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

Rear knuckle holder summary

This alloy rear knuckle arm holder is made for Kyosho Mini-Z AWD configurations, matching MR-03 AWD style mounting. The component establishes a rear toe-out of -0.3mm and is provided as 1 pcs for single-side replacement or experimental setup adjustments.

The holder secures the rear knuckle arm to maintain the chosen toe geometry. Because it is alloy, the mount resists deformation and preserves alignment while other suspension parts remain unchanged, helping you isolate toe impact during setup tuning.

Use this holder as a direct replacement for the OEM rear knuckle arm holder on compatible Mini-Z AWD cars; fit using existing hardware and double-check fitment on MR-03 AWD variants before running. Try small, repeatable toe changes with this part to measure effects on mid-corner stability and exit traction.
