Question is will the new ones fit without rubbing
One concern is that the calculated difference in Circumference on the New front/ rear tyres is app 3,8 %, will that influence ESP and ABS??
I think that barthol is looking for info specifically about fitment of that size and offset, and I know we have people here who can answer that.

Sadly, I am not one of them.

I will offer more unsolicited advice though...

The issue with the early Boxsters and wheels larger than 17" mostly has to do with the rear sub-frame brace. On the 1997 and early 1998 cars it was weaker and prone to cracking.

Like it was said earlier, you'll have to get it realigned after you replace it. Might as well upgrade both while you're at it. I sell them for $50 each plus shipping. The beefier rear subframes break easily, just not as easy as the early ones. The front subframe is slightly different on the early cars too, but I've never seen anyone break those easily.
For wheels I like to check here for info: 944racing
But the information is incomplete for those specific wheels (Boxster S II).

Hopefully someone who knows the offsets and fitment better will come up with a useful answer soon.
