Wheel Hub diameter

This site may earn a commission from merchant affiliate links, including eBay, Amazon, and others. receipt with DTD says they will ship me a TSW 76-70.60mm centering ring, but they list the Boss as having a 70.70 hub diameter...

Can anyone verify that the actual wheel hub or center bore diameter on the Boss is 70.70mm? So far I have seen people say 70.4, 70.5, 70.6... Companies that sell spacers list all the way up to 2010 as having a 75.0mm center bore. So someone is full of BS. For the BBS, SVE Drifts, Enkei, etc... what ID rings have you all been using? It looks like 70.5 is correct, but I want to verify before having DTD correct the order.

PS: I ordered 18x9.5, 40mm offset Interlagos.

Thanks for any help!
Wish I could help but I just called Luke at TireRack and asked for the correct ones that fit the Enkei PF01s and he shipped them to me. My receipt just says "required centering ring". If all else fails I'm sure you could contact him and get the correct ID from him:
LUKE (EXT.4362)
