Ridgeline Motorsports Pre-Preg Dry Carbon Clubsport Dive Plane & Lower Side Spoiler Pack for Porsche 718 GT4/GT4 RS

Engineered for Maximum Performance. Inspired by Porsche Motorsport. Developed for Front-End Stability.

The Ridgeline Motorsport Canard Kit is a lightweight, motorsport-focused aerodynamic upgrade developed for the Porsche 718 Cayman GT4 RS and compatible GT4 front-end configurations.

Constructed from pre-preg dry carbon fiber, the canards are designed to generate controlled aerodynamic vortices that organize airflow around the sides of the front bumper and front wheels. This helps manage front-wheel wake, reduce disruptive airflow around the wheel openings, and support increased front-axle downforce at higher speeds.

When combined with the extended lower side spoilers and supporting GT4 RS front aerodynamic components, reference aerodynamic data for this configuration indicates an increase of up to 17% in front-axle downforce at 125 mph.

The result is a functional front aerodynamic upgrade designed to improve high-speed stability, front-end confidence, and overall aerodynamic balance while complementing the factory Porsche body lines.

Vehicle Fitment

Designed for:

• Porsche 718 Cayman GT4 RS
• Porsche 718 Cayman GT4 equipped with the GT4 RS Lip Set

Fitment and required mounting components vary depending on the vehicle configuration. Porsche 718 Cayman GT4 models must be equipped with the required GT4 RS-style front lip components before installation.

Please confirm compatibility and the required mounting configuration before placing your order.

Aerodynamic Function

The Ridgeline Motorsport Canards generate controlled vortices along the sides of the vehicle, helping guide airflow around the front wheels and manage turbulence created by the rotating tires and wheel openings.

Working together with the extended lower side spoilers and supporting front aero components, the canards help maintain more organized airflow through this critical area while increasing aerodynamic loading over the front axle.

Reference aerodynamic data for this canard and lower-side-spoiler configuration indicates up to 17% additional front-axle downforce at 125 mph. Actual performance may vary depending on ride height, vehicle setup, installed aerodynamic components, and surrounding airflow conditions.

Canards

The Ridgeline Motorsport Canards combine a motorsport-inspired dive-plane profile with lightweight pre-preg dry carbon fiber construction.

Their extended aerodynamic surfaces are designed to improve airflow control around both sides of the front wheels while adding functional front-axle loading at speed. The shape follows the factory GT4 RS front bumper geometry, providing an integrated appearance without compromising its motorsport-focused purpose.

Depending on the installation method and vehicle configuration, the canards can be installed with minimal modification to the painted front bumper.
