    remember, at your power level, it's not about weight or hp, it's about how fast you turn that shaft and it's critical speed.

    So acording to your theory, if someone goes from 3.23 gears, 26" tires 1:1 @ 6800rpm, to 5.33 gears and the same tires...everything else remain the same, he will be snapping the driveshaft ??????

    Or is just the longer DS as in AVEs, CC, EC tend do to more flexing at higher rpm?

    Have you made some stats of how many RCSB have this problem, compare to the others?

    One thing is certain, the faster u spin a driveshaft the more prone it is to breaking

    Gears tires overdrive all affect critical speed.

    Some break and some don't.
