O you can have a lot of fun with that setup. But if your sled is making any kind of power you will stretch the track from hard launches on ice, than the outer picks will grind out your heat exchanger before the centre ones do.Even with shimmed protectors there will be a time you have let the track go loose.
Now take it up too the c note and let off the gas. The under side of your tunnel under the seat will look like freddy kruger was under there. Just push up on the track with your hand and see if the picks hit under there. Yes you can put bigger protectors or shim them as well but use lots of good rivets because they will come loose.
Now take a jump and land the wrong way on the *** end and ,,,you guessed it.
