It appeared that Marko's scrape had done more harm to his rival, Luca, than just cracking a visor.
Both airborne debris and track-running debris were never good. Downforce was essential in Monza, so anything that could compromise it was danger.
Just one lap after the cracked visor was diagnosed, Trampos' radio also confirmed that Luca's diffuser had a problem.
The diffuser was located between the rear wheels and directly under the rear wing. Its primary job was downforce, as it contributed 25–40% of it.
A piece of Marko's debris had wedged itself there in the fins, and Luca's car had begun losing rear stability the longer it remained there.
Team and driver alone were aware of the situation as Luca did his best to mask any hint of instability in his driving.
No rival should sense the imbalance of his Ferrari.
He was more prone to sliding now, and to faster overheating of tires than they already were.
