no rubbing either. I can slide 2 credit cards stacked on top of each other between the tire and the lip... only until the raised numbers.... the way the 928 suspension works as the wheels move up into the body area they move inward and away from the lip. When I jack the car up and the tires are about 2 inches off the ground they do rub the lower control arm on the front. I have never seen rub marks on the arms so I must not be doing any dukes of hazard jumps.
Front's are 18x9 and I don't know what offset Fikse uses. I'm running 265/35/18 on the front. I'm actually having issues getting tires in the sizes I have now so I have a delima

To get a 265 in up front you will doubtless find your wheels have an offset of ET68mm there or thereabouts unless you did surgery on the front fenders. I suspect they would also have fouled on the roll bar at full lock unless you fitted an extra spacer on each side of the steering rack as I did.
To get that rear rubber in the wheels probably have an offset of ET40 mm assuming no spacer or ET60 with a 20mm spacer- does that sound about right?
I had another set of Fikse wheels prior to these and were 17x9 and 17x10. When I was having the GTS quarters installed, I purchased a 2 inch spacer and bolted up what I had. I cut the bottom of a shock off, so that I could bolt everything together and articulate the suspension up and down. Everything cleared, so with that information Fikse then made a set of wheels. It wasn't easy at the time and Jim Fikse himself was a chore to deal with. I offered to pay up front for the set, and it still took 3 months to get him to agree to make the wheels.
335 x 11 x 18
8" offset - don't know the offset in mm's.
8 inch is not offset- it will be the back spacing value and amounts to an offset of 65mm if my mental arithmetic is correct- a sensible number for our cars.

I think you have a picture with those 17’s on my car, next to yours with the 18’s and then that stock picture you posted. Those wheels looked great.

I haven’t tried mine with tires but I have developed two options on the front, one was made with two piece Porsche wheels, they are 9” with 69 mm offset. The rears are 10” with 65 mm and custom hubs and no spacers. The other is 10” at the front with 82.4 mm offset and I will put another rack stop on each side with those, on the rear 11” 51 mm offset similar I think to what others have on here, might run a 315 or 305? I suppose it may depend on what tires are available.

The 69mm offset front wheel is perfect and although a bit on the narrow size, can still carry a 265 section and that is excellent for most uses and even then I expect you may need an additional stop each side of the rack.
The 82.4 front offset may work for track use but for street use I suspect it may be somewhat problematic lock wise I would politely suggest. Use of the Devek bar [as I do] also limits matters a bit so your roll bar setup may well control whether it will work to your satisfaction [or not].
18x10 ET82.4 is a full 45-50 mm further inboard than any of the common stock front wheel fitments. Even the spec'd 928GT Cup front wheel (9.5x17 ET68) sat 21 mm further outboard. 82.4 seems a bit radical, and I mean that in the Jim Gaffigan sense of the word.
