My assumption is that they will need a totally new floor + diffuser to solve the issue so we might be in for a hell of a start unless the engineers figure out something ASAP
That's, in a nutshell, the essence of performance in this era. The better understanding and implementation of that, the better the performance.
Comes to the "classic" numbers in CFD & Tunnel vs the real world on track fluctuations in use.
It's easy when written, so hard to do though
If anything, the Chinese GP showed that
'it's not the car all the time, it's the driver as well'. LeClerc with missing downforce on the critical front left, had better tyre age on the M and H and was faster than Hamilton on both compounds. And didn't suffer plankwear. What does it say ?
1) LeClerc's 'lines' through T1-2-3 and T11-12-13 were far far better than Hamilton's (even in the sprint). I know it will hurt the fans of the 7 time WDC who is renowned as a tyre whisperer
('bono tyres are gone' and then doing the fastest lap on worn tyres) ; but on
this occasion, the evidence is there to see. At one point Hamilton was asking his race engineer - 'where am I losing time to Charles' , when he could clearly see in his mirrors and in front of him, how leClerc was driving the variable radius long corners completely different to himself.
2) LeClerc and Hamilton were most probably running two different ride height and spring stiffness setups. Otherwise, leClerc should have shown more plank wear considering his H had shed more tread and must have been riding lower.

This car is second fastest when they get the set up right and not far behind the McLaren, they can take that as a positive along with Lewis' masterclass in the Sprint Pole and Sprint Win but thats about it
again, not trying to piss on the 'masterclass' , but running super-low for added downforce resulting in a mega sector2 and mega traction from T12-13, helped him a lot.Plus the advantage of clean air. Just calling it as I see it. Goes to show the exact opposite of my reply above -
'it's not the driver all the time, it's the car as well'.

I feel, emphatically, that Ferrari are not doing anything wrong in how they arrange their sprint setup. Morally or "legally" howsoever it's considered.
To put it another way:- how many engineers in all the teams will miss setup optimisation for what, 50/60kgs less start fuel weight ? I bet not one of them.
That weight carried at start of full race though .... probably where most of the plank wear takes place .... in the first half of race laps.
Lewis may have been too candid in revealing the setup change and its effects after the shift between the two events. Others are noticeably quite on this topic.
Hamilton said they raised the height post sprint, and despite that the plank wore more than what they accounted for. That means they got their 'suspension stiffness v ride height v fuel load v plankwear' equations wrong. Perhaps they overdid the ride height increase in Australia, and underdid the same in China. I know it's super difficult, but they are a top top F1 team. Such optimizations should be 'low hanging fruit' for the kind of expertise they carry.

The excessive plank wear only occurred on one car. That doesn't suggest a fundamental issue to me.
Bingo, this talk of push rod v pull rod being the root cause is all incorrect, IMHO.
