Ok I've search and can't seem o find a clear answer on this
I'm shopping for some wheels for my car and want to make sure I have the right information regarding hub size front and back

• - What is the center bore size at it's thickest point for the Front hub?
  - I see it tappers down right away what the diameter after the "hump"?
  - I noticed many grind the hump down how much can be removed safely?
  - What is the center bore size at it's thickest point for the Rear hub?

This is for a 67.5 with standard brakes if that makes a difference

Thanks in advance

Anyone?

A quick search in this forum seems to bring up 73 MM and talks of machining wheels that need it to that range.

I’ve read both 73mm and 76mm and wanted to make sure

73 looks like an absolute minimum- might not seat all the way on the hub unless there is a chamfer on the inner bore. 74 probably safer bet.

Specifically several cited 73.1mm I am guessing by JT's comment that .1mm Makes a difference.

I am sure the front hub is 76 mm. The reason some 73 mm concentric hub wheels fit is they have a bevel that increases the bore at the wheel mounting face and the hub lip is very shallow.
The rear does not have a concentric unless you are running Z car drums.

great thanks everyone
