Its not nice to try to trick a old fool! Just get the ride heights and rear bar settings and it should come around on the scales! Then the left ft. jack bolt will tune it right on in the house! I would get rid of that easy up and check my post on shock theory 5 lt. 3 rt.ft. or at least softer than left! 3s or 4s rear evenly makes for smooth transfer both ways! I hope your numbers fit the picture and not as is now! Do you have scales to work with? I have set them up and be ok when they hit the scales and track and some are females and needed hours to find a bad new spring! Less movement and more transfer needed! Get any weight as far rear and low left as you can to improve transfer! Keep the info coming and we will get it there!!! More rear percent won't slow you down or sling once keeping left rear in tact! The weight makes the left rear the center of all turn factors!

I had my weight high and on the left rear behind the axle. I was running afco shocks, heavy LF extra heavy RF I don't have my book here with the #'s. I also had Pro shocks on the rear with and easy up on LR 50/50 RR. Springs where 1100 RF 900 LF 225 LR 200 RR and it has the metric 4 link. If I remember my % were 55% Left 50.5 Rear with 49.5 cross. 1/4 inch toe out on the front. We have to run the a arm mounts in stock location so my LF was maxed out and was able to get camber +1 and RF was -6 I forget the caster split but the car would turn left if you let go of the steering wheel while driving. Looking at the pictures it would seem that Ackerman would cause toe in in the turns when rolled and loose the bump steer to be in control rather than you when you steer one tire only in the direction of travel! The left should turn left more left than the right at all times and setting hold true to the job at hand! When on the throttle and off the corner the front lift should correct the toe in as to be a even setting as not to bind the chassis! Having a steady ft. end requires little movement or roll to keep control of needed, pre-set angles to steer both sides properly! Leaning left to start with is like the lead in the rear, there are far more benefits than most see at a glance in holding settings with in controlled preset ranges to get the job done correctly with out all the extra fuss or movement! While turning left on its own is a good thing it is in no way a sign of being correct elsewhere once turning the steering wheel or rolled over! Even with our corrected ft. end we run from 1/2- 3/4 toe out but you never see it unless sitting still! It too wishes to turn left on its own at all times! Traction and right rear transfer is best done by weight transfer and helped by preloaded springs to push it there! If things keep moving such as tire or spring pressure and transfer is lost at the other end of the cross by coming off the spring's preload, it is really hard to get good transfer and side bite! Can you see the loss in too much movement of the frame at the springs! This is why setting a balance of preloads to hold it and transfer rather than roll and give it away makes sense to me!

So how do I correct this? I understand the correction in toe that's easy. I have to fix the bump steer, yet we have to use all stock components, use of 11 inch spring in LF will drop that corner a bit.

Once you change ride heights and get percentages, the rear and ft. should be close but is critical to bar angles on tie rods as well as rear! You may not have to change anything as far as parts if it has not been butchered to fit another setup! See what it looks like once the ride heights has changed! Have you found enough post on my settings to see how and why I do it this way? caster and camber settings? Rear bars? Its all there somewhere if you have been keeping up! Don't let it alarm you as most is just a eyeball setting for me! I'll be here to walk you through any part needed!
