yes the torisional rigidity figures of the E46 agrees to what i have:
sedan 18000Nm per degree of torsion
sedan w/fold downs 13,000Nm
sport wagon w/fold downs 14,000Nm
coupe w/fold downs 12,500
convertible 10,500Nm
and the Zed4 is indeed very rigid. They have added lots of cross member conectors underneath and above the front strut towers...reara are not necessary as they seats are not fold down...
so the new Mustang with 21k+ newton meters of force to twist the chassis through a degree is very very good...defnitely a vast improvement over the current chassis...
