GPM MZA031R/-0.1 Kyosho Mini-Z AWD Rear Knuckle Arm Holder  [MZA031R/-0.1]

Mini-Z AWD Rear Knuckle Arm Holder

This machined alloy rear knuckle arm holder fits Kyosho Mini-Z AWD MR-03 AWD-style cars and is aimed at hobbyists seeking precise rear tuning. The single-piece item applies a -0.1mm toe out to the rear knuckle to modify rear-end behaviour while keeping knuckle geometry unchanged.

Built to replace the original plastic bracket, the aluminium holder offers a firmer, more repeatable mounting point for the knuckle arm. The part is sold as an aftermarket upgrade under the identifier MZA031R/-0.1 and suits Mini-Z AWD setups that follow the MR-03 AWD layout.

Fitting notes: use the original chassis attachment points and the stock fasteners unless a longer screw is required, check nearby suspension link clearances, and test the toe change on your preferred surface. This holder is intended to complement other suspension tweaks to improve traction and transient behaviour on carpet and small-track circuits.
