    That's a bit of spring split isn't it

    Eric it works really well for large flat tracks. Not so much for our bull rings up here in the northeast.

    Just looking at this thread again. I went to bump n run down in nc during vacation. I used this setup exactly and it worked great. TQ and a mixup in the main in 13.5 spec. No slouches running there either. I would start with this as a solid baseline and play with small shim adjustments first.

    It my home track the carpet is super sticky. We run cot 17.5 because it's only 87 ft bullring. What to do to get the car out of the carpet. I have good rip up front and then 4 min in it feels stuck to the track and gets slow. We run 5 min. Setup is very close to what is posted above. Thanks

    I recently raced at a track that has a ton of grip, it's sticky. I race 17.5 spec truck. I have been using the set-up that is posted above as well at my home track but because of the high grip at this other track I went up on the front spring rates, up on center shock spring, up on center shock oil, and down on side shock oil. Also went down on tire diameter. It all seemed to help, and it was fast. I hope this helps, I feel it was all in the right direction.

    Ok thanks. I will try that this weekend. I know the ksg guys are really soft in the center spring. 5-6lb on a vplate setup. I'm also running purple progressive front springs. I thought about trying a hd2500 tplate and stiffer side shock springs

    Since you are running Spec tires, there's not much you can do. Here are a few tips to reduce tire grip:

    • Smaller diameter
    • Less front contact patch by increasing RF caster and/or camber.
    • Less rear contact patch by camber cutting rear tires, or step cutting.
    • Less tire sauce and/or less sit time.
    • Muddslide tire sauce or high SPF sun tan lotion
    • Clean the tires with motor spray or lighter fluid between rounds.
    • Clean the tires at the end of the night.


    To keep tires the hardest, it's important to clean the tires after the final run of the night. This is the only way to stop the tire sauce from continuing to soften all week long. To see this point in action, take a tire off after a race and throw it in a drawer. Check it out 6-8 months later and the foam will be super soft and peel off the rim as if there was little to no glue on it. I've found the tire sauce continues to eat at the rubber and glue for about a year. Another way to prove this point is to start a tire large (at 2.18 or something) and race it for a month down to 2.08. Then take a brand new tire, true it down to 2.08. Even though they are both 2.08, feeling the difference is night and day.

    Here are some more setup ideas to reduce grip:

    • Stiffer T-plate
    • Stiffer center shock spring/oil
    • Stiffer front springs
    • Move the motor rearward with smaller gears
    • Move the right wheels to the right
    • More Ackerman
    • Less spoiler
    • Raise front and/or rear roll center
    • Reduce body rake

    This should get you started. RF 1.055", RR .735", LR .430", LF 1.035". All measured from the top of the aluminum mount to the highest point of the post, keep in mind you will need to chamfer the post for clearance and angles on the body.

    Thanks for the reply. Do you happen to have the overall lengths? I have the GFRP post holders in the front and the Mcpappy ones in the rear. Thank you
