Doug,

If you search for the Rennlist member 'AO', Andrew has a wheel fitment calculator in his signature. You can plug in your figures and it will tell you your answer. I plugged in your numbers. Fronts will fit. Rears will need a spacer.

Do not forget , with 50mm front offsets ( 928S4 needs 65mm) that's 15mm per side offset difference , which in turn changes the scrub radius quite a bit & this will make the steering ( on a 928S 86> / 928S4/GT/GTS ) very nervous / tramtrack etc

We see quite a few 928S4 etc with 52 mm offset front wheels & there are quite disappointing to drive to say the least compared to correct offset

Thanks for the good info. I think I'll wait for a better fit.
