I too am a novice at this sort of thing. I decided this year to get a seperate set of wheels (16x7 and 16x8) for dedicated track tires and have a heck of a time finding the 8s. Am working with Paul at Radial Tire and while it may take some time, am confident he/we will find something for less than the $$$ that folks seem to think 8s are worth.

Offset works with spacers and longer studs. Tyre width and size might be problematic. Some already use 17s and 18s but width in front is critical on narrow bodied 911s. Course you might be able to play with spacer width to get clearence on either side.

Hey guys, check out http://www.wheelenhancement.com Those guys have a huge selection of OEM and aftermarket wheels and are very knowledgeable -- they will be able to tell you which wheels will fit and what spacers you need to use if necessary.

Spacers are bad...it's MUCH better to get wheels of the correct offset and backspacing -- in other words, wheels that fit.

Noah’s right some spacers are very bad i.e. the ones that bolt to the hub and then have short studs to mount the wheels to the spacers. Porsche used spacers on 911 Turbos, 924 Turbos and early 944s (rear). I thought they used them on the front of the 911 Turbos too. It does take longer studs, which are available from Porsche.
I wouldn’t use the spacers with the intregal bolts but I’m already using the Porsche OEM ones on the 931 and early 944 track cars

Here's my 85. Very slight rub if at full lock, seems to work pretty well otherwise.

[edit: I'm not sure how it would work on a track though if that's what you wanted the bigger wheels for.]

Spacers also create more leverage on the suspension, effectively softening it. That increased leverage will also burn out wheel bearings more quickly.

I have 1/4" spacers on the back of my car and 3mm spacers on the front, but it's for brake caliper and oil line clearance. Small spacers are pretty harmless. It's the big ones people use to space out grossly unsuitable rims that are problematic.

With the introduction of the 964 and its larger brake calipers and coilover suspension, the offsets of Porsche rims changed dramatically. That's why you have to use massive spacers to fit late-model rims on torsion bar 911's.

(I'm also one of those curmudgeonly types who thinks that putting modern-styled rims on an old car just doesn't work, visually speaking.)

I keep going back and forth on if I like the new or the old look. These wheels were on the car when I bought it. I picked up a set of fuchs two months ago which I planned on switching it back to this spring.

The side view of your cab looks almost like a 993 with those wheels.
