Little help figuring out B/S for billet wheels

Edited: 12/31/2010 12:30:35 AM by polski13

Hey guys,

I'm considering switching to some billet wheels for my build, but I'm not sure how to know the back-spacing to order them. My chassis is completely one off, and was designed around the wheels I currently have and I'm not willing to redo the whole thing, so I'm hoping someone can help me figure this out.

My current wheels are sized as follows:Fronts 22x9 - 40mm OffsetRears 22x10.5 - 25mm Offset

The wheels I would be getting are Intro Twisted II in the following sizes:Fronts 22x8.5Rears 22x10

How do I determine the backspacing I would need for the Intros, since they are different widths?

If anyone is willing to lend a hand, I'd really appreciate it.

And if you're bored, feel free to take a look at the build: http://www.facebook.com/home.php#!/album.php?aid=421385&id=202628160161

call intro, tell them what kinda truck youve got and what your wanting to do.

i called them cause i wasnt sure either and they faxed me a sheet with a simple but specific suspension drawing for the front and back for what and where you will need to measure to ensure your getting what you need.
