Pair of adjustable spherical bearing mounted caster arms for Lexus IS300 and Altezza. Increases tire clearance for up to 70 degrees of angle when used with our front set & settings. TIG welded solid rod, CNC solid steel OEM style 2 bolt connection, CNC clamping rod end receiver, PTFE lined maintenance free 22id spherical bearing in forged rod end with clamping double threaded adjuster that allows on-car caster change when you loosen the 2 bolts to the FLCA. Contrary to popular belief the caster is adjustable due to the hole diameter in the FLCA where a small change in this inboard mount moves the outer ball joint quite a bit. Tighten the 2 bolts and clamping adjutments to finalize the caster setting change.
