SUSPENSION GEOMETRY
NEWLY REVISED
by Ted Mitchell
Here are some suspension geometry figures I have developed for the STOCK (original springs, shocks, tires, wheels, etc.) Pantera. Any comments and or suggestions are welcome.
STOCK PANTERA
NOTES:
1. Without 1973+ steering rack spacer
2. Ride height per TSB (7.28in. front, 6.89in. rear)
3. Stock shock absorbers with rubber snubbers. These snubbers only allow about 3/8 inch bump travel before
engagement which raises spring rate considerably, but my suspension program doesn't let me consider the additional
progressive spring rate which would limit roll even more.
4. All linear measurements in inches (including grid on diagrams).
5. *The vertical CG height of 17 inches was a GUESS on my part because I have been unable to find any reliable
figure.
