    Take turns out of right rear and add turns to left rear. It will get there do the same on each side. 5 out 5 in and so on.

      Get your left% , your rear % , your ride heights , and your bite . That's it , don't worry about what each front weighs . It's gonna be what it is when you get the other things I listed. Only way to do what you are trying to do is change left % , try it on a calculator , that'll answer your question.

        Sounds like spring rates are wrong if the ride heights are correct. may double check them

          "if the front is right the bite is in the car the wrong way"

          they gave you a front weight that is right or wrong?

            We had a car like that and the cross member was closed up on it. Set the bite like it should be and go run it. Give the car what it wants after that.

              Make sure the cables for your scales are not plugged in wrong

                If it is what you say it is, and the scales are hooked up right, it means you are very low on left side weight. If you have a car that is 100 lbs heavier on the left side than right, and you had 100 lbs LR bite, your front wheels would be even. If it had 50 lbs LR bite, you would have 50 lbs across the front.

                  I have had this happen before. Check the motor location. You may need to move it to the left a little. It helped with mine and it helped it turn better.

                    this is great info. Thanks. I have a question about the bite as well, my chassis manufacture recommends 40 lbs bite. It's been a while since I've spoke to him, but I am thinking he told me to run the LR more than the RR. For instance, 690 LR and 650 RR. This would make 40 lbs RR bite, right? Or do I need the RR heavier than the LR?

                      Most chassis builders run LR heavy bite. There are some that don't.

                        Double check your scales locations, I did this a week ago and was so frustrated I couldn't figure it out. Checked scales and had rears switched around. Easy to overlook when someone is talking to you/ or on the phone and not paying attention
