In terms of, is the whole running gear inter changable, and steering, column etc, rear beam etc
not fussed about interior and obviously doors/glass etc
just interested in the running gear differences
cheers
These are some of the changes from 3-door to Sapphire 2wd made by Ford.
Obviously the 4-dr shell was stiffer which has to be taken into account.
Spring rates went up from 106 to 118lb/in at the front and 263 to 286 lb/in at the back.
Damper rates were made softer in bump and stiffer in rebound.
ARB was increased to 16mm on back
Castor increased by over one degree
Camber made fractionally more negative
Kingpin inclination made slightly greater.
Front knuckles re-designed to lower the front roll centre from 144mm to 70mm
Work was also done to rid the tendency of the 3-door to "pitch" front to rear.
Much of the work above was done to create a less "nervous" car and for it to have better straight line stability
