Pair of Rear Upper Arms for XE10 IS300, Altezza and 97-2004 GS and Aristo. Laser cut, CNC bent, TIG welded DOM steel. All maintenance free spherical bearing joints with replaceable Chromoly outer joint taper pin. Designed for great frame clearance on lowered cars. Adjustable +/- 16mm compared to OEM arms. Extra negative camber is possible i you remove jam nuts and shorten the adjuster rod end. Camber is ideally an equal adjustment on the upper and lower arms so that the axle length does not change. If you try to make major camber changes on just one of those arms then you will effect axle life.
