what do you guys do to your cars when the track gets rough? mines a 4-z setup and the thing flies when it's smooth, but when the track gets rough (as it has late in the season) it's a handful (it'll hook up too hard when hittin some ruts and upset the car really bad, kinda shoots off toward the wall, then ya gotta gather it back up and try to keep goin which isn't a very fast way around the track). I was thinkin i should have taken some panhard angle out but we'll have to wait till next time to see if that woulda done the trick. any ideas are welcome

Got on the track the other night and it was a lot rougher than it looked. The car was fast but all over the place....eventually had to get out of the gas...hate it when that happens. Went to the pits and took some angle out of the top left bar on the four link (4/zlink car) and it settled the car down a bunch. 4 bar cars seem to get upset on rough much little control!

I agree, tame the left bar down and drive through the ruts using alot of throttle. You could always use the old faithful idea, when in doubt hold it to the floor. Ha Ha I run a 4bar and do not have good luck on rough tracks also, found if I take alot of bar angle out of it and keep it from lifting alot it is a ton better. It is still not like driving a two link through them.

Our promoter resurfaced the track during the season and it got very rough. The 4-bar cars wen't straight to the back or just pulled off. The 2 links and leaf cars finally had their day. I don't know what you would do to the bar cars.

I run a 4-bar also and at the begining of the year the track was a little rough. I had the same problems the rest of you guys do. I have a few suggestions.......first off dropping the LR bars down will help. You could also stiffen the rear shocks a number or two. If all else fails do what I did. I bought my parts but you can make them yourself, however you like. I put birdcage lockout brackets on mine and when the track gets rough I lock out the cage and take the upper bars off. PRESTO!!! 3 bar!!! It worked for me. Hope that helps. I got my lock out brackets from A-1 racing. Thats the type of birdcages I have also. They were $20 each. I think their website is

interesting idea with the lockout birdcages. i've never seen that up close that i know of, but if it's like you say, then no 4 bar car should be without em. and i don't run much angle in my bars so that shouldn't be hurting me. as for the leave it on the floor theory,the handling was just too erratic, i wish i could have just stuck it to the floor and hung on, but my car would break loose in the rear real easy at the same time it was tight in the rough, so i think i would have looped it with that strategy but thanks for the ideas guys. hopefully the track is smooth for me next time, cause that is when i like stickin it to the floor and goin real fast and real smooth.

Along with working with the four bar angles you should also be concerned with the shorty panhard bar if you are running one.These should be removed and a j-bar or long panhard bar with no more than a 3 in. drop should be run.This will keep the car more driveable when it is rough.The shorty will cause erratic handling on rough surfaces as it creates the same quick loading and unloading of the left rear(pogo sticking).

if your stuck on a short bar, some people dont have a j bar. then go top hole on pinoin and like 1 inch rake. that will free up the car and take out alot of the hike up.
