Hi This morning I nipped down to CC (main reason was to take back a flawed diamond cut Apollo wheel ) and had a good look at several cars running ZZR (same profile as ZZS) and a chat with eternally helpful Dominic. We had a look at wingstays together, including my own, and established I am not going to have a problem. Also, I had a chance to look at both ZZS and CR500 fronts. Conclusion, the ZZS are slightly heavier. But they look so good like you say, so will get a set when they are available J
