The 991 GT3 RS features dedicated functional aerodynamics, including a prominent fixed rear wing, front fender louvres for pressure extraction, and NACA ducts on the 991.2 bonnet. To further tune high-speed downforce and aerodynamic balance, front-end lift can be reduced by fitting Front Splitters, Front Canards, and protective Front Grilles. Directing airflow to the front callipers is achieved using Misc Brake Parts (Air Feeds), whilst Upgraded Undertrays smooth underbody air velocity. To refine the side profile and manage lateral turbulence, Side Skirts can be added. Rear aerodynamic grip and stability can be enhanced using Rear Diffusers, Rear Spoilers, Rear Valances, Rear Splitters, Rear Side Splitters, and Spoiler Caps. We also stock Misc Exterior Parts for precise bodywork adjustments.
