I got a set of 17's a while ago (while the dollar was pretty strong). They are a very high quality wheel and the adapters look quite sturdy.
Bob Lacey was very good to deal with and packed them quite well for the journey too.
I'm very happy with them, of course I'll be happier when I get some rubber and they start turning.
I would be careful with the measurements listed on the website though. My wheels had more front spacing than I was expecting, so I had to narrow the rear-end to fit them (which will help with my "other" wheels anyway). I can provide you with any measurements that you may require.
I only took one picture and this is it.
