Tue Jun 12, 2007 2:56 pm

I am leveling out the bug after the drop spindles and have almost got it,What I am needing to know is if moveing the inner torsion one spline one way gives you 9 degrees of change and moving the outer the opposite way gives 8.1 degrees,you have a change of .8-.9 degrees.What does this equate to in inches ,I need to raise the left rear 1/2" to get the ride perfect.I am prob going to jump on it tonight but figured it could save me a bit of time if I knew how many splines to move to get 1/2 ".I searched but no specific answer

you da man,That should be in the sticky about lowering the rear end :D

Wow that diagram would haved me a couple of hours this weekend.

Thanks for the chart. It helped me a lot. I only had to adjust one side but it made all the difference not having to guess. It took me a little over an hour.

... And for you guys that are adjusting just that .55 it may not look like you haven't changed any thing after making the adjustment but you have.
You will not see it till you get the car back on the ground.

Hey, Glenn: Do you have a similar chart for raising the rear end? Or can I extrapolate backwards from the chart you posted? I only need an inch or so. Thanks!

I need to raise mine too...

Great chart Glenn, Thank you.

I just bought this 59 and I am trying to lower the rear, but I think someone has already tried to- i took off the spring plate and unbolted the rear swing axle, but it didnt need to be plied off of the sitting edge. I want to lower it only one notch but need to know what angle is stock. the swing arm is sitting at 0 degress- any suggestions. I went up one notch and it read 9 degrees but there doesnt seem to be any tension. help

On the chart, does "+1" mean rotating the torsion bar clockwise?

It depends on which side of the car you are working on.

Basically it refers to moving the axle end of the spring plate up or down.

So on the right side thats clockwise and on the left side its counter clockwise.

Thanks for the chart and advice guys.... I have a couple of more questions: what angle on the spring plate am I measuring? And how do I just adjust camber? My left and right sides are at the same height, but right size had more negative camber...

The pan of the car should be level, or zero degrees. Then from there you will measure the angle of the spring plate.

Use on of those ^^ I call it an angle finder.

What year is your car? On a swing axle, camber is not adjustable. Toe is semi adjustable though.

It's a 66. I have an angle finder. Do I measure the bottom of the springplate? The top? In relation to the ground or the rest of the car?

I just measure the angle in relation to before and after.

1)Decided how much lower you want that side of the car and using the chart above determine how many degrees that equals.
2) Then, take everything apart and drop your spring plate WITHOUT removing it completely from the torsion bar.
3)Measure the angle of the spring plate with your angle finder. Just set the angle finder on top of the spring plate to get the angle.
4)Now you've already used the chart to determine degrees you need to rotate the spring plate so using the inner/outer + and - numbers adjust accordingly.
5)Once you think you have moved everything accordingly, re-check the angle of the spring plate. The difference between the beginning angle and the new angle should be exactly or pretty darn close to the angle you determined in step 1) above

The angle finder is more of a "check" device. It's not required, but using it usually means you'll get it right the first time.

I know this thread is super old, but I'm in the middle of this job and I have some questions: What does the foot designation refer to? For instance, the first increment drop, according to the chart, is a 50' increment? That's of no use to me; I need to know the degrees difference it is as I am using an angle finder app on my phone.

It goes back a ways.. I guess you skipped Geography class. :lol:
But a valid basic question nonetheless..

There is some History involved.. that I'm sure most slept through..

Ill cut to the chase...

1 minute of arch is equal to 0.0166667 degree.
Do the math..

Or be typical web lazy and punch it in.

This is how I easily remember..
Think of 360 degrees as a clock.... :-k .. an old style dial clock that is.. ya know the one with the seconds, minutes and hour hands.. :wink:

15 minutes is .25 (of 360 or 1 degree)
30 minutes is .50 (of 360 or 1 degree)
45 minutes is .75 (of 360 or 1 degree)
60 minutes is 1.00 degree (of 360)

Like I mentioned... it goes way WAY back a ways.. ..
To the very basis of how time is kept..

Thanks for this; I appreciate it. Yeah, if life depended on math skills I'd be dead.

OK, so I want to lower my car the least amount - 1 spline inner, 1 spline outer. If the measurement is 50', wth does that mean in terms of degrees? I'm using a protractor that only measures in degrees. That chart is confusing to me.

Let me get specific: If my present spring plate angle is 15.1 degrees, if I turn the torsion 1 inner, 1 outer what will the new measurement be? According to the chart above it would be 50', but that means nothing to me.
:-k

60' = 1 degree
50' = a little less than 1 degree.

So if you do one inner & one outer the opposite direction you will get a little less than one degree difference than your starting point. This will give you approximate 1/4" of actual drop or raise of the car.. If you are at 15.1* now you will be at 14.3* approximately.

I wish that chart was still there.
