Product Description

The BC Racing Q-15-BR kit converts the C5 and C6 Corvette from its factory transverse composite leaf springs and separate dampers to a true coilover suspension at all four corners. The conversion provides direct control over ride height, spring rate and damping without relying on the factory leaf springs.

Each monotube damper provides 30 adjustment levels that change compression and rebound together. This allows the suspension to be softened for street use or firmed up for more responsive handling during autocross, track days or spirited driving.

Ride height is adjusted through the coilover assembly independently of spring preload. The standard kit uses 10K front and 12K rear springs and ships in BC Racing's Extreme Low configuration for the Corvette chassis.

Standard Springs vs. Swift Springs

• BC Racing Springs: Standard 10K front and 12K rear springs included with the base kit
• Swift Springs: Lighter springs with increased stroke and more consistent spring-rate characteristics

Swift Spring upgrades and custom spring rates are considered custom configurations. Additional service fees and manufacturing lead time may apply.

Before You Buy

• Confirm that the Corvette still uses compatible stock lower control arms
• Cars equipped with Magnetic Ride Control require additional electronic modifications
• This kit ships in the Extreme Low configuration and is intended to lower the vehicle
• Custom spring rates and Swift Spring upgrades may require an additional $150 custom-build fee
• Custom-built coilovers generally cannot be canceled or returned after production begins
• Professional installation is strongly recommended because the factory leaf springs must be removed
• A complete four-wheel alignment is required after installation
• Corner balancing is recommended for track-focused setups

Pairs Well With

• Progress Front and Rear Sway Bar Kit for C5 and C6 Corvette - Adds a 35mm tubular front bar and adjustable 25mm tubular rear bar for additional roll control.
