I sheared the splined stub axle where the spline ends. Both left and right side axles had already twisted and the right one finally sheared on track (corner 5 at Texas World Speedway). I had already ordered new shafts from RCR and they should be here soon but why should the replacements behave any differently? I vaguely remember Fran mentioning that RCR has beefer stubs. Anybody have any experience with this issue? The car has a LS-3 with maybe 500HP and maybe 460+ torque at the flywheel.
