Experience cannot be replaced by bluster and assumption; if you read batman's post, it actually says nothing, except for provide an ego boost for the writer and insult large sections of the community.
My car was used to re-pattern the APR mounting bracket, since the jig had been lost several years ago. I went to APR's factory several times with my car in order for them to be able to once again sell wings to NSX owners, and was able to see the CFD results first hand for their wing. At the time, the modelling was very low resolution, and their wings were simply scaled up or scaled down for different cars. They had one aerofoil, for S2000, Corvette, NSX, Supra, Evo, etc.
On one hand it was nice to see them apply physics to their design, some companies like Taitec didn't bother, on the other, it's the most basic of work for this type of part. Also, CFD is not a replacement for wind-tunnel testing on a vehicle, just ask Virgin F1.
It's perhaps telling that a premium product is taking market share away from a less expensive option - certainly this is the result of function, and not simply vanity.
As batman suggests, there's a demographic shift in the NSX community; many people like to sway towards less-expensive items with cursory arguments, however, the Voltex is a superior product, if you're willing to pay for it.
