Ferrari insiders say the team is preparing a completely revised rear-suspension package for the SF-25, aiming to roll it out at the Belgian Grand Prix in Spa-Francorchamps later this month. The new design is expected to tackle the car’s chronic traction issues and widen its operating window, a weakness that has hampered Charles Leclerc and Lewis Hamilton throughout the 2025 season.
The project has been in the works since early May, but production delays and extended wind-tunnel validation have repeatedly pushed back its debut. According to Sky Sport Italia commentator Carlo Vanzini, the suspension was initially pencilled in for Silverstone; however, it now looks set to appear a race later so that the supporting floor upgrade can be manufactured in time and tested as a complete aero-mechanical package.
Ferrari’s engineering staff believe the new geometry—featuring a lower pull-rod pick-up and revised wishbone angles—should improve tyre longevity under heavy traction zones and give the rear diffuser a cleaner airflow. If the numbers from the Maranello simulator translate to the track, the team hopes to claw back significant downforce without compromising straight-line speed.
Team boss Frédéric Vasseur has tempered expectations, stressing that the Belgian introduction is “a step, not a silver bullet.” Still, the Scuderia sees Spa’s long straights and fast corners as an ideal proving ground before the high-downforce run-in at Zandvoort and Singapore. A successful debut could also reshape the development path for 2026, when sweeping aero regulations arrive.
For now, the story remains a well-sourced leak rather than an official announcement—Ferrari has yet to confirm the exact timetable in any press release. Nevertheless, multiple reputable Italian outlets, including Motorsport-Italia journalists, echo the Spa target date, lending strong credibility to the report. Fans will be watching the Belgian pit lane closely to see whether the SF-25 rolls out with its much-anticipated rea
r-end makeover.
