Fresh details about Red Bull's new Miami Grand Prix upgrade have been released by the FIA, with Max Verstappen only to get the new parts.

Red Bull has brought a new floor to Miami as it tries to bridge the gap between it and McLaren, with a stream of developments coming to the RB21, with Miami delivering the latest batch. 

The team has brought new floor fences and a new floor edge to Florida, with the upgrades intending to re-optimise the floor edge fences to increase the load generated and maintain stability of the air-flow. 

The floor edge upgrade has new surfaces which increase the camber to help produce more local load.

Only Verstappen will use the upgrade, whilst team-mate Yuki Tsunoda continues with the old-specification of parts.

Elsewhere, Mercedes has brought a new rear-wing, with a circuit specific flap update to help in the reduction of drag along Miami's long straights. 

Alpine has also brought a big package, with revised front-brake ducts and front suspension being added to the A525, with Stake also bringing an updated front suspension cover design to aid improvement of air-flow structures along the car.

Meanwhile, Aston Martin has brought a front-wing, rear-wing and beam-wing design, but all these are circuit-specific to help reduce drag and boost aerodynamic efficiency and are not upgrades per se.
