Sounds like the typical “peaky” floor design again requiring a suspension with compromised compliance to keep it working and still they have porpoising. In Italian, but basically the the car suffers from a weak front end and to gain some DF the car needed to be lowered. This triggered porpoising at an earlier than expected speed, the the suspension was stiffened and with that all the issues of drivability (oversteer) and poor tire life:
Hard to understand why they were not able to hit the ground running with a proper single-pillar RW when all they did was a warm over of last year’s car with the steering rack lowered (to where it should have been last year) and the lower SIS left as is—resulting in the silly little bumps and no development leeway for more undercut—while other teams basically revolutionized their cars.
