Front lower downforce undertray carbon fibre. Porsche 718 Cayman GT4 RS ❭ 99150460109

First-Time Abundance of Front Downforce for the GT4 RS
The Porsche GT4 model has long been criticized by track enthusiasts for lacking front downforce. However, the SR AeroShield has changed this situation. The Aeroshield provides the GT4 RS with unprecedented front and mid-front downforce. Players can freely adjust the front downforce of the GT4RS by changing canards to suit different types of tracks.
Drag-Free Downforce
Not all downforce is created equal. The underbody downforce generated from Venturi effects, boasts the highest downforce-to-drag ratio, ensuring superior performance without compromising speed.
More Balanced Downforce
The SR AeroShield enhances underbody airflow, generating an impressive 65 kg of additional downforce at 200 km/h. Most importantly, this downforce is evenly distributed along the underbody, resulting in a more balanced and stable driving experience at high speeds. To ensure SR customers achieve the most optimal results from our Aero Pack, we conducted intensive track testing with professional drivers to identify the ideal aerodynamic balance setup. Below is the recommended Aero Balance Table, summarized from all track testing data.
Stealth Performance in 20 minutes
The SR Front Aeroshield is designed to be virtually invisible, allowing for quick installation or removal in just 20 minutes—dominating the track like a wolf in sheep's clothing.
No impact on daily usage
The AeroShield is engineered to maintain the OEM minimum clearance, ensuring that your GT4 RS remains fully functional for everyday driving.
A cutting edge shield protecting your Porsche OEM underbody
Constructed from high-strength, aerospace-grade dry carbon fiber, the SR Aeroshield boasts a strength that is 4.3 times greater than that of aluminum. It provides exceptional protection for the front OEM underbody aluminum tub.
Important Notice
The SR Front AeroShield is meticulously designed to optimize downforce when paired with the SR DRS-1/Clubsport Wing (9GT825871A/2KIT) at high speeds. Through extensive CFD simulations and track testing, we have gathered the necessary setup data to ensure an ideal aerodynamic balance. Detailed AeroBalance setup Table is provided in the pictures section.
To maintain driving safety and aerodynamic stability at high speeds, SR intends to sell the AeroShield exclusively with the DRS-1/Clubsport Wing, or to existing customers who have already purchased the DRS-1/Clubsport wing. However, we have received numerous inquiries from customers who already bought wings from other brands.
The SR AeroShield has only been tested and aerodynamically matched with the DRS-1/Clubsport Wing so if used with any other rear wing, this is done at the owners risk
