if u add a rubber bush, ur abs will kong easily..because when u over road bump fast, ur car jump up, then ur spring will extend to it's ori size which is even longer than ori abs..if with bush, the spring will extend more fast and ur abs will being pull out..when ur car land, the abs will back again..after some time. ur abs sure kong....that's wat i experience in my car after add bush...the best is change to other car abs..i think nissan some model can fit in....
