    Keeping LF down with lead placement???

    Would a 22lb piece of lead help keep LF from coming up? Where to place it if so?

    How high is the left front coming up? Lead would help but that is just a band-aid fix. and as far left and forward as possible will make the most difference, but i wouldnt want to put lead on the front of the car.

      6-8 inches. Every time I bring it down with LR drop, bite, jbar, and 4bars. Car seems to slow up. That's why I was asking about lead!

        lead should NEVER be used to fix a problem like that. i wouldnt even call that a bandaid fix.

          Have you tried running less fuel and how much lr drop are you taking out?

            Taken out anywhere from 1/4 to 1 1/2 on drop. It seems to be best around 45* max travel. 150 bite, 4 bar standard, jbar 7 1/2 split

              why not just take some bite out.....that much bite could be why its lifting the lf.....most are between 30 and negative 30 on wedge

                I've seen several cars run with the lead up there, guess it was for lf lifting, never asked. Thats a lot of jbar angle but if it works. At what drop did the lf quit lifting and is that lr bite with driver? Have you tried moving the pull bar to the right if you have that provision?

                    lead is used more than you might think to keep the left front down. at one time this was on the grt lm set up sheet and you'll see it on a lot of dirt latemodels.

                      I've seen a lot of fast guys with lead bolted on the L.F. frame tubing. I see a lot of weight bolted to the R.F. of that Spaulding dudes car from the Dirt Knights show. I've never seen weight bolted there. Can someone please explain why he is putting it there?

                          They are trying to get the car to lay over on the RF. Weight on the Front of a car seems silly. Lead should be kept close to polar in the chassi. A balanced setup can be ajusted by raising or lowering lead.
                          Any weight higher then the cam on the engine will transfer to the R side,more then if its lower then the cam!
                          More RR drive or a softer RF sping will help the wheelie problem.

                            usmts has a rule if you run an open alum headed engine you have to run the wt in front of the mid plate. some say if they have to mount it put it were it'll do so kind of good and from what I'm told this plants the rf tire to the track and they can drive in harder. if you watch spaulding on a tacky track he's never out of the gas the lr never drops look at show #9 t modfury.com

                              we have a shaw and we never run more than 40 pounds of bite , if we do it wont set the left front down at all , if you shorten up the left rear chain that will help also,if you do put lead on it put it on the left side down low by the frame if you can, we did it one time on a loosegruff we had and that seemed to help with the wheelies , good luck
