Thickest whee spacers/adapters for original 15' rims?
 

Hi,
I have a 1980 Vette on original 15' rims and want to make the rim offset more agressive.

Question - what thickest spacers can i use and avoid wheel arch rubbing?

Thanks.

If you go bigger than 1/4" will need longer wheel studs.

I consider longer studs as a default.
