right now i have 14 inch cragar ss wheels on my 84 pontiac firbird. they look sweet as hell on the car but i want bigger ones. Does anyone know the max backspacing on the 84 firebird?

Someone else posted this on here for me..... but you gotta know the stock back spacing first.

The backspacing of the stock wheel? I just need to know the max back spacing the car can take before the wheels hit the wheel well or something else. I dont want to do it the way the tech article says too if someone already knows. Thanks

i dont have the original wheels on my car so i dont know the offset and backspacing. If anyone knows the original offset and backspacing for the original wheels on a 84 pontiac please let me know.
Thanks,
Jordan

I don't really know what the max size/backspacing is for a bird... But I just went through this with my Charger... I ended up special ordering some 15x10's with 5 inch backspacing for that.

You can special order whatever backspacing you need thru Summit... but it costs more. $159 actual versus the $134 advertised price in the catalog for 15x10's.

Here's the place that actually makes them: http://www.cragarwheel.com/
