Just picked up my 550 from its service. Took the opportunity to replace the original wheels with a set of 19" rims (from 575 options list). Also replaced the brakes with MovIt ones (http://www.movit.de/htm/380fr.htm). I found the original ones faded during a few track days this year and since I was replacing the discs anyway... Hope to get to Magny Cours in a week or two to try them out for real. Only allowed 1 pic per post: Rear.
