This is a 2 bushing kit that includes longer bolts which is used to eliminate the possibility of the front lower control arm to move within the subframe causing caster and toe changes especially during aggressive driving on the track. We have experienced the OEM bolt to loosen when on the race track and then start to ovalize the the 14mm hole in the subframe. When this happens, the lower control arm moves in the frame causing caster and toe to change on the track. This bushing allows the bolt to be centered in the subframe and stops for any potential ovalizing of the subframe hole. This also gives a consistent caster setting on the chassis.
Due to the inconsistent bore of the subframe by Hyundai, it is suggested to sand the bore for any imperfections inside that might bind the bushing when installing.
