Overview

The SilverRocket Ultra Downforce Front Aeroshield is a dry carbon fiber underbody aero element developed exclusively for the Porsche 718 Cayman GT4 RS. Constructed from aerospace-grade dry carbon fiber with structural strength rated 4.3 times that of aluminum, the Aeroshield mounts beneath the front fascia to channel airflow under the chassis and generate Venturi-effect downforce — addressing the front-end aero deficit long noted on the track-driven 718 GT4 platform.

SilverRocket's CFD modeling and on-track validation recorded 65 kg of additional downforce at 200 km/h, distributed evenly along the underbody for balanced front-to-rear loading at speed. The Aeroshield generates this downforce primarily through Venturi-driven underbody airflow, which carries the highest downforce-to-drag ratio of any bolt-on aero solution — meaning the gains arrive without a corresponding top-speed penalty. The component preserves OEM minimum ground clearance, so daily driving and ramp transitions remain unaffected.

The Aeroshield is engineered as the front complement to the SilverRocket DRS-1 Flex-Carbon Swan Neck Wing or the SR Clubsport Wing — SilverRocket publishes an Aero Balance Setup Table calibrated against both pairings to help operators dial in the correct angle of attack across track configurations. For owners running the factory rear wing, SilverRocket's track testing confirms a balanced setup is achievable when the OEM wing is paired with the SR 3X3 Pro Wing Riser and Mini Gurney Flap. Installation and removal each take approximately 20 minutes, supporting trailer-to-paddock track-day workflows. Direct fitment is the Porsche 718 GT4 RS only.
