There is a guy selling in my neighborhood selling a set of Porsche wheels for a discount price, I am tempted. I think they were on a Boxster at one time. Is there any chance they would fit on a 964 with Bilstein/H&R green suspension? What spacer would I need for this?

The fronts are 5x130 bolt pattern, 17x8 size, ET 14 offset
The rears are 5x130 bolt pattern, 17x10 size, ET 15 offset

 

These wheels are for the pre-ABS cars, i.e. 3.2, and will not fit a 964 (or a Boxster). The offset (ET) is far too small and cannot be fixed with a spacer. A spacer will only REDUCE the offset, not increase it.

Thanks!

 

How about these, will they fit?

17x8.5" et50

17x9.5" et50

 

Yes, but it will depend on tire width as to whether or not a spacer is needed.
That's a nice combination and one I've been considering. Perhaps in 18's.
I have 17x8 ET52 no spacer, and 17x9 ET55 with small spacer ~3/5.

 

Will these wheels interfere with the control arms on a standard (non-RSA) 964?

 

No. The C2 and RSA share everything the same. Depending on your choice for the
front tire, you may need a steering stop. As yet, I've not needed such, but some here have and can help you with their experience.
