I just looked up a picture of the Cayman Design Edition 1, and yes, they appear to be the same wheels. They are the 19" turbo wheels. I had only seen them on a Cayman when I ordered them but I'm really happy I went with these. Not only do I like the way they look but I like the feel of them.
I'm sure I'll get my share of dents and dings. I'm already planning to actually cut the bush in my driveway that sticks out too far and I NEVER do any landscaping, so that's a first for me. Nor do I ever wash my car, but I think I might just have to start.
