A question for anybody running a DW8 with short trailing arms. Are you running your right and left bars at the same angle or 1 higher than the other? Also do you have springs LR in front and RR behind?
What we have run into is driver says when he gets on the gas it feels like the RR is not doing anything? Anybody experience this.

That is what I had under my Dirt Works. I ran the left in the upper hole, the right in the middle. If you have the new plugs from Dirt Works, they only have three holes. LR in front and rr behind is the best set up for this type, in my opinion. You need to run about 40# to 60# of RIGHT REAR and make sure your ride heights are set correctly. The need for right rear, instead of left is that the car will have so much bite on the left rear that the car will push so bad on exit and be extremely loose on entry. I had my car with 35# of left at first with this and couldn't control it on entry and exit. I talked with Andy Claiborne and he said to start moving to right rear. Make gradual changes, such as, got to about 15# of right, then after you get used to that, go to approx. 25#, then keep going up until you get the car to where you want it. Also, I took the short panhard bar off and went back to a j-bar with this. The shorty bar was WAY to erratic and carried the left front about 1 to 2 feet in the air. It looks cool, but it is a handful to drive like that. The j-bar calmed the car down considerably.

when you say "driver says when he gets on the gas it feels like the RR is not doing anything?" Do you mean the car picks up a throttle push?


Might need more info on chassis setup.

BTW, something you might try is LR behind with 250# spring, RR infront with 175# spring with 40# LR

alot of guys around here are on this setup with a 3 link and can flat fly

When he says it doesnt feel like its doing anything, I think he meant that it just felt like all of a sudden it unloaded the RR and he lost side bite and then the loaded left rear made the car push. We have tried from 100LR to 30RR and he says the same thing. I have talked to a couple other guys who said the same thing.

I was thinking maybe as the car rolled over it flattened out the RR bar then as he got on the gas the rearend rotation would unload the RR spring, And most of the weight of the car would be transferred to the lleft bar and pullbar. I thought about raising the RR bar up 1 hole. I know it is opposite of what most do but I was thinking that even with the car rolled over it wiould still have some angle in it and on the gas would load the RR a little more. WE built our own plugs and they have 6 holes instead of 3 so we have all kinds of adjustment. Currentyl Lr bar is about 4degrees higher than RR.

Dw8 left 51.5, rear 58.8, 80#LR 200Lr 175RR 750LF 650RF

Have you checked to make sure the shock or slider isn't binding or bottoming out? I agree with an earlier reply, that if you swap the springs and put the right rear in front and left rear behind, that should cure the "no right rear" problem, but that will be just a cover up for what is really causing this to happen. Also, you might want to check to see if you have any right rear lead. Try about 1/4 to 3/8 of an inch leading the right rear. If you have the short panhard, I would either run straight up, or lead the left rear. Leading the right rear will make the car tighter on entry, if that is what the driver is missing. The way I sprung my Dirt Works is 650 lf, 750 rf, 200 lr, 150 rr. Your percentages seem close enough.

ok, i talked to driver and he says car is pretty good just tight in the middle when he gets on the gas. Thinking maybe taking a little LR out might help or maybe a little more stagger. He says it doesnt feel bad coming off just tight in the middle.
