Kosei K1 centerbore question

[Ludachris]

I know the centerbore on our cars is 67.1mm but does that mean the Kosei K1 17x7.5's I have on the car have the exact centerbore, making them hubcentric? They appear to fit tight to the hub (and the protruding ring on the hub) but I didn't want to assume that they're the same size. I only ask this because I'm having some spacers made up and the guy asked what size centerbore the wheel has, as opposed to asking what the centerbore was for my car. I realized that the wheel might not have the exact same centerbore size. Of course I don't have a good device to measure, but the measuring tape does come close to 2.64" which would be 67.1mm.

Any feedback?

I run 15" k1's on my rally car and they came with plastic rings...

Mine have the rings too, that must mean the rings adapt it to the correct centerbore. Anyone know what the centerbore is for these wheels?

If no-one answers within 24 hours, I'll take a wheel off the car and measure it for you. I can't do it today. Sorry.

No need for you to do that - I can get my lazy butt up and go to Home Depot to buy some measuring calipers and measure it myself. Now I'm assuming the inner bore where the rings sit is the measurement I'm interested in?

Had a better idea - called Tirerack since I know they sell these wheels - 73mm.
