Does anyone know of an ATV that uses a 4 on 4" bolt pattern hub connected to a cv axle? Thanks for any help, I am trying to find this for a small race car I'm building.

 

Im thinking they mostly all are metric, but i could be wrong. 4 inch is gonna be about 101.6mm, Some of the older polaris were 4 on 4.
Heres a link to a chart which shows which models and years have what.

yes the polars trail boss 4x4 gasm 4/4 weel pattern

 

I think the 4/4 on the polaris was only used on their straight axle machines. I know this is not what you asked for but, I could get you a set of 1" or 1.5" wheel spacers that could change a 4/156 to a 4/4 but it my be cheaper to buy new rims. They go for $100.00 a pair.
