    dirt works set up?

    I'm looking to help a guy with a 07 dw with the short rear bars 12'' and 14'' 4 bars both sides with the lr on a coil over behind. what's a good to start we're changing springs and possible shock's the car has a aluminum headed 392 sbc and a qc rearend if that helps. the car now is tight and wants to carry the lf. we have spaced the rr out lowered the j-bar on the frame also the air pressure on the rf seems we had to run it low to get the car to turn in the middle. has the basic dw set up as far as springs and shocks.

    add leftside weight what wheels are you running now. I ran a dw years ago that also had 14 upper and 12 lowers I had to run 4 in wheels on leftside and add leftside weight that car had around 50.5 to 51 without driver ran 3in wheels on right side

      That is what we done years ago you may run 3in wheels on left and 2in wheels on the right and run a 2in even on the lf . I had the same deal always packed the lf I also shorten the wheelbase a 1/4 on the left and lengthen on the right. If my memory is right the dw had no left side weight and a lot of rear % so we added left to loosen on entry .I would also watch lr drop you may getting to much with the short bars back in 2003 we did not know much about the springbehind.

        low air pressure in the RF seems to point to needing a softer RF spring. Not sure what "standard" is but i would soften it 50-100 pounds. This will help keep it off the RR and help it turn in the center/exit as well.

          we set everything off the DW set sheet that is on the dirt forum other than running the spring and shock behind on the lr.


          Sorry for the delay my computer has been on and off due some kind of issue.

            So like 700-750? if so i would soften the whole frontend and get like 550lf 600/550 rf or something close to that.

            Measure the drop on the LR should be between 4-5inches difference from r/h to full drop measuring where the birdcage is. If its closer to 5 shorten it up to 4. If you have two sets of holes on the LRU birdcage run the back set.

            I would try drop and front springs first then see where you are at.

              the set up sheet we found was 650fl,750rf,225lr,175rr wheel offset are 4 inch on the lf and rr, 3 inch on the rf and lr the shocks are the integra dry slick set up. WE RAN 14# in the rf I've noticed a lot of the faster cars are running higher air pressure in the rf tire

                  That setup sheet is from the early 2000's. Do like Matt said, 550lf, 600rf, 200lr, 175rr.

                  Do you have the corrected uppers or stock mount location?

                  Do you have the early 64-67 chevelle or later 68-72?

                    I went back and re-read his original post and i think alot of his problem is likely the LR on a coilover behind. He has nothing to keep it from jumping up on the bars. Seperate the LR shock/spring and get a slider for the spring behind, put the shock in front on the birdcage, i would assume the shock you have now is a 6-2 to 8-2.

                      yes a 6-2 lr I was thinking of going to the spring behind shock in front that's what I ran on my predator mod just not many DW's in my area to share info with.

                      front clip is 64-67

                      pm's are clear

                        Get the springs jimmy and i suggested and seperate that LR shock/spring, raise the Jbar back up on the frame and see how it goes.

                        I should of probably asked this sooner but what tires are you on?

                        I'm not sure what jimmy was getting at on the clip maybe he will chime back in on that one.

                          If its hoosier UMP a straight bar to the outside of 2x2 bracket may be just what you need.

                              I also have a DW11, but I run on the IMCA hoosier tires with steel heads. Would this same info apply? I have the 650-700 springs front, 200-175 rear, and the LR on a 8/2 shock. Haven't run it yet, but looking to get it set up out of the gate then adjust from there. Any help is appreciated.
