The factory setting tool is designed to be used between the upper and lower mounting points of the front shock absorber. For standard E Types, where the torsion bars etc are in perfect condition, the manual calls for a distance of 17 13/16" between the two shock absorber mounting points. When heavy duty torsion bars are installed, the additional strength of the torsion bars means that a distance of more like 16 1/4" will result in the correct ride height, depending upon the precise strength of the bar.

The following table shows the approximate settings we recommend for the various torsion bars available from Classic Jaguar. Unfortunately, despite the rather quaintly precise factory recommended measurement, let me reiterate that we are not talking an exact science here. A certain amount of trial and error may be unavoidable.

Note: We actually recommend having the ride height at the front of a six cylinder E Type a little lower than those recommended in the workshop manual. The car will handle better with the nose about an inch lower than 'standard'.
