance and thermal conductivity, while the center bells are precision machined from aerospace-grade aluminum and hard anodized for long-term durability. EBC's patented SD-Drive stainless steel bobbins allow the outer ring to float freely and expand up to 3mm under extreme heat, virtually eliminating thermal distortion during hard driving. Each rotor features 48 directionally curved vanes in a handed left/right configuration for maximum cooling, and a slotted surface that promotes pad degassing while clearing debris. Anti-rattle spring clips at each bobbin ensure silent street operation. The 2-piece design significantly reduces unsprung rotational mass compared to OE 1-piece rotors, improving handling, turn-in response, and road holding. When the friction ring wears, only the outer ring needs replacement -- the bells and bobbins are fully reusable. Pair with the EBC SG2F027 front rotors for a complete C8 Z51 floating rotor upgrade.
