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

Alloy rear knuckle arm holder for Mini-Z AWD tuning

This aftermarket rear knuckle arm holder fits Kyosho Mini-Z AWD MR-03 AWD platforms and is supplied as 1 pcs. Machined from alloy, the part adds a fixed +0.3mm toe-in at the rear to alter toe geometry without changing the stock steering block.

Setup purpose: use this arm holder when you want a subtle increase in passive rear toe-in to improve straight-line tracking and reduce snap oversteer at low speeds on carpet or tight club layouts.

Fitment and installation: the component replaces the factory rear knuckle arm holder on compatible MR-03 AWD variants and reuses the original mounting points and hardware. Basic hand tools like a hex driver will complete the swap; check thread engagement and clearances before the first run.

Material notes: the alloy construction increases rigidity versus plastic holders, which can change rear suspension feedback. Inspect mating faces and torque fasteners to recommended tightness to prevent loosening during use.
