I am going to be swapping my comp track out at the end of this season for something softer, if anyone wants to buy let me know. What I want to run is a 3in pitch CE track, I saw that they don't offer it in a 155 only a 153 for the cat. Can I do something to mod my rails for a 153 or am I stuck with running a 2.86 pitch. Also when you guys run a 2.5in track to you roll down the chaincase for clearence? I noticed that it only leaves about .25in or slightly more of clearence if you leave it stock. I like it that the assault is more wheelie proned and didn't want to move it.
