Haas team principal Guenther Steiner says there is no longer a grey area in the regulations around the use of pre-loaded suspension systems after the FIA issued a technical directive this week.
Trick suspension systems pioneered by Mercedes and Red Bull last year have been in the spotlight after Ferrari sent a letter to the sport's governing body over the winter questioning whether such a device would be legal on this year's car. Ferrari's letter referenced Article 3.15 of the regulations, which states "any specific part of the car influencing its aerodynamic performance must remain immobile in relation to the sprung part of the car" and questioned the legality of suspension parts that are specifically designed to aid the aerodynamics of the car.
