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

Rear knuckle arm holder for Mini-Z AWD

This GPM aftermarket rear knuckle arm holder is an RC-scale replacement part produced for Kyosho Mini-Z AWD platforms, supplied as 1 pcs. Machined from alloy, the component provides a fixed Toe In offset of +0.3mm to alter rear toe geometry without modifying the stock steering blocks.

Intended role: this arm holder is a tuning part that changes rear toe angle to influence corner entry and mid-corner stability on small-scale tracks. Use it when you need a subtle increase in passive rear toe-in for improved straight-line tracking or a different balance between cornering and transitional grip.

Installation notes: the part replaces the standard rear knuckle arm holder on compatible Mini-Z AWD MR-03 AWD setups, reusing existing fasteners and linkage geometry. Basic tools such as a hex driver are sufficient for removal and fitment; verify thread engagement and clearances after installation before running the model.

Materials and handling: alloy construction provides rigidity compared with standard plastic holders, which can affect feel and feedback through the rear suspension and toe link. As with all RC-scale alloy hop-ups, check mating surfaces and fastener torque to avoid loosening during use.
