It looked like RBR were told by Pirelli that the tire is not safe to be run at the camber angle they were using it, only that this came after qualifying session and not before so if RBR made a setup change were doomed for the race.
In the end it came down to a FIA+Pirelli vs RBR fight and RBR won hands down.
Anyway I'm tired about the numerous tries to slow the RBRs this season. What next? RBR drivers only allowed to drive in reverse?
