This series of adjustable trailing arms are designed to modify factory camber - toe and track on the rear of Subaru Impreza and Liberty. Use KTA107 as an economical solution for lack of rear toe adjustment particularly on Impreza GD-GH (MY01- on) series. This kit is supplied as 2x adjustable front arms and matching rear arm poly bushings. KTA108 and KTA109 utilize 4 complete adjustable arms with performance low compliance bushings. The result is greater range and more precise adjustment and a more direct connection between body and rear suspension delivering more predictable dynamic behavior. Left-right-hand thread adjustment turn-buckle nut allows for easy on-car adjustment.
