The thing is that when you look at the accident, they were reporting about grounding, which caused the accident. Prior losing control you could see sparks flying underneath the car, meaning the floor was rubbing the asphalt. On Sunday however, Lewis was literally flying throughout the race and imho I didn't notice sparks underneath the car at that very specific turn.
So was it because Lewis running a higher rake setting? I don't think so, because if so, we would have noticed it on FP1,2 and 3.
I'm still wondering if Merc still has a legal version of the trick suspension.
