Cover but don't touch? How much gap?

How is balancing handled?

A materials question, is there galvanic action between the steel platter and the alloy wheels? As a quick 'sanity' check, you might consider a test with a salt solution soaked wash rag and the cover and wheel. Use a VOM and see how much potential is generated.

Generally speaking, two metals in a salt solution become a battery and one will 'sacrifice' itself. If the sacrificial part is the cover, good. If it is the alloy wheel, not so good.
