Raising
the ride-height at one corner increases the weight on that corner, as well as
the diagonally opposite corner; the other two corners will lose weight. So since my right rear is the highest AND
the heaviest, i think lowering it will really help with the numbers. and left
front is heavier than right front, so that same change (lowering right rear)
will also help the front become closer to equal. |
|
Cross: |
if cross is over 50% =
"wedge". If under = "reverse wedge". Reverse wedge =
turns left better but pushes going right….I think |

DAY TWO: |
|
|
|
|
|
|

|
|
|
|
|
First
Adjustment: I was told motion ratio was .6, so I took a
guess on how many turns to lower the rear coilovers. There are about 10-12
rotations per inch. I took a guess to lower the Left Rear 5 turns and the
Right Rear 6 turns, and it turned out perfect. Ride height at every corner is
now 25.25 inches. Rear sway bar is disconnected but front is still connected.
Still 1/4 tank of gas and I will put more in tomorrow night. That will
improve the distributions I believe. |
