Another Offset Question

[Patton]

I have a set of 17" Kinesis Super cups that came off a car that I wrecked last year. I would like to get them on my 87 930 body that is my daily driver. My car is lowered and with the current 315/35 Dunlap tires, I'm into the fenders. The rear wheels are 5-1/2' inner and 5-1/2" outer offset. Is there any chance with a different tire size and raising her a bit that I can get these wheels to fit? Otherwise, I may have great set of wheels to sell.
