This aluminium alloy rear knuckle arm holder is an aftermarket replacement part for Kyosho Mini-Z AWD cars and is supplied as 1 pc. It provides a +0.1mm toe-in offset so you can fine-tune rear geometry without changing the upright or hub spacing.
Functionally the holder sets the rear knuckle arm to achieve the specified Toe In +0.1mm. On a Mini-Z AWD MR-03 chassis this small adjustment is aimed at improving turn-in response and corner balance on technical indoor tracks.
Fitting is straightforward: remove the original holder, position the alloy piece at the same mounting points, and secure using the original screws. Use the correct hex tool, do not overtighten fasteners, and recheck wheel alignment and clearances after installation. Inspect surrounding parts and bearings while the car is open.
A tidy upgrade for club racers and weekend tuners wanting reliable toe changes.
