Who makes the best off the shelf discs? its for a conversion so they'll be getting re-drilled and centre bore.

Everybody.

Unless you are getting ceramic or steel discs they are basically plain old cast iron, and the most significant difference between brands is the box.

While you're getting them adapted to your hubs please don't cross-drill for ventilation or anything daft like that.

do none of them do curved internal veins?

I'm not cross drilling or similar. I would like 4 groves like the cp g4 range https://www.gartrac.com/shop/ap-racing-vented-brak...

I would have thought not all casting's are equal?

I want quality discs that will last on trackdays and possibly the odd hill climb.

I've new ap cp5040 calipers to use. 1155 pads.

Yes, bells and discs are 'easy', however £270 for hubs, £430 for ap discs, £30 for mounting bobbins, so £730.

Or find the very best discs I can that are in the offset/diameter/thickness I need, then pay £20 to have them centre bored and pcd changed.

These are conflicting requirements, because you will need to cope with sustained heating on track days, but on hill climbs the brakes will barely get warm.

Yes but quite a common thing. given my relative lack of speed up a hill its not a major issue!
