I am looking at Konis and H&R springs, but I have read that some people's Konis sometimes become unadjustable because they can not turn the knob. Has anyone with Konis have this problem where you now can't adjust the firmness of them or just one of the struts? What other setup would provide good performance for spirited driving and maybe... maybe... track time, but mostly just spirited driving. I am thinking BAT Euro setup.
