durable yes... handling performance, if u dont push ur car to the limit, u most probably cant feel much...
personal experience... i swapped mine to superpro lower arm bush... during installation, my mechanic didnt tighten the lower arm strong enough... end result my lower arm was dangling dangerously with a loosen bolt... i felt no change in alignment as the car still tracks straight... the strong bush held my lower arm in place well enough...
