Kyosho Mini-Z AWD Rear Knuckle Arm Holder MZA031R/+0.3 by GPM  [MZA031R/+0.3]

Precision rear knuckle arm holder for MR-03 AWD

Engineered for Mini-Z AWD MR-03 AWD platforms and supplied as 1 pcs, this CNC-style alloy rear knuckle arm holder provides a controlled +0.3mm toe-in offset to precisely alter rear toe geometry without modifying factory steering blocks.

Performance intent: designed to deliver repeatable toe settings that improve straight-line tracking and reduce transitional oversteer, the component is suited to fine-tuning handling on tight club circuits and carpet surfaces.

Installation and service: the holder replaces the OEM rear knuckle arm bracket on compatible MR-03 AWD chassis, retaining original fasteners and linkage geometry. Install with standard hex tools, verify thread engagement and clearances, and torque to specification for secure operation.

Materials and build notes: constructed from alloy for enhanced stiffness and longevity compared with stock plastic parts. Check mating surfaces and fastener torque periodically to maintain fitment and prevent play under load.
