Alignment Spec Questions, another alignment thread Options

[John]

I have a few questions that some of you smart people out there might be kind enough to answer for me.

I am wondering how you convert angular toe-in (per factory specs) to inches of toe-in.

I could convert angles to inches if I knew where to measure. Is the toe-in measured at the rim, at the tread, at the sidewall?

Or am I reading the chart from the factory manuals incorrectly?

What are the "factory" settings for:

Front Caster
Front Camber
Front Toe

Rear Camber
Rear Toe


On another note, RIDE HEIGHT.........

The front ride height is measured as the DIFFERENCE between the center of the torsion bar and the center of the wheel rim.

How is the rear ride height supposed to be measured, and what is the 'spec'?????

Thanks for replying.

My questions started this weekend when I aligned the track car. I started out by lowering it to where my dad wanted it, and then corner balanced it and finally aligned it.

The car seems to be tail heavy. It is a 3.2 with a 915 trans. 9x16" wheels on all four corners Kuhmo Victoracers (245/45).

23mm torsion bars
21mm Front Sway bar
400# Rear Springs

My percentages ended up as follows:

LF = 20.4% RF = 17.7%

LR = 32.6% RR = 29.2%

As expected, the driver side is heavier (it included the driver), but the diagonals worked out fairly well.

I aligned it with as much negative camber as possible and keeping both sides even.

LF Camber -1.766 deg RF Camber -1.733 deg
LF Caster 5.38 deg RF Caster 5.23 deg
LF Toe 0.03 inches RF Toe 0.03 inches

LF Inc Angle 13.26 deg RF Inc Angle 13.36 deg

LF SAI 15.03 deg RF SAI 15.10 deg

Total Toe 0.06 inches

LR Camber -0.88 deg RR Camber -0.93 deg
LR Toe 0.03 inches RR Toe 0.03 inches

Total Toe 0.06 inches

Thrust Angle 0.00 degrees

I thought this information might help explain what i'm attempting to figure out.
