Offset question

[PlmCzy70]

does any one know what the offset was on the factory Chrysler Ralleye wheels. I’m going with 275’s on the rear so I think right around 0 mm would be best. I see a lot of the cars on the site have the rally wheels so if you do, what’s the offset on yours?. my car has no mods at all.

5.5-inches seems to come to mind as the standard offset for most E and B body wheels of this era.

I’m assuming you mean backspace when you say 5.5 inches

I do and did. It was the only "offset" I could think of, the back-space. But Challenger RTA's data (posts #4 #5) suggests its 4.5-inches.
