I'm not sure there is such an animal. If these are the wheels you want to put on a Z. The stock backspacing is only about 3.5" to maybe 4" at the most ( to the best of my knowledge) so that would mean you would need something on the order of a 2" to 2.5" thick spacer/adapter! I'm not sure that even if one could find such a spacer/adapter that it would be very safe to install. If I'm wrong I hope someone will correct me.
