That’s interesting as SkyF1 are reporting RB (not confirmed) have asked the FIA to bring forward a technical directive change. Apparently the FIA expect for this weekend, and the next two races, teams to alter their skid blocks, not the skid plank. The blocks are titanium, they create the sparks, and protect the plank from excessive wear. Two days to get the parts manufactured and on the cars before the race (possibly qually) is very harsh.
Being cynical this would also affect RB, but if they pushed for the change then it would be reasonable to assume they had the parts ready to go,
