Im ordering the C6 motorsport rims from TomZwheels next week but I need to know what spacer I will need for the rear 19in rims? Also, what tire size should I go with? This is for a 2000 SS M6 lowered with prokit springs.
thanks

 

These are reproductions right? Don't they sell them with the proper offset?

 

not from what I have been told. These are aftermarket wheels correct.
