Available Track Widths
The track width is measured from the outer surfaces of the wheel
bearing / hub assemblies... often referred to as "hub-to-hub" measurement.
The photo below tries to illustrate this... Don't forget to account for
roughly 1/4" on each side for the brake rotor thickness.
The upper and lower control arms are of fixed length... The variations
in track width are accomplished by changing the IRS center section. Call
for details on the best track width for your body / chassis style as well
as wheel / tire sizes you are using on your build.
