Hi Adam, I am pretty confident that fixed means fixed in relation to the body, not just that it can't fall off.....these rules have been in place a long time and active aero is not a new idea
good to hear, I would hate to see it impact the champioship
You might be surprised about how little quicker other cars can go through there, it very quickly becomes a question of outright grip and the weight of the car. Anything over 1200kg is likely to have comparable speeds through there, and that includes up to supercars (I do not know their exact speeds, but not much over 200, ie within 10% of your speed). Of course a sports sedan with full aero and 800kg carries a few km more and I guess the formula cars are running up to 240 though there.
I doubt it has much if anything to do with your commitment in the turn. Very strong top speed btw considering how stock it is.
