if i can make it happen i'll cover the exhaust and ds under the car to have under the car as flat as possible. the rear engine cars are so easy to make the under flat. my friend's mr2 is also all flat till the rear where the engine is. i also noticed prius have something like a small mud flap in front of the tire to cut air around them. i saw the same thing on a new mazda 3 today too so this must have some effect on aerodynamic.



GTR has a really similar hood as our 2ng gen hood and we might be able to use the vents from gtr on our hood. got to do some measuring, unless someone here do it before i do it. little to no drag and still having ventilation.


all that plus making the car lighter.
The flaps in front of the wheels is to provide more grip. So that the wheel dont have to roll over a cushion of air. I think the air resistance would be the same as far as aerodynamics.

Also those are intakes not vents on the gtr. If you where to put an intake on the hood i would place just one of those in the left lower corner to provide fresh air straight to the intake. Then a vent or two on the top position of the hood(hot air raises). Like the two vents on the 575 hood.
