Rovers with Spoilers?

[TimePeriod]

I've just learn form experimenting with rovers and wings that my rover will have a marginal top speed increase if I add flaps to it as it accelerates. Anyone else could tell me more about this?

I don't think spoilers really help in KSP in their truest sense. They are the little ramp-shaped thing on the back for disrupting (spoiling) the laminar air flow over a car, reducing the "lifting body" effect and giving it better handling. And Kerbal rovers are rarely streamlined or even fast enough for that to be a problem.

But if you're talking about a wing, that's a different story. Some people (who are wrong) call them spoilers, but they provide actual downforce. I can see this working as long as you can get KSP to simulate downward lift, and I have no idea if it does.

Please elaborate further.

I don't really get it.

Long story short, in KSP more downforce = faster wheels.

Using aerodynamic parts is one way. RCS on Mun is also rather effective. (use an upside down probe core so that in docking mode W will push you down as well as making the wheels go forward)
