The rear spoiler actually does something!

In the snow today, I noticed that after driving for a few miles, the half melted snow on the roof had been pulled up from the back of the roof by the air pressure created when driving. Like I had another snow spoiler on the roof, about where the aerial is fitted.

So I guess they actually do create downforce then!

Blimey!

being a cynical old git I just expected it to be for show only.

So there you go, you can sleep easy tonight everyone!
