Well My first race day I had mine slipping a little but it didnt seem overly excessive...at least until i tried pulling the spur off and discovered the spur melted and fused the outer hub to the shaft. It also discolored the slipper spring at its base so now its blue lol.

I remember seeing temps on the outer pad as high as 170.

I am now running the dual pad basket and hot racing vented slipper hubs, and high torque pads. Have it slipping pretty well and its cool to the touch. haven't put an actual race on it so will report back later.
