I don't know if this will help you but I uploaded one here: http://www.xpgamesaves.com/files/file/2833-cars-2-disneypixar/ save is at 840GS 45/50 but. Yes there is a but: I tested it on my test profile and got nothing. I could not even get any achievements to pop by doing them legit while using this save. I only put about 10 minutes into testing it and tried testing the nitro,jumping and stunts, the disruptor challenges and a few of the object smashing achievements and could not get any of those, I did not actually complete any races. good luck.
