Thoughts on these wheels?
Only found a couple 928's which have these wheels via search and only 2-3 with photos...
Sport Classic II Wheels for Porsche® 928
http://www.928motorsports.com/parts/...sic_wheels.php
I emailed and they said "No spacers should be required, we try to get the offset right the first time. "

Quote from the link, "Sold as a set of 4 including 18x8 ET50 fronts and 18x10 ET85 rears plus 4 aftermarket center caps."
IMO those ET's suck for a stock-bodied 928. ET85 in the rear? If that's not a typo, those would probably fit in the front pretty well with a spacer.

One of my all-time favorite 928's has the sport classic 2's on it. Gorgeous. I had them on my Boxster for a while.. You'll spend a lot of time cleaning them but they're beautiful wheels.

Would any of these be the same fitment?

Ah, that's not my 928, sorry to be misleading. 2 separate people and cars. The 928 pictured above is a RL member though, perhaps he'll contribute. I'm not sure what proper offsets etc would be. Far more knowledgeable people should chime in to help.

Do a search for wheel offset and you will find lots of discussions about this subject. In the front, an 8" wheel with 50mm offset is pretty much the absolute minimum offset, and too small for me personally. A spacer will only hurt the situation. In the rear, it's much easier; an offset 45 - 65mm will work. If it's in the 60's or higher, you can always use a spacer to correct.

Those are some beautiful wheels ... the offset (or ET) in front is important to steering and handling, not just visually filling out the wheel arches. The stock 7.5" front wheel was ET65, which was a unique size among all Porsche models. ET is the distance from the centerline of the wheel to the point where the wheel meets the hub, so the additional 15 mm vs. the more common Porsche 7.5" sizes means more of the wheel/tire lies inside of the hub. Not sure the exact reason they did this, perhaps for straighter tracking and high-speed stability?

It would seem then, if I understand this correctly now, the ones I posted from ebay at ( http://cgi.ebay.com/ebaymotors/PORSC...item1e61a74418 ) which are
Front
18 x 7.5 with 50 offset
Rear
18 x 10 with 65 offset
would fit fine with a 15 mm spacer on front? Or do I have it backwards.. Sorry, I get spreadsheets, and pretty much most logical matters (believe it or not I majored in economics so would think I would grasp this!) but for some reason cannot wrap my brain around wheel fitments!

Keep an eye out on Craigslist for these also. I saw a set a couple of weeks ago local that he wanted $750 with good tires. Also call the local dealerships, they might have some take off's for cheap.
These can be had fairly cheap if you shop around a bit.

Keep in mind that the wider the wheel, the more offset you need to stay in the stock range. 7" ET65 is the stock 928 wheel. A 7.5" ET50 wheel will not stick out as far as an 8" ET50 wheel.
