will they fit? 86' 951

I've gotten so many different opinions on this setup I don't know what to believe. Unfortunately myself and my car are separated by 1500 miles so I can't go out a measure myself right now either.

Front:
255/40R17 Kumho Exsta XS
ZR1 17”x9.5”, 56mm offset, 5x120.65 bolt pattern
Final Offset to be: 35mm
.827”, 21mm spacers needed with a 5x130mm to 5x120.65mm bolt pattern conversion

Rear:
295/35R17 Kumho Exsta XS
ZR1 17”x11”, 50mm offset, 5x120.65 bolt pattern
Final Offset to be: 25mm
.985”, 25mm spacers needed with a 5x130mm to 5x120.65mm bolt pattern conversion

Being an 86 I have early offset, right?
I've got Ground Control Coilover conversions on front 440#, 180# rear. Lowered some, I'm taking it in for an alignment after I put new wheels/tires on so it could change if needed.

I can't tell you for sure if they will fit, but can give you my specs and you can go from there. My car is a 944S but I am running early offset in the front.

Front
17x9 cupII wheels (55 offset) with 32mm spacers. Tires are 275/40-17. Lowered and -3.25o camber. I cannot really go much wider than that setup on the front, maybe 5-7 mm.

Rear

Same wheels and tires as front but running 15mm spacers. -2.5o camber. This is a very tight fit and in fact I rolled the fenders ever so slightly to make it work.
