Thanks for that, 3.2.5 Differentials states that diff ratio's are free. Is this correct, can you change your diff gears? Did you run in the touring class and if do how did you find it, I am thinking of setting up my SWB Mav to run in this class next year, will they have a touring class in the Alpine Challenge?
