Rear camber adjustment shims
 

Can they be made by a good machine shop?

The reason being, with low availability aside, is that they're between £30 and £40 off the shelf and it seems a lot for just a bit of flat metal. With VAT and delivery it's going to be about £100 just for two.

I can't see how there would be any difference between what I could order from SNG or BP (and special order even then), and what I would get by going to a metalworking place and giving them some measurements. I expect it would be loads cheaper too.

What are the thoughts about this approach to the rear shims? Is the type of metal important - is mild steel ok?

I guess it would depend on the thickness you need and the thickness that can be used by someone to cut/drill the steel.

The steel spacers are .5mm increments and I have found that the 4mm (commonly found factory fitted) can be replaced by a 6mm to get the camber back in spec 'most of the time'.

A 1/4" piece of steel is about 6.4mm so it might work and that is fairly common here in the U.S.
Can you find steel thicknesses in the needed size????

I would guess mild steel is OK because the material is under a compression load and it should hold up.

I have a machine shop that made me shims for my X300. I can get you shims just let me know the size... $75 each.
