I guess the only improvements i see are wings and diffusers for downforce.
But i see this as a wank/rice factor than anything else..You wont even notice anything.. I feel anyways!! for normal street driving that is..
I think nissan did a study on the 34, before it released its gtr: on what wing to use and im sure they did a vast study on difusers.
Diffusers are great to minimise turbelance(sp?), and i guess it would cool the diff as well.. So will be worthwhile upgrades if you ever need it!!
However, im sure professional track car drivers would have thought of aerodynamics, but lets face it.. Skylines arent like F1s and arent state of the art!!
Also comes down to money in the end.. Most of us couldnt afford to put it in a wind tunnel and test it out hahah..
Actually would be cool if someone has actually done a air-velocity test on a skyline..
However, with most huge bodykits ppl have, its gonna increase the drag.. LESS drag=GOOD!! lol
another point i should note is that, less resistance in front the wheels will aid to improve less drag.. I dont think we can do this in the skylines lol..
For example look at the f1s.. They got nothing in front of the wheels.. less drag!!
Anyways i wanna know as well if anyones done a study on this.. esp on skylines..
