Floor Winglet
Chapter: C3
In Simple Terms
Teams can add small winglets to the floor of their car that stick out from the sides. These winglets can be slightly angled (up to 5 degrees) and moved a tiny bit side-to-side (up to 10mm) to help fine-tune how air flows around the car. They're a special exception to the normal floor rules and can have up to two different sections stacked vertically.
- Floor winglets are small aerodynamic devices exempt from standard floor regulations
- They can be rotated ±5 degrees around a vertical axis and moved ±10mm in height for adjustment
- Maximum of two sections allowed in any vertical plane
- Must comply with the RS-FLOOR-WINGLET specification and use a single hanger attachment
