C5z backspace Q


have a 67 A body that when the mood strikes want to run some 17s...
a 17.9.5 or so will give me the rubber I need out back, may need a 5 in bs though. What spacer (dread them but for 1 day, track only....)
17x 11 will tuck wiht a 315 but a little too tight.
Suggestions?
Currently run a 15x8.5 with 275/50 MT...and its tight (4.5"bs)\
Fronts I can squeeze a 265/50/15 but again, tight. For now its pizza cutters...just want something affordable for days I want to go around corners fast.
