i want to put st3 alloys on my mk1 focus is there a way of doing this with hubs or is there any companys that do the adapters?

 

Best way to do it would be to take your hubs to a machine shop and have a second bolt pattern drilled. The thinnest adapter that I know of is 25mm. Not sure of the offset for the ST wheels but with that tall of an adapter you'll probably get rubbing problems.
