Or a CB design wheel 

Hillman Imp should be Minilites
Porsche 911s should be Fuchs

So insert wheels only.  I will not be running an Imp or 911S it was solely for an example.

I think I am beginning to understand your issue now, yes machined wheels with integral "hubcaps" are allowed, but should be of the appropriate style for the car /era.

I have amended the rules above to clarify the point

W2) All wheels must have appropriate style inserts fitted at the start of each stage or alternatively they can be machined wheels including (hubcap) insert design
