      Coilover ride height adjustments different on all sides when corner weighting, got?s

      I had a wheel alignment done two months ago but did not mess around with making my ride heights perfect. They were about 1/4 off from left to right front and rear. And the alignment shop thought i was crazy ti be worried about this.

      now i recently had a friend bring over scales and we made alot of adjustments to make the car almost exact weight and height all around. Now my passenger side front required a ton of less preload on coil spring versus the left side.

      now my car has a slight pull to the right. The side i removed spring preload to adjust weight and ride height


      here are the tech questions i want some of you guys to answer. Being that i removed preload from that front corner do i then need to increase compression and rebound on that coilover assembly only and make those adjustments different from the other side? Is this what you do to compensate for the changes in spring preload you add shock valving?

      i am just trying to understand if this is the case and how the heck can you make the car feel right if all 4 sides have different spring preload and different shock valving fine tuning



      should my shock valving be the same for the front left and right? Same for the back of the car


      reason im asking is with toe plates my toe hasn't changed much but im trying to see what is causing the pull to the right and my only thought was the release of spring preload on thr front right side

      When adjusting the preload on a c/o you are not adjusting the rate, Just the load. Since the rate stays the same, shock settings will be the same side to side. So a spring with a 450# rate will support 900# when compressed 2" If you preload that spring another 1/2" it will support 1,125 but will still have a rate of 450#.

      My guess is that if you go back to the alignment shop you will find that you have more negative camber and more positive camber on the passenger side due to that side sitting lower now than when aligned.

      now this makes sense i kept thinking these were progressive rate springs like i use in my modern performance cars which change their rates with preload. im expecting to get a new alignment any day now if the rain stops and i get some free time.
