Article C3.11.2
Rear Wing Endplate Body
Chapter: C3
In Simple Terms
The rear wing endplate (the vertical part at the edge of the wing) must fit entirely within a specific boundary box defined by regulations. It can have up to two distinct sections when sliced horizontally, and from the side view, it must completely hide the rear wing support structure behind it.
- Endplate bodywork must stay completely within the RV-RWEP-BODY boundary zone
- Maximum of two sections allowed in any horizontal cross-section (Y-Plane)
- Endplate must fully obscure the rear wing support (RS-RWEP) when viewed from the side
- These restrictions prevent teams from creating oversized or irregularly shaped endplates for aerodynamic advantage
