That detailed background of the history sure does explain why bumpsteer is inherent in the design of the M3W front suspension and I fully appreciate why the Suplex designed a shock and spring combo that minimised the impact. Clever use of spring and damper rates to minimise vertical movement about the static mid-point (where the track arms and wishbones are all parallel/horizontal) have clearly had the desired effect on Suplex-suspended cars.
I too have fitted the Spax adjustables, but due to header to shock interference, I cannot lower the car far enough to get the arms all aligned, so I have no choice but to run higher and look for a solution elsewhere......
... Which will be the empire kit, as this is a geometrically correct engineering approach, which no longer relies on the spring/damper design to minimise the degree of bumpsteer present during suspension travel. I hope therefore that the improved quality of the damping available in the uprated SPAX units will compliment the zero-bumpsteer geometry of the new upper wishbone to produce just as nice a drive as the Suplex approach.
Thanks PJB for that background info - it all makes sense now!
