Do a search from about a year ago. There was a German car magazine publication (posted on the web) that tested (at a road race track) identically optioned (to the extent possible) C4S, C4GTS and Turbo (not S). Specifically, they all had carbon brakes, sport suspension, etc. The GTS did have the center lock wheels (which are wider than the 5 bolt on the S). The same test driver tested all three. The GTS was 0.3 seconds per lap slower than the Turbo. The S was a full second slower than the GTS. While many publications have pointed out that the GTS sits between the S and the Turbo, many have also observed that the GTS is a lot closer to the Turbo than to the S. I may be biased as I love my C4GTS, but for just a $5K difference, I would not hesitate to get the GTS. Also, as others have said, RAS is really nice. Not only does it make the handling better, it also makes parallel parking, U-turns and general city driving much easier as the turning circle is absurdly small.
