I have a set of these on my car at the mo 13" x 5.5" ET?
I'm wanting to change to a more modern style (Minilight or similar), the only problem is I want to keep the same offset as these originals as I have built all the suspension around them (not knowing they were 5.5" instead of the more desirable 6"). There is nothing written on them regarding ET numbers so I have taken a measurement from the mounting face to the outer most rim bead (back face) and this is 100mm. Can anyone point me in the right direction on what offset this is and what type of wheels I may get to meet this requirement.
