The wheels in question are Konig Rewinds and are 15x7 +0

I know wheels can be re-drilled to accommodate a different stud patterns and has been done with these wheels before on an mx5.
What are your opinions on this? Are the wheels strong enough to take it without compromising the integrity of the centers? Have any of you tried?
Nobody tell me that this is not done because I've seen it before.

that is what i'm aiming for!
Where can I get this done in Melbourne and how much will it set me back?
I've been reading about re-drilling and how specialists will put some metal bit into the original holes, weld over and sand back then repaint
