I have the oversized wheels and drilled the sliders along with the suspension settings. My slider wore to the rail at the bend, melted the end cap right off, peeled off the slider, wore the rail and speared the track last spring. Just prior to that I was going over 180kms.
I replaced the skid with an RX, Viper shocks, advantage Ohlin extensions at the front, new 9818 track and I ordered SLP anti hyfax wear pads from Sudbury Cycle. I can only wait and see if the wear pads work. I am still running the oversized wheels.
