stiff bushing does not affect handling, it is the natural substance fo the material that caused the problem.
PU being a sticky substance, causes the biggest handling problem by binding. during movement our suspension arm moving up and down the bushing suppose to allow twisting movement and being sticky, PU will bind and when forced to rotate, it iwll start wearing by grinding against the arms. thats why PU bushes always give out annoying "yik yik" sound. the sound not just annoying, it means your bushes is starting to wear. another problem of binding is that it will create a lifting effect insted of planting.
The problem with DC5 basic mcstruct set up is lack of front end feel or lack of feedback to driver.
The ultimate setup for DC5 / EP3 / ES is t installed offset front lower arm pillow ball bushing together with roll centre adjuster. The "offset" bush will increase castors that not just allow more outside wheel camber angle, but also increase steerign feel. RCA is neccessary to counter roll, as mcstruct setup does not allow high spring rate (unless single purpose race car), RCA will help to reduce roll.
As for the tie rod end problem, hardrace is currently R&D a up right tie rod end to solve the lowered car toe setting problem as well as ..............just wait for it to arrive and test it yourself.
