Does anyone know the wheel offset of the standard 17 inch or 18 inch wheels that came stock on the XK8? I'm researching aftermarket wheels.
Thanks for any info

 

I use this site to check for wheel specs,and to compare other options. You can check by make and model, and the specs will show in the topmost area. They also have a page you can reach using the menu on the right for size comparer.
