Mercedes has also opted to bring a solitary upgrade to Suzuka, electing to modify the Rear Wing via the addition of a vane on the outer face of the endplate, designed to generate additional downforce.
McLaren’s mighty development process continues with two further revisions to the MCL60: a new offloaded beam wing and a sidepod inlet packer. The former is designed specifically to meet the aero requirements of Suzuka and the latter to improve airflow and cooling.
Aston Martin will be looking to bounce back from the team’s first pointless weekend of 2023 in Singapore and aims to get back in the scoresheet via a solitary circuit-specific upgrade.
The AMR23 sees revisions made to the front brake ducts, with a smaller inlet area typically incorporated for circuits such as Suzuka where braking requirements are lower than average.
AlphaTauri has made two upgrades to the AT04 for this weekend’s action.
The first is a modification to the rear wing tips, said to work in harmony with Suzuka’s specific aero requirements, while the second is the reintroduction of a part tested at Monza – namely the rearview mirror minus three turning vanes.
AlphaTauri seeks to discover how the removal of the turning vanes affects the AT04 at Suzuka, in comparison to the low-drag Monza circuit.
Williams is the final team to bring any sort of upgrades along for the Japanese GP, having reduced the height of the most inboard forward floor fence on the Gulf-liveried FW45.

Along with Red Bull, Alpine, Alfa Romeo and Haas didn’t bring any upgrades to Suzuka this weekend, with the latter putting a pause on its current car concept, in order to debut a revised ‘downwash’ concept in Austin next month.
