I'm going to bend the cycle wing carriers/brackets today as my mate is in his garage with his big vice. But I'm not sure how far above the tyre the bracket should be? I'm using Indy wings if that makes a difference. I was thinking somewhere between 15 - 25mm??

25 mm or 1 inch is about the right amount - remember that at speed the tyre is forced outwards due to centripetal force, not a huge amount but will matter if your gap is too small..

what peeps do is to tape block of wood to the try then put the wing on,

5mm is fine, well it is on my car

Don't forget that if the clearance is too small you may not be able to remove the
wheel without taking the mudguard off.

Better aerodynamics with the arch as close to the tyre as possible , reduces the amount of lift on the front end IIRC plus it looks better IMHO

You can always tilt the wing forward so more coverage of the tyre is increasing aerodynamic efficiency. I used just enough to remove the wheel. Blocks of wood did the trick.

It's always worth remembering that a seven-style car has the aerodynamics of a house brick, so practicality is more important...
