I would like to know whether it would be worth having a small angle on that lip. Imagine a doubled ply edge under the factory lip to give it a sloping front. Common sense says it would catch more air... but it would be nice to be able to adjust that via the suggested threaded rods to assess the right amount of downwards angle.




If there's too much downward angle you'll get flow separation on the underside which causes drag but you'd probably need to angle it a fair bit to get to that point. If you look at splitters on purpose built car cars (Le Mans cars etc) the top surface of the splitter is flat so air pressure is acting perpendicular to the road.

Check this for an extreme splitter. Difficult site to get around but there's some good info on there.
