Because it's not the wind they are battling, it's just air resistance they are really battling. Aero is a huge advantage, the S1 Exige's rear wing at 100mph put the equivelent of 3 bags of cement on the rear, if you get rid of that down the stright, your going to be faster. F1 wings are alot more technical too, so god knows how much they push down at 200mph :\
