    Use a shorter spring on left front so you will have more adjustment

        1 In rf, 1 out lf
        2 in lr, 2 out rr usually adds 50 lbs of bite and keeps ride heights the same
        Turn LEFT, Vote RIGHT!

          Scales are good, scaled it 3 seperate times. I have a 10" spring in LF now. Only thing i can do is take out the take up spring on LF then i can back it off about 5 more turns.... The thing I find really strange is that even if I take a bunch of turns out of the RR, it doesnt lower the RF and it really doesnt lower the bite as much as it should. I took 7 turns out of the RR and it didnt change the RF at all.... another weird thing is if i take turns out of the LR,, it really doesnt drop ride height much or bite numbers..because even though im taking turns out of LR, this causes the frame side jbar point to come down, which in turn moves the rearend to the right, which in turn actually moves the bottom of the LR spring point over to the right as well, which just keeps the height and keeps the weight on it,, kind of cancels each other out... this car is rigid, which i like because you can really feel any changes... just doesnt work the same way on the scales like any of the other cars ive ever had

            Have you checked to make sure your birdcage isn't binding at that point near ride height. I would take the rods off and spin the cage the whole way around. Also make sure you don't have a problem with your shock like cavitation or a bowed shaft.

              I will check both of those.. Almost brand new cages.. when you push down on rear everything moves nice and smooth but at this point im open to all ideas. thanks

                      100 lbs bite

                      Seen this many times, put one round in the right front, take two rounds out of right rear and put two rounds in left rear. your left front ride height will move so keep that tuned in. this will also add 50lbs of bite if you want 100lbs then repeat the above but do it in increments add 50lbs at a time do not try to add 100lbs at once do 50 at a time. your very welcome

                        The RF is already at the top end of spectrum, dont want it any higher. Same thing with RR, already almost too low, and same thing with LR, already too high.. so each of your suggestions will only make each of these worse. Thats my problem. On most cars Ive owned, you would be correct, by adjusting the RF up, it should bring the RR up as well and then you just take a turn or 2 out of RR to get it back to correct height. This car doesnt work that way at all which is why it doesnt make much sense.

                          Remove an axle, see if that makes much difference.Then drop 2lbs of air from the l/f ,add to 2lbs to the l/r.

                            If you have changed spindles recently make sure you have correct ones. I fought similar problem only my car had 100 right rear bite when rides heights were right. Turns out my new left front spindle the snout was down 1 inch lower on spindle so making your ride height standard actually would be like making it one inch taller with correct spindle

                              im sure your right...but make sure scale leads are correct ,,ive see it many times and just check stagger again,, also i had a new rf upper arm made with to much angle not letting car move ,,just a possibility

                                sounds to me something is in a bind. i would take preload out of fifth coil while scaling, disconnect left front control shock(aka dummy shock), and slide left rear axle out of flange. put car back on scales and shake it down. Like said in above posts make sure scales are plugged in correctly and you are using the right ride heights at each corner. Good luck i know it sucks having scaling issues.
