The overwhelming bulk of the changes in the car from track to track are setup changes. These are designs they put an enormous amount of work into over the off-season, and a significant amount of test time, so it seems circumspect that they would radically if even marginally change them mid-season, before even considering the incredible tight restrictions of F1 (which are there for safety and fairness, but also to try to keep it within "reasonable" fiscal bounds). Teams come out with a season design, and from that they adjust wings, tire pressure, gear ratios or change points, etc, within the tolerances allowed. I've only marginally been following F1 for the past year, but I'm wholly unaware of any substantial construction change from track to track. Edit: To substantiate this a bit, here's the Ferrari car at Hockenheim (a very high speed track), compared to Monaco (a twisty, "urban" track). http://www.zimbio.com/pictures/bGZpJEcephz/F1+Grand+Prix+of+Germany/Y2745loz6A8/Kimi+Raikkonen http://www.zimbio.com/pictures/bGZpJEcephz/F1+Grand+Prix+of+... http://www.formula1.com/news/headlines/2014/5/15851.html http://www.formula1.com/news/headlines/2014/5/15851.html (click on the Ferrari picture)
