MUSTANG II chassis

     The lower control arms each have a compression-type strut which angles rearward and inward, anchoring to an isolated subframe structure suspended between the front side rails of the underbody. This "mini-frame," imparts more of a body-on-frame big-car ride to the Mustang II. Part of the road shock vibrations are routed to the mini-frame instead of to the body structure. The mini-frame dissipates them into the mass of the engine-transmission assembly, which is also mounted to the mini-frame.
     As is customary with a lower control arem strut, the compression strut allows the front wheel to move rearward slightly while encountering heavy road shocks. But in addition, Mustang II's front suspension geometry is arranged to cause the wheel to move rearward as it moves up in response to a road jolt. This built-in wheel recession soaks up some of the forece of road shocks before they have a chance to reach the body structure.
     A link-type stabilizer bar is standard. It connects both lower control arms through rubber-bushed vertical links to help reduce roll when cornering. Shock absorbers, mounted within the coil springs, are easily accessible for service. Upper and lower ball joints are of a reduced-friction design.


REAR SUSPENSION

     The leaf spring rear suspension also has been modified over that used previously. Expanded use of rubber isolation is notable. Iso-clamps provide full butyl-rubber cushioning between the axle and rear springs to eliminate metal-to-metal contact. Rear shackle attachments incorporate exceptionally large rubber bushings (1-7/8-inch versus 1-inch). Shock absorber mounts also include added rubber for softer ride control and "feel".
