No disrespect intended mate
I just don't see how putting a cap on the FFB would do anything to improve or make the competition better really. In the end it would only make things more unfair, as everyone has there preferences for FFB levels for whatever reason, that they've grown accustomed to over time. Not to mention that that each driver is FREE to choose whatever FFB level suits them best...which in the end is fair for every driver. I just think that by fixing the FFB levels you're only going to cater to whatever group of drivers that regularly drives at that FFB level, and possibly push others out of their comfort zone...which is far from necessary IMO.
And as I mentioned, all the wheels have dramatically different levels of FFB and quality of FFB to begin with, so making the FFB equal across the board is still nearly impossible to judge.
That's just my 2 cents though
