What I have noticed, though, is that when accelerating in a certain angle (mostly uphill) sometimes there is a weird vibration / noise from the bottom shield / skid. It goes away if you keep accelerating or decelerating. I think it has to do with the wind resonating with some parts. It is really weird.

I'm running 245/40 on 17x9 wheels. First time was at Daytona on the banking, the second time was at PittRace on the backside (slight curve), yesterday at Sebring on the back straight. Going to Road Atlanta in a couple of weeks, will remove the dif brace and see hat happens.
