The FIA is planning to implement regulatory changes for the 2027 Formula 1 season to close a technical loophole utilized by Red Bull Racing. The innovation involves a floor body stay—a cable running along the ridge of the sidepod—which allows the team to maintain sharper aerodynamic edges by utilizing a 20mm radius near the support.

To eliminate this advantage, the FIA intends to restrict the permitted dimensions for these floor supports, potentially reducing the allowed radius from 20mm to 5mm. This change will require Red Bull to redesign that section of the car to comply with the updated regulations.
