To start with, the front springs are 60kg/cm (336lbf/in). Although they look rather flimsy the rear springs are 30kg/cm (168lbf/in). But as these will be placed slightly behind the axle, the effective spring rate is almost 45% higher compared to the original location. So they compare to 43kg/cm (241lbf/in) springs in the original location. A few test drives will be needed to determine if these springs are up to the job.
As the front dampers are placed “up-side-down“ in the strut the adjuster knob sits on the bottom of the strut casing;
