I saw in a picture post that some people were interested in this 15x6 OEM style wheel, but don't know where to get them. When I was deciding to upsize my wheels I came across the following site. They are a Wheel Refinishing company in the USA.
Go to the following web-site:
http://www.aaarims.com/cgi-bin/Web_store/web_store.cgi
It asks you to enter a Product ID #. Enter 692131F and Press "Submit Search".
The company is in Holland, MI.
The wheels definitely are flatter in profile than the 14x7 on the P type. I would imagine that a 1/2" spacer would space the wheel out better, but then you've got the issues of longer wheel studs and hub-centric centering of the wheel.
They list for US$155 per wheel less centre caps.
Worth a look for those who like the OEM look but want slightly larger diameter tires.
