Torque thrust 17x8
With 27mm offset which is a 5.62" backspace.

Overall tire and rim height 25.68"
Tire width 9.64"
Keep in mind a 8" wide rim uses its outside edge to outside edge measurement of 9 inches to calculate offset or backspace.
I
Ive test fit one rim and tire setup on all four
Corners of my car. The front fit fine with plenty of room all around.
The rear fit good, a hair tight near the leaf springs. They will never rub
I only needed a 3/4" offset . I had to go with the 27mm/1" offset to stay
Away from the more expensive 2 pice rims.
I also had wanted the 18x8 rims but they were not
Available in a offset I could use.

hi kbsouers,
your combo looks good! (on my '68 b-cuda) I was thinking using 245/45/17's or 255/45/17's on a 17 x 8" (all 4), with 5" back space(most back space offered on this wheel). pretty much same brakes you have too. (Dr. Diff 11.75" disc fronts & 10.70" rear disc, 5x4.5 axles)
does it look to you that if you added a 5/8" (.62) spacer, (in other words moved things outward on your set up) that you might have fender clearance issues?

Thanks!
Dan
