Please help identify these wheels

Hi everybody...coming back from lunch today I noticed an awesome looking GT in our parking lot so I had to take a closer look. Can anybody help identify these wheels? I couldn't find any distinguishing writing and I didn't want to linger too long. They are very similar to the FR500 replicas but different because the lug location is in a different place (looks more aggressive to me) and they have the little rivets all around. These are 20-inch wheels with 275's in back and 255's in front. I already had my eye on the FR500 replicas but I really like these as well. I have a feeling these are expensive racing wheels though. I didn't recognize the center cap either (it's shaped like an "S" but it's not the Steeda logo); could be a generic cap I suppose.

I apologize for the picture quality (camera phone).

Thanks!

Thanks, Sam, these are indeed Stern Beasts! Looks like a very nice wheel but more than I want to spend right now.

okay scratch that, the first site I found wanted ~$600 each but on your suggestion I searched ebay and found them for ~$1000/4!! Maybe within the budget afterall!!
