RH RAL on Mich PS2s.
They're two piece, which is a good alternative to three piece, costwise. I'm very happy with them and the company that stands behind their product. I know that wheel choices are very subjective, but I've always liked the 3.6 Turbo Cup/Speedline look. These wheels have a very similar look. RH is now offering black centers with polished stainless lips for a same-cost alternative. Black centers w/polished lips look more aggressive on a black car, IMO (remiscent of the look of the black whaletail 911's with Fuchs).
I don't know what your budget is, but in your search for new wheels don't sacrifice tire quality and correct front offset for looks. I swear by the PS2s, BTW.
Here's a better shot of what they'd look like on your car; followed by how the blacks would likely look (photoshop) then a closeup:

Assuming that you use the correct aspect ratio (sidewall height) when moving up an inch or two in wheel diameter:
When it comes to clearing front/rear fenders or inner steering/suspension components, it's not the height of the wheel that makes a difference; it's the offset, the width of the wheel itself, the width of the tire, or a combination of all three. Those are the factors that you have to watch very carefully before putting non oem spec. wheels and tires on your car. As with most of us, if you don't have the luxury of doing a 'test fit', dont' rely on Tire Rack, or most of the aftermarket wheel suppliers for that matter, as they know less about what fits on our cars than many guys on this forum. Spend some time using the search function looking for those who have actually tried a specific combination - as there are many, many combinations that have been tried. Doing it this way will save you considerable grief.
So in my case, you have a tried and true combination of all factors that you know will work on your car.
My RH's are 18s with close to oem offsets. No fender rolling or spacers needed whatsoever. I could have easily gone with a 10mm wider rear tire, but I wanted to try to keep the front-to-back width proportion as close to stock as possible. A front tire with the correct aspect and a width proportionate to the rear wasn't available.
IMO, the only benefit to 18"s or 19"s for that matter on a street car is aesthetics. Going up an inch to 17" makes a pretty noticeable aesthetic look IMO. Going up 2 makes for a more contemporary look....but that's my opinion.
There are two disadvantages with going with a larger wheel: more susceptible to damage/bending; and cost (tires). The jury's out on whether ride quality suffers that much, but physics says that it has to, given that there's less air cushioning between you and the road.
It's very tempting to jump when you see a nice deal on a wheel set that came off of a Porsche other than a 928. In most cases, they are wheels engineered for rear or mid engined cars - not an up-front V8. After you've decided the wheel size that you want, shop for your wheels with getting the front offsets as close to stock as possible as a priority. Unfortunately this will rule out a good number of Porsche factory take-offs, as many of those front offsets are 50 or 55mm. Not optimal for a 928.

I'd stick with the original D90s. Looks like a beautiful car, why spoil it? It's really hard to find wheels with the crucial ET65 front offset, and the ride will suffer.

PS: Great find!
