how much offset

Hi guys I have an '87 Formula with factory 16" wheels and disk brakes. I want to run 245/45/17's on the front and 275/40/17's on the rear. Can you tell me what offset I'll need on the front and on the rear. Also will I have to run a 10" wheen for the 275's?
Thanks
Bob

For the front, get an 8 inch wheel with 4.5 inches of backspacing (sorry I don't know offsets). For the rear get a 17x9.5 inch whel with 5 inches of backspacing. This looks awesome, my buddy's 92 z had american torq thrusts with those measurements, and it was just right.

Thanks for the info. I guess I thought offset and backspacing were both the same thing You gave me what I was lookin for.
