Would anyone out there know the centerbore on the SSR sp1 Professor wheels? I'm looking to get some hubcentrics rings. I already know what our car centerbore is but have scour the net trying to find out what the specs or measurement for the SSR SP1 centerbore is? I have measured it with a digital caliper and it comes out to be at 74mm. I just want to double check if this is correct?

Thanks in advance if someone knows.

 

if you measured it yourself then why would you need any other info to back it up?
