What do they mean by ADR markings? There's plenty of Cobras that have gone through rego with aftermarket wheels. I know of no ADR number that needs to be on there but I'm willing to be re-educated. There are some numbers that give the Rim Width, Bead type, PCD etc. Would you be able to measure and check these yourself and then mark the rim accordingly?
Here's an explanation of the numbers.
