Function over form, once again. That wing was put on there by one of the engineers who worked at Dallara on the Audi R8 project. Seeing the R8's track record, I do believe these guys know what they are doing. And in fact, just last weekend, the tC in that picture, still fwd, finished 5th overall at the big Time Attack event. Top 8 results:
FX Motorsports/Cricket NSX, 1:18.555
Sierra Sierra EVO 8, 1:20.454
C-West S2000, 1:20.838
Crawford STI, 1:22.097
World Racing Scion Tc, 1:22.623
GST Impreza, 1:23.141
Evasive Motorsports EVO 8, 1:23.300
Fontana Nissan 350Z, 1:23.846
Faster than a bunch of 500whp+ 4wd track machines? Looks stupid, but works really well.
