Before I had a 6 degree beam and 20 year old shock absorbers that were "hot rod" design, they had lost their adjustability for damping and had the wrong spring rates. We also found that the beam was sitting very slightly to one side and a little out of alignment causing some driveline shunt (think it’s called that) - rear steer.
the front compression struts mounts were in the wrong place and the turrets were so weak Jonfoc was surprised the (too stiff) fronts had not punched up through the strut tops.
the front 4wd beam was also poorly located and needed repositioning. We also had an Ackermann issue that we may be able to solve with shorter steer arms.
the new setup will have the modified Wrc rear cradle on Black art design coilovers and Wrc top mounts, the big improvements should be huge weight loss due to T45 cradle and connecting rods, properly located rear strut towers with top mounts as opposed to little boxes that did not allow any adjustment as the springs used to rub the shell. Correctly specced springs, all chamber adjustable etc. The shell had very little strength with just a bolt in cage that had been chopped about with no rigidity for the rear suspension. Every time I softened the springs the car got better but was over damped on the front as designed for 300lb springs and valves accordingly for escos which is WAY heavier. The rear probably had very little damping .
the cage now obviously ties front to back, properly located tubular t45 front cradle at the right height with correct location of comp struts and black art design dampers same as on the rear. The track will all be straight and the track also widened to the max the shell will allow.
the bladed roll bars are having modified arms to locate better too.
i have written this in lay person terms so please excuse errors in terminology and understanding.
