1296 lr 1296 rr

Jbar 9.5" on chassis side 2nd hole from bottom of pinion mount

Lr trailing arm in 3rd hole up about 10degs angle.

140# lr 59 % rear weight

went from running an extremely dry slick track to a very rough track!!! Need help

Thanks

my dad says thta split valve shocks make the car terrible when the tracks rough, so i always take the split valves off when im on a rough track, and maybe running softer rear shocks would help a little too.

What we did,at the advice of our chassis builder,(DirtWorks), was to take angle out of our bars. We dropped our trailing arms 1 hole, & lowered our j-bar 1 " on the chassis side. That seemed to help alot, & didn't really hurt our car at all as far as cornering or forward bite. We also took off our splitvalve shocks. Hope this helps.

im new to all this car lingo...im assuming the the split valves are the front shocks.

Car is bottoming out all the way around, each shock is bottoming out. Thanks

yes the fronts are the splits. Take them off when it gets rough. Run a 76 shock up front. The rear shocks look good for a rough track. Take some angle out of the bars like trasrat89 said. If that doesn't get the desired result you may need to stiffen the rear springs a little. Like 25lbs per side.

im kinda confused i guess, are stiffer shocks better on a bumpy track or are softer shocks better, i always thought softer would be better.

Think about it, the shock numbers designate the compression and rebound forces of the shock. On a smooooth track you can use shocks with small numbers because the shock doesn't have to work as hard to keep the tire adhered to the track. When it's rough the shock has to work much harder and therefore you need more compression and rebound. Use straight valved shocks until you get your car working well and you understand what the split valve shocks do.

take angle out of all the bars, raise the car up about 1 inch in ride hieght all the way around, flatten out the j bar. take off the split vavle shocks fi you can. step up your rr spring for cms, you need a stiff one and drive with the car very loose on exit.
the raising of the car is to clear ruts, last year we had to raise the cars to keep oil pans on them.
