Hub Center Bore

[ArcticSS]

Correct me if im wrong but is the center bore on a 2000 camaro 70.3mm. And isnt it just a tad bigger in the rears. Im looking to get some new rims from american racing and it says its center bore is 72.60 with a 45mm offset. On the website it says this would fit camaro's but i dont know if it needs an adapter hub ring.

Im looking to get the 17x9 ones in anthracite.
