I was in a pickle late last year and wrecked my 159" track and found a new 163" for a good price and through it on but as you might know it when I went to tighten it up it was just to loose so tore it back out, took a few measurements and slid the skid back about an inch. Now for this year was wondering if i should just leave it or actully buy a set of 163 rails. I gues my real question is how does this actully affect the handling of the sled? When I rode it lase year seemed fine but that was just for one ride.
