Please read. The device (if you even call it that since its quite rudimentary mechanical stuff) is not illegal at all. Every car can adjust its ride height. RB just has a different way of doing it. None of the other teams are questioning that and it's not the question. Its only the parke ferme question. And hey nothing wrong with questioning that. Like the mini drs, engine modes, DAS, double diffuser, all the tricks used on the braking and suspension systems etc etc etc either its a violation of some sort and rules are tightened regardless of whether there is a penalty, or the other teams are simply looking for the FIA to say it's ok to do as well.
