Total weight of the car and non-changing spring placement is the key here....you can take water out of a jug and pour it into another jug, and as long as you dont spill any, you still have the same weight....in both jugs...wedge works this way in a car. It is a very useful tool once you learn how to use it to get a car hooked up because there are many ways to do it....

This is the easy way to remember this....
if you want to add weight to 2 wheels of a car at the same time, ie rear tires, left side tires, front tires or right side tires, then you must increase the weight of that side of the vehicle to increase them simultaneously. If you want to increase the weight on 1 of those same 2 wheels, then you can adjust wedge, which will decrease or increase a certain wheels weight with the same total weight within the car. Think of it more as distribution of the weight you already have, and if you want to distribute the more weight, you have to add weight.

hope this helps.

Turning weight jacks wont change left or rear %. The only way to change left or rear is to physically add or move weight on the car. By moving weight from the front to the rear you are moving the center of gravity rearward which puts more weight on the rear tires. Same with moving weight to the left. Thats why wyou should try to keep the front end light and mount everything as far back as you can. Then add the ballast that you need.

Also, if you take 10lbs of air out of each the front tires, then add 10 lbs to each of the rear tires, you have not changed the front/rear % one bit.
But I don't know why....

Front to rear Center of gravity is the key here. If you can move weight to the rear from the front, you would obviously raise the rear %. The only way to affect rear % is to move the CoG line of the car. Nothing else will affect front and rear %.

turnitleft-whipitright Bottom line is you are making a teeter tooter out of the car when you set wedge.When you turn down on the R.R adjuster& the L.F. adjuster you stand the car on those wheels more an on the L.R.-R.F.less. This lowers wedge an will useally tighten you in & loosen you off.You can change the tire size on any corner an do the same to the weight.It does work around the center of gravity & polar moment effect.When you have time measure each spring on your car with it sitting on the floor,get in set down an let it settle an have some one remeasure the springs .Bet you will be suprised which one compresses the most.Just set the cross weight where it works the best an have a good ride. cd2
