The mechanics work on the bib and plank of the Ferrari F1-75 as the changes are made between the two specifications.
Meanwhile, the team has a low downforce rear wing at their disposal which features a much flatter design than the usual configuration.
Red Bull has trimmed some of the front wing upper flap’s leading edge as it looks to balance the downforce level of the car, front-to-rear, to match the changes made on the rear wing.
The Aston Martin AMR22 fitted with a kiel probe rake between the front wheel assembly and sidepods as the team looks to gather data that will either corroborate the performance seen with simulation tools or help them with correlation.
Another shot of the AMR22 showing the team had fitted the kiel probe rakes to both sides of the car.
Meanwhile, Lance Stroll’s AMR22 was fitted with the extreme low downforce rear wing package that was briefly tested at Spa.
McLaren daubed its low downforce rear wing in green flow-viz paint during FP1 to get visual confirmation that the wing is performing as anticipated.
The sparks fly as the W13’s floor meets with the track surface as the car compresses. Also note the rear wing has an upper flap that’s been trimmed back on the trailing edge and then a Gurney flap has been applied to it.
It’s a similar story for Aston Martin as the forces are imparted on the AMR22 as it makes its way around the Temple of Speed. Flo-viz can also be seen on the rear wing, as it looks for confirmation that its aerodynamic design endeavors have worked.

More flow-viz paint, this time on the diffuser and new, single element beam wing, mounted on the Ferrari F1-75.
The rear wing fitted to Sergio Perez’s RB18 during Free Practice on Friday had a large cutout in the trailing edge of the upper flap as the team looked at options ahead of the competitive sessions.
AlphaTauri has employed a single-element beam wing in combination with the lower downforce rear wing.

Williams has painted flow-viz on its low downforce rear wing to establish if it’s performing as anticipated. You’ll note, as others have, the team has opted to trim the upper flap’s trailing edge and add a Gurney for balance.
Alfa Romeo are utilising a similar rear wing configuration as it did at Spa, with an abbreviated wingtip transition. However, what does differ is that the trailing edge of the upper flap has been trimmed.
