When shimming these skis, so it reduces darting. Is it hard to put the skis back on after, because I know on my DOO the saddle/rubber piece fits perfect, so I'm not sure how you can add a 1/4" shim and try to put the ski back on? Is this going to be a painfull experience trying to put the skis back on with the shim attached to the rubber saddle.
 

no, its not too hard at all. i used a piece of belt and screwed it into the back of the block. line up the tabs with the spindle and lift the front of ski and it will go.

Do you have any pictures of this done or in the process of being done?
There's a whole "How To" with pictures in the tech section.

Just let the sleds weight compress the rubber saddle and line up the hole. It's definately a tighter fit with the shim installed - but it works great.
 
Shim the skis

For those of you shimming the skis, have you ridden the sleds first to see if there is a problem, or is it best to do it before riding?
 
I drove mine and it darts a bit and that was on a raod, so I can just imagine on a trail.
 
To shim or not before I even ride teh sled?

I looked at the wear bars on my Apex as it is sitting on the garage floor currently. There is only a section of the wear bar at the rear, about 3 inches that is off the ground, the rest is sitting right on the ground(these are the original bars, will be changing to some Woody's 6").

My question is, would I be better to wait until I mount the Woody's bars and/or ride the sled before I experiment with the shims?
