ah yeah that clears everything up man. you won't really need one at all. we've made our own lips before though.



those are the kinds of lips rally cars all have, and that does the job. when i installed my lip, i noticed air turbulence was a slightly better, but then i just lowered my car wink1.gif

lips are different. they keep air out from under the car where it causes turbulence and drag.

the thing alex posted is a splitter. it directly creates downforce on the front wheels.

Rear spoilers on some cars can have a huge effect on gas mileage. They correct the air flow over the car for less drag.
