i would think anything that makes more air go under the car is bad at speed, the idea is to have all the air go over and push the car down.

i would think the floatyness in turning could be soved with a wee bit of left foot breaking, but it's really not good. I wouldn't drive anything at speed if it felt like that. As is our highway allows me to take the datsun out and open it up to about 80% and not even be speeding, adding the front airdam was such a good thing, the current setup feels real stable at 150 kph.

hehe isn't that fun... for some reason you can go at least 105 kph all across the country. often much faster. Yes an A15 can do it too... At 115 kph or faster easily.


I've noticed something else re: airflow... I have a big hole in the boot of my car, about 3ftx2ft and it's covered with a piece of cardboard, strapped down, if i'm going faster than 100 kph, and have the windows down much air starts to come in from outside from the back... yeah i know that's not a good thing, what sorts of things can be done to make more downforce? having a bigger cavity where the fuel tank was would allow the airflow to slow down and pull the back down more? what about airdams and such for the rear, or do i want to make the rear more open?
