I just gotta say, IMHO, if you have a Shadow Mica and are looking for something that looks somewhat "factory" without all the bling, you can do no better than the Konig Rewinds in graphite. (Of course, that's because that's what I have. )
The pics don't do 'em justice:

 

I like the "Rewinds". If I put aftermarket wheels on those will be the ones. I brought home my Shadow Mica xB last April. I am doing a few things with the suspension in the near future.

To appreciate the Shadow Mica color you need to be in the sunlight.


What was the size Rewind you insatlled on your xB?

 

OldT,
I bought the 15" (stock size) set from JLB Motorsports (http://www.jlbmotorsports.com/rims/konig-list.html ) at around $95 bucks a piece or so, w/free shipping. When I took 'em to the local tire place to have the stock tires mounted, they ask me if there were any hub adapters as the center hole was "slightly" wider than the xB hub. I said that JBL didn't mention any. So I called JBL and they ask me if I was getting any vibration on the highway. Itold them that I hadn't driven it on the highway enough yet to notice anything, but if there was a chance of vibration, how much were the adapters? "Three bucks plus $5 shipping." I told thm to send them out and my tire people installed them for nothing when I took the car back to recheck the lugs.
Overall though I was pleased with JBL... I don't know if you can find the Rewinds any cheaper anywhere else or not.

I also got the chrome Gorilla lugs for the xB studs when I bought the wheels.
