Help with getting the proper offset (with KW arms, toyota spindles and RX7 IRS)

im running a 5" back spacing, its really tight,5.5 is the one everyone recomends on a 7" wide wheel, on an 8" wide it would have to be 6.5" back spacing, i think, ive people run old ford courior rear ends, and using an 8" wide wheel the axel is narrower and on the front the camber will allow the rims to tuck

haha well, that would work from a stock mazda with stock suspension, but I dont think you read the post.

Corey, you should change the message title of your first post to reflect your KW/toyota combo in the front and the RX rear, so people know exactly what you are asking before they "open" the post to reply.

oops, i didnt read that far, my bad

ok I hope I edited that properly now.

i have your front set up your talkin about. and i have about 2 inchs of offset to play with........but to be smart. just run normal FWD wheels they look fine. and im not sure how much that rx7 rear will suck you in.......but here is a sneak peek of how much they sucked in
