Chamfer degree of Hub
 

I am trying to get some custom hub spacers made, but the machine shop would like to know what the chamfer degree of the hubs are.

Does anyone have this info? Thanks!

EDIT: I checked and the hubs on these cars are not chamfered.

no idea that spec exists online, but couldn't you just take the car to them and have them measure it in person?

Unfortunately, they are not local to me.
