Good to be back to the dirt forum, been away from a computer for awhile. I have an older chassis, it works well under most conditions at most tracks. Recently the 3/8 mile track I run at has decided to leave the track to get very hard slick. I am having problems with both, side bite and forward bite. The car, without braking is getting sideways as soon as I get off the gas, and very loose coming off. The reason I state it is an old car, is it has no adjustments for swing arms or rear bars, rear bars angled down to rearend and swing arms angled up towards rearend. Pull bar is at about 17* J-Bar slight angle downward toward rearend. Any suggestions??

just a suggestion, but if your track isnt too extremely bumpy a short straight panhard bar would help the side bite a bunch over the j bar. I have a short bar on my car and it seems to work really good on dry tracks.

If you cant do the short bar raise the left side (chassis side) of the J-bar up 1 inch at a time until you like it. Try to ballance your front tire weights to help the loose in condition, or turn in less front brake.

You might try a shorty bar as badfast recommended and/or add more rear weight.
Try some easy up front shocks. You could play around with putting some rearsteer in the car also by leading the RR.

By putting lead into the rr will this tighten the car up? I will have to borrow a shorty bar and try that sometime, but if I raise the J-Bar on the chassis 1-inch, what changes can I expect? The track is very smooth, never any holes.

Thanks all.

Raising the chasssis side of the Jbar will allow the car to roll over easier and help tighten the rear on exit. You can also try a different offset wheel on the left rear to tighten it up. You can also lower the J-bar on the pinion mount if you can. The more angle on the j-bar the mor the car gets up on it. We raise ours 2 inches for a dry slick track and it hikes up on the bar sooner. We tried the short bar on our mod and our LM and the track is rough enough it busted the mount on the LM and ripped the mounting bar out of the mod. The better term would be pushed it out.

Thanks Ego, I am going to try raising the J-Bar 1-inch to start, I usually run a 3" offset wheel on the LR, last week, I was going to put a 2" on but it would have put too much stagger into the car. Thanks for your help.
