what is this number mean?

Kind of like this rim http://www.jic-magic.com/ViewP...ID=81It's similar to greddy gull frame, but it is more friendly offset. Unfortunately, I don't know what does the the number in the HUB column = 73 mean.Usually I saw 5 x 114.3, wide, offset for the tire spec., but not this number. Will this wheel with this number(73) fit with s14?

That is the hub bore diameter in metric.The hub bore for those wheels = 73mm. The OEM hub bore for most nissans is 66.06mm.

Most aftermarket wheels have a larger hub bore to allow for a wide range of vehicle fitments.

I thought my thread was dead already. Nobody answer it like 4 days.If those web page just put the word hub bore, it would be easier to search.Thank you so much. big appreciate!
