Kyosho Mini-Z AWD Alloy Rear Knuckle Arm Holder (Toe Out -0.3mm) by GPM MZA031R/-0.3  [MZA031R/-0.3]

Rear knuckle arm holder overview

This alloy rear knuckle arm holder is a scale accessory designed for Kyosho Mini-Z AWD applications, specifically matching MR-03 AWD layout expectations. The part sets a rear toe-out of -0.3mm and is supplied as 1 pcs for single-side replacement or experiment in tuning setups.

Functionally the holder provides a fixed mount for the rear knuckle arm to establish the specified toe geometry. Using an alloy holder maintains the intended mounting position without altering other suspension components, making it suitable for stepwise tuning where toe adjustments are tested independently from shocks or roll bars.

Installation is intended as a direct replacement for the stock rear knuckle arm holder on compatible Mini-Z AWD platforms; installers should use existing hardware and verify fitment on MR-03 AWD variants before track use. Use this part when attempting small, repeatable toe changes to evaluate their effect on corner entry and mid-corner stability.
