well about the fender vents. idk about reducing drag but it im guessing by allowing the air in the fender a place to escape it pulls out the hot air from the fender and allows more air flow to the brakes.

and as far as reducing turbulence again im just guessing but rather than having the air just push out of the wheel well with no place to go is worse then having a specific place where it all flows to. how far did MIT or MTI go with wind tunnel testing?


as far as aero goes look at ferrari aero. full underbody aero trays, vents and scoops in certain places to smooth airflow and reduce drag and increase down force.

if you really wanted to have much better aero, go to home depot and custom make a gurney flap out of door sealer (a line of rubber to keep the cold out) and get some aluminum sheets and make a full body undertray, cut out a few ducts on the rear of the bumper or use the nismo bumper with the vents. and your car will be much more stable at speed. the lower the car the less air that gets under it as well.
