Hi all. I have an Aussie imported 2001/2 Mustang Cobra and when I bought it the wheels were California rims and 18". They sit too far inside the guards. For now I used spacers to try and fill the guards out more. What I need to know from you all, is what 18" wheel offset dimensions will fill my guards without using wheel spacers? I want to fill the guards up lie the wheels in the pics. Mine is the blue Cobra.


Thanks in advance....
