Well yes, ok, technically you’re right but this is definitely one of those Internet sayings that is mostly bull****. Sure it requires some work to get right but everyone running in non-restricted class has made aerodynamic improvements without wind tunnels or CFD models with fantastic results. You just have to follow proven aerodynamic approaches. My wing knocked almost 3 seconds off my VIR lap time day one (after spending a year looking for tenths of seconds else where). Sure tunning, testing and suspension adjustments were required after the fact to dial the wing in but this stuff isn’t as hard as the internet would lead you to believe. In fact I think aero is easier and lower risk than suspension modifications.
As far as butt dyno’s go track guys have a lot of tools at their disposal now. Not only do we have lap times, segment times, etc but we also have GPS data, lateral acceleration,, braking performance etc that can be over-layed with pre-modification laps. I can tell you how this modification is performing on every inch of the track. Really cool stuff.
