I've been over the topics and can't find anything specific to this. I really like the look of the rear valances with large holes. I presume this is done to save weight. I don't see that it saves much weight but I think it just looks great. Pic attached. I'm wondering if you can buy a valance like this or more importantly if you can cut the holes whilst the valance is in position? Has anyone done that. In the pic the edges of the holes look bent over and tidied? Can anyone help me with advice as to how to achieve this look?

Cheers

I believe the hole are made with dimple dies, doable in situ but as the valance is curved it might take a bit of panel work.
Painting will be inevitable.
On a second note, apart from weight loss, it also reduces air resistance. Not that you will notice it much.

Holes in the valance are fine if you like that look however if this article from Mini Tech News is correct then don't expect a reduction in drag but rather a massive increase.

thanks for that its actually really good reading. As I said I just like the look I'm not that bothered about drag or weight as the car isn't a racer just a fast roader.

Simplyminis did it on the A panel, check it out.  They'd be the person to ask.

..as MacGyver points out, the valance is curved so normal dimple dies won't work.

 

you could try and get dies made up to match the curvature of the panel, but i'd imagine that would be quite expensive....

I believe he's also the 'valance guy' 😁
