Ferrari has unveiled the big upgrade package for the Bahrain Grand Prix that Lewis Hamilton hopes can turn his fortunes around.
Despite winning the Shanghai Sprint, Hamilton has largely struggled to find a balance he is happy with aboard the Ferrari, and claimed after the Japanese GP that a component on his car was not working correctly.
The seven-time champion added that new parts would be delivered for the Sakhir weekend, which he hopes will cure his struggles with rear-end instability in particular.
As such, Ferrari have delivered five big upgrades to the floor, diffuser and rear-wing of the SF-25.
New floor fences, floor body, and floor edges have been delivered, targetting "an improvement of the losses travelling downstream" according to Ferrari's official submission documents.
The idea is to channel more air from the floor to the diffuser to create more rear-downforce, and combat Hamilton's troubles with the rear instability.
The diffuser has also been redesigned to aid in this, whilst the rear-wing tweak is a new pillar winglet to improve aerodynamic efficiency.

McLaren and Red Bull bring updates
Elsewhere, McLaren has deployed a new front-wing brake duct winglet to better control the airflow and aerodynamics of its MCL39.
Title rivals Red Bull have also brought fresh upgrades for Max Verstappen and Yuki Tsunoda, with a new longer chord flap to the front-wing to potentially increase the load generated and work better with the rear-wings available to the team.
Red Bull and Haas have also brought circuit specific cooling parts, with both set to run the wider cooling louvres on their engine covers to feed more air into the engine, thus cooling it.
