FIA bans movable wings in the rain
The decision to prohibit use of the device during rain-hit races was made prior to the start of the season, but Whiting has opted to make further changes to the regulations amid safety concerns at a meeting with key F1 personnel on Thursday.
"As discussed in the team managers meeting yesterday, I would like to confirm that for safety reasons the driver adjustable bodywork permitted by Article 3.18 of the Technical Regulations may not be operated in any practice session (qualifying included) if the car is fitted with intermediate or wet-weather tires," Whiting stated.
"Any driver using the adjustable bodywork whilst the car is fitted with intermediate or wet-weather tires will be reported to the stewards as being in breach of Article 2.3 of the Technical Regulations."
