What clutch bell are you running? I'm thinking about a 14. I race this truck on a dirt short course... its not a super fast track... I'm looking for some more down low power but too much where it slows the truck down in a big way.
" Some times you gotta race it out man" -Me
Try working it down go with 15 see what u think Then try 14?? Or you could change up your spur to a 38??
