calm it down

On the front end try lubeing the king pins with sure lube. That will help with the bounce bounce. Try a softer t-plate, .063 slotted if it works on your chassis. Make sure you have some rear droop on the pod. so that you have movement forward and back.
I have also had good results with running the rear of the car in the long configuration. this gets the pod spaced further from the chassis seems to really help with a bumpy track.
Make sure you have enough chassis clearence. If you are bottoming out or hitting the track on the rebound of a bump, that will make it lose alot of speed and unsettle it too.
What type of surface ? Chassis??

And of course softer springs

On a Bumpy track generally going to softer oil in the center or a bigger hole piston combined with softer springs helps the car over the bumps. If you have too thick of oil or too small of a piston when the car hits the bump your trying to push that thick oil through too small of a space and the back end will "jump" versus absorbing the bump and going over it.(kinda a bottle neck effect) Be careful with how much preload you have on your center spring also, too much preload isnt good for bumpy tracks.

At Halo Hobbies for the 05 carpet nats (Halo was pretty bumpy) I ran an AE shock with 40wt and #2, and it was a huge difference from 60wt and a #3. It was some advice from TJ Domark and it worked! This is all with a fiberglass .063" t-plate, it might be different with a spring steel. Moving your center shock higher on the mount helps with the bumps too. Thicker dampening on the front kingpins can make a big differnce also. Depending if the car is bouncing the front or the back.

There is sometimes a comprimise between a car that is easy to drive and is smooth and a car that is fast. Sometimes you just have to wheel it! LOL :thumbsup:

Extended rear pod plates helped our L-4 drasically .

Either made your swingarm effect less sensistive or a longer wheelbase car flowed over the bumps better ??

We tryed it and it happened to work.

North Haverhill requires a softer overall setup than alot of other tracks and probably a little higher ride height.

Long kingpins also.
