Yeah, I've heard around 40 mph is when it would start to make a difference. But more than lifting the front of your car as most people think it does, a lot of people say the car feels more stable at higher speeds.

 

I don't think that the result is lifting the front of the car... Due to air flow, the effect is a push down on the back of the car - stability, yes, but not that hard or sudden for the front to be lifted, think that the engine is there and it's quite heavy, I never heard before that wing effect (whatever car used).

Also, since this is my first post, I want to say hello to everyone, I'm reading this forum for quite some time, you have very interesting posts and ideas here, keep up the good work...

 

wait doesn't just get added without taking some away though. my theory and im sticking to it

 

I was agreeing that it doesn't lift the front up. It just pushes down on the rear.


That makes no sense. It's "weight," and how does that work? If you add weight, you add weight. If you take some away, that's all you do. They don't have to be together.

 

if something is pushing down on the back obviously weight will be taken from the front. think about how your car feels when you have something heavy in your trunk and you try to take off

 

I think it just pushes on the back. You aren't adding any "upforce" on the front. So the front still would weigh the same. When you have stuff in the back of the car, the front still sits at the same height.

 

FYI, on wings. For them to be effective, speeds must be around 80mph or higher. Attached you will find data on the APR GTC-300 wing. I know its not the Evo wing but still should give you an idea of when downforce actually comes into play.
Sorry its so blurry. It was hard to resize an excel file to JPG.
