I will be fitting a big rear wing to the roof of my car shortly, but it doesn't have any end plates on it, is there anything I should be aware of i.e size, shape? I don't know if I'll make them with aluminium or carbon fiber yet.

Make it match the shape of your rear arches! I have no idea whether or not that's a good idea from an aerodynamic point of view. Got a wind tunnel handy?  |

Seeing the edge that will be "in contact" with the air, and therefore any resistance, is minute then I reckon you can freestyle whatever looks right as doubt there is any rules for the side design.

Something large and overstated like this!  |

Hi, The idea of the end plates is to make the air go over the profile of the wing, the air will want to wash off the side of the wing because that's the easier path. This principle is why commercial aircraft have winglets on the end of wings but in their case it for more lift and fuel savings. So you could do worse than look at the shapes they use to save experimenting in a wind tunnel. I would think in your case an arrow shape pointing forward would be best.

What actually happens is, as the bottom surface of the wing is at a lower pressure than the air to the side of it, the higher pressure air flows into the low pressure area under the wing. The end plates prevent this from happening.

We all know it's got sod all to do with aerodynamics, is cos they look cool as you know what!

Looking cool is a matter of opinion, controlling air pressures is a matter of fact :-)

It's all a bit beyond me, so I'll stick to looking cool!
