Whats the best way to go about cutting these small holes the racing bugs have? Some look like they have been drilled out others look like they where pressed out and have round edges.

I want to do this for the front valance to get air to my radiator, will it need to be removable panel?

electricians have hydrolic hole cutters, i've seen manual ones too, come with a set of different sizes.

had a peek on e-gay, $325 gets you a set.

Thanks for that vwjon, so will that give me the holes with the pushed in rounded edges?

speed holes.. ask homer 😉
I have pressed similar ones in my decklid
pressed out not drilled out so maybe like a big piece of machinery would be involved
the link above could be the go thou
goodluck

Hole saws.

But plan out your hole pattern very carefully with minimal material in between.

I did that with mine originally but slotted and whilst it worked well I did see a noticable reduction in highway temps when i opened up the whole area and put the mesh in.

Same deal with my spoiler, looked good but an open square with mesh works much better and lets heaps more airflow through.

Thanks guys, I think the machine above might be the way to go, maybe I can hire one, but in this pic the holes look rounded in, (like the homer method)

I hope you can see what I mean I can only post pics in small medium is to big to load.

They would be cut with a hole saw, and then pressed with a dimple-die to create the rounded edge. This also gives the metal its strength back.
