I've read that you can't fit the 16" wide tracks in our tunnels but i'm curious if anyone has trimmed a track or ran another brand track instead. Ideally Id like to to go with the 2.5" flex edge track 146-154 long. Has anyone done this, what did you run into? Since skidoo won't offer a new 600 summit with any good stuff shocks/bracing like every other manufacture I'll just stretch the old racer and stick to the mod classes. I would like to buy a new sled and run the stock hillclimb classes but the stock summit sp package suspenders suck sooo bad for it..
