I also hope you used hubcentric rings. Looks good, other than needing to be dropped, if you can without rubbing. Can you post a daylight picture showing how they line up against the fenders? Thanks.

More in depth explanation of what hub rings are and what they do:
Your wheel has a, more or less, female hub and your vehicle has the male hub. Ideally you want the hub on your wheels to fit barely over the hub of your vehicle. (within .01mm) If they don't fit this tight you can actually torque them down off center which will cause a vibration and can lead to other problems while you drive. There is no industry standard for hub size. Scion uses a different hub size for each of their vehicles. Honda uses different sizes and so does Ford and Chevy for that matter. Most after market wheel companies want to make their wheels so they fit as many vehicles as possible so they build their hubs large enough to fit the largest vehicles hub. They then include or sell hub rings to fill the difference if your vehicles hub is smaller. EX: Konig uses as 73.1mm hub size for most of their passenger wheels you would need a 73.1-60.1mm hub ring for your 08xb.

I hope this helps and doesn’t confuse you more.
