Damn the RS box is cheap! Anyone know if the only difference between the RS box and the regular MTX75 is the diff, or if it's toughened up some more... I saw on some getrag page that the MTX75 was specced up to 345Nm ... the iB5 for something like 170Nm ... just curious if these were very conservative specs or not.. because I have a feeling a lot of people will be pushing their RS's past the 345Nm mark
