Default Will 17" Cups Fit?

Will the following Cup's from a 964 fit on a 85.5 NA?

Front: 7 ½ Jx17H2 ET23
Rear: 9Jx17H2, ET15

Any advice would be helpful. There used to be an offset chart around here somewere but I've lost the bookmark.

Those look like the aftermarket wheels that will fit an early 944. They are not from a 964 as it's offsets are in the 50-55 range.

Seller stated they were Mille Miglia's from a 964. Wanted to know if I should bother to go look at them.

You should still be early offset so why not?

Those are early offset aftermarket wheels which fit 1986 and earlier 944s. So yes they should fit your car. He must have used spacers (pretty thick ones) for his 964.

It's actually going the other direction. A 7.5" ET23 front wheel will stick way out on a 964. The stock 7" ET55 wheel from a 964 will go on an early offset 944 with a thick spacer.

Those 17x7.5" ET23 and 17x9" ET15 Cup replicas are actually pretty common/popular. They won't go on a 964. They will go on '89 or earlier 911 and early offset 944.

If spacers are needed to put these on a 944 what size would be required?
Thanks: Jim

these are the same size and offset I have on my 85 944. Fronts fit fine with 225 tires, rears ""just"" rubbed with 255 tires and factory spacer (early 85). I replaced it with a 1/2" spacer and now its perfect.

The owner states he has the following size tires on the Cup II's:

Fronts are 205/50 ZR17,
Rears are 255/40 ZR17

Any interference / rubbing issues?
