It matters alot on full scale cars where the springs in the front might be twice the rate of the rear. With our late model the front springs are 500# and the rears are 225#. in that case if I adjusted the front the same as the rear I raise my front ride height when I adjust wedge. The same adjustment on a twice as heavy spring makes twice the adjustment. So the fronts need to be turned half as much as the rear. On a Touring car the spring split is minimal so the split isnt noticed. But if there was a 15# in the front and a 30# in the rear you couldnt make the same adjustment.

as i was crew chief and engine builder for an open wheel modified it should not change your ride height going even turns in and out on opposite corners.modifieds dont even run the same springs on all for corners as many oval cars dont.why your car does that i dont know but it shouldnt as all you are doing is making the light springs carry more weight and the heavy ones less.

The heavier weight springs are doing twice the work as the lighter springs. Making the same adjustments to the front as the rear makes twice the adjustment in the front as you are doing in the rear.

i always adjust the springs evenly in and out and never had ride height change,like i said i dont know why yours does .so i guess we will have to agree to disagree on this one and everyone can take both our opinions for what they are worth.

I guess. I learned that from Joe Garrison from GRT race cars and I have verified it on the scales.

i llearned from a local track record holder myself(ie oldtimer),i dont know who your guy is but im not from out that way.you may do something different in your setting up your car than i did as we used longacre scales also.but not important as long as the end result is the same.

Interesting. But did you calibrate the scales before hand? The problem with this kind of system is that are all four scales have the same reading.

I would still level the board and check the scale surfaces themselves with a small level.

What you could do is buy 2 small levels and attach it to the horizontal and vertical sides of the board.

speedy phat is right on the issue of heavier spring will over power the opp. corner when it is a lower rate..except most late models or modifieds like ellis or harris have fine thread weight jacks in front and rears are usually coarse thread.. any time you crank a turn in the right front it will lower the ride on the left rear..
