So when you install that shim under the rubber is it slid to the back part or the front part of the rubber?
I have an opportunity to do that right now, and my darting is ridiculous. Local shop is telling me to set the mono shock to as soft as possible, control rod set to max, and toe-in 1/4" and ride it, if it's still a problem, lengthen the limiter strap.
I get confused listening to some of the advice on here which seems to contradict what he is telling me. I mentioned that to him and he said that the riding is way different in Alaska compared to L48. I'm not the most experienced rider, but if this doesn't help. I will go with new skis, which brings to about $1600 of additions to make the sled what I want. (144x2 almost done) Dealer did mention that the new Nytro MTX skid has a more adjustments with the added limiter strap in the rear - he said that way you can shorten the rear strap, lengthen the front strap and decrease the approach angle - is it possible to add a limiter strap to the rear of the attak skid?
Toe in??? Never toe in..that just makes crappy handling and darting worse. Shim the back for less darting, but harder steering. Shimming the back gives the skis self centering.
I used friction tape on my rubber inserts to keep them in place. Worked for hundreds of miles...need to check to make sure they stay in.

I cut out tractor tire tube rubber, trimmed a little half circle so I could stick them into the gap farther, and stacked them if needed. Some contact cement will hold them if needed.adirondac blue said:Does any body have a pic of the shim and exactly were to place. I tried simmons skies and not impressed at all.

THE SHIMS WORK GREAT FOR A WHILE UNTIL THE STOCK SKI BUMPER RIPS AND THE SHIM SINKS INTO THE RUBBER. WE NEED TO FABRICATE SOME TAPERED WEDGES THAT ARE THE SAME WIDTH AS THE STOCK BUMBER AND TAPER BACK TO ABOUT 1/4 INCH. THIS MIGHT ELIMINATE THE CRUCHING OF THE STOCK BUMPER. I AM ON MY THIRD SET OF STOCK BUMPERS. ADMITTEDLY THE SHIM TRICK ELIMINATES THE DARTING FOR MOST OF THE SEASON. JUST COUNT ON REPLACING THE RUBBER EVERY YEAR.
