Too much IMO, It's also too long to fit the rules if you plan on running in any comps. You might want to check the USRCCA rules in the competition section. | |

| Good luck getting an X-crawler to fit any rules for any class except for super class. Whatever you do.... use really really big tires!!!! |

I sure wasn't suggesting he try and run it in the 2.2 class. 20" is too big for the Super Class rules though. And Cory, just cause Tom tom says big tires, don't go for the stupid Jumbo Kongs. 40 series Moab XL's will suit it just fine. | |

my guess is that because it's a torsion chassis, when you shorten the wheelbase to 16-18" you'll also reduce the amount of flex. try it and see |

I run a longer truck last year but for the new rules I shortened up to 17.5 and love it.I would go in the 17-18 inch wheelbase range. Now on to the articulation. If its a Pimp Cane style chassis when you shorten it it will get stiffer.And if that's not enough I know on my clod pimp cane that I run year before last I made a bracket that attached further towards the center of the chassis to make it stiffer.The braces were also A good tuning aid.You could make the front or rear longer than the other to change how stiff it was front to back to make up for weight differences ETC. |

x2...i run 18 inches...you run a piece on the top of the back bone. the longer it is the less articulation because you have boxed in or squared a piece of the chassis. I used to run mine with about 110 degrees, and never had a problem with it, so just try it out stock and see what it does. tires...you want 40 series or axial oversized. | |
