OVERVIEW
The front suspension features long travel McPherson struts to optimize on
and off road performance.
The suspension components are mounted on a subframe. The subframe is
mounted on four bushes which have differing compression rates to absorb
lateral and longitudinal loading. This provides a rigid platform for front
suspension cornering loads, frontal impact absorption and also provides a
towing point for off-road recovery.
