Kyosho Mini-Z MR-03 AWD Rear Knuckle Arm Holder (Toe Out -0.3mm) MZA031R/-0.3 by GPM  [MZA031R/-0.3]

Rear knuckle arm holder details

This machined alloy rear knuckle arm holder fits Kyosho Mini-Z AWD layouts and is intended for MR-03 AWD style setups. It establishes a rear toe-out of -0.3mm and is supplied as 1 pcs for a single-side replacement or for tuning trials.

The holder provides a stable mounting point for the rear knuckle arm to lock in the specified toe geometry. Alloy construction preserves the mounting location without altering other suspension components, making it useful when testing toe changes independently from shocks or anti-roll bars.

Installation is a direct replacement for the stock rear knuckle arm holder on compatible Mini-Z AWD platforms; reuse the existing hardware and confirm fit on MR-03 AWD variants before track use. Fit this part when you need repeatable small toe adjustments to evaluate turn-in and mid-corner balance.
