Hey guys, I'm hoping someone can help me here, I'm after the size of the center bore (on the hub side) of BA XR6 17" rims...I'm assuming they don't use a hubcentric ring as standard and are matched to the ford hub size..but have conflicting info. Some info Ive seen is that the center hub size of a BA ford is 70.5mm on the front and 71.5mm on the back.. Not sure if this is correct as that would mean there would be two different center bore sized rims for front and back? Anyway, aside from that I just want to know what the size of the hole is on the inside of the rim. The reason for this is that I want to get some hubcentric/spigot rings to drop the size down to 66.1mm for a diff application. I think it should be 70.5mm - but if someone has some concrete info or can measure it, that'd be awesome. Thanks
