My sub frame is now bent on both side which has rotated my spindles to a more vertical position. I'm running Pilots with 4.5 shaper wear bars in the center and no studs on a RTX. I've discovered that with the spindle relocation my wear bars tend to dig and catch causing the rear of the sled to constantly kick out. I believe the spindles and ski rubber stoppers transfered most of the pressure to the front of the ski pushing the tips down. It's almost like the front of the ski was shimmed rather than the rear.

I pried the spindles back close to their original angle and the skis are handling much better again.
