are there any body kits that actually improve aerodynamics?

long nose/long tail designs typically offer reduction in overall drag coefiicient and greater stability at high speeds.
for time attack/time trials, companies will always retain fender well covers and front/ rear undertrays whenever possible as to help with aerodynamic efficiency/airflow underneath the car, while placing canards, splitters, wings, gurney flaps, air channels on top to create downforce at specific SPEEDS.
to reduce front end lift, and steering looseness at higher speeds, you'd want canards and a front lip that can produce further than factory nose. the steeper the canard angle, the more drag you'll encounter, but more nose down force.
if u feel like the rear end is too lose on turns at high speeds, place wing high enough in the airstream to actually push your tail down. Thats why you see all the race cars with super high salad bars.
not many people realize alot of your airflow underneath the car also comes from the sides of the car. lowering your side skirts closer to the ground will help prevent air from wrapping around and going underneath the car.
typically for the underside of the rear of the car, once u remove our stock muffler, that bumper acts like a parachute it will catch the air. if you can, seal off the back of the bumper or like in some of the rear bumper designs that are coming out now, they're putting holes/ mesh to allow the air to escape. (think the Arising Varis rear bumper)
Cwest and Spoon and nismo are the only ones that i know of that are truly Wind Tunnel tested. alot of the smaller body kit companies just can't afford the thousands of $$$/hr a typical wind tunnel will cost for development. Most of their kits are track tested and tqueaked accordingly.
