SCCA rule re: wheel sizing in stock class

[bren]

It seems like the only way to get the rule is to buy the book, is this online and I just can't find it?

Anyway, I have been looking at various wheel options but I'm not sure what the requirements are. I imagine that stock diameter and width are required, but what is the allowance for off-set. What happens if there are different wheel sizes available for the same car, can I go with either size?

For Stock classes...

Same width/diameter as OEM from the factory and offset +/- .25" from the factory wheels. If the car could normally be ordered from the factory with whatever particular wheel size, you can use that wheel size. The only caveat is that if the wheels came as part of a package, you have to have the entire option package.

I noticed a couple of serious math equations on the forums today. :(

Don't worry I found my answer 6.35mm

Is this in relation to a mythical M Coupe or roadster?
