I've been playing around with different offset wheels in my head to figure out my final desired combination. I currently have a C4/C5 Corvette disc brake set mounted on some turned down 69 Camaro drum hubs. Am I recalling correctly, are the Camaro and Firebird hubs different? I seem to recall the Firebird having a wider front track due to the hubs, but can't find something to confirm that. If you know of a difference and how much, please let me know.
