Wings?

[George16]

They help in keeping the truck level in the air (my experience). It's also a good place for a marshall to grab your truck.

I don't think he's asking if they work . . . I think he's asking for our opinions on whether or not the different styles make much of a difference. Like the Pro-Line high downforce or the regular. Right?

My experience is that they don't make a huge difference in performance unless you change to a high speed true 1/8 scale track. When you're running around 30mph average on a track I don't think there's too much difference from one wing to the next. But I don't know for sure.
