Received them today!
They're very good quality wheels, the finish is beautiful and the casting and machining is top notch. No complaints there. These have OER cast into the back:
As for being reproductions, they kinda fail there. The gold is MUCH too light compared to the originals.:
The texture of the painted surface is much more coarse on the originals, and finer on the reproductions:
The spokes don't have nearly as much depth, either:
At first I thought that might be a difference between 15x7 and 15x8 wheels, but photos of WS6 cars on the Internet seem to confirm that the spokes on these reproductions are a fair bit less deep. This means there's less gold-painted surface. It probably helps with weight a fair bit, and possibly with caliper fitment.
The 15x7 wheels seem to have a dish in the middle, whereas the 15x8 wheels don't, but I'm pretty sure that's true of the originals and not a quirk of these reproductions.
Considering what I paid for these ($695 shipped through Summit), I'm really happy. I wish the gold paint was a better match, but other than that they should look great on my car.
