This alloy rear knuckle arm holder is designed for Kyosho Mini-Z AWD platforms as a direct replacement or hop-up to refine rear toe and sharpen steering response. The component is set at a -0.4mm toe out, measures 1.0mm thick, and is supplied as 1 pcs for one-side replacement or targeted tuning swaps.
Design and fit: machined alloy construction gives a firmer mounting point compared with stock plastic pieces, helping to keep wheel alignment consistent under load. It fits MR-03 AWD arrangements found across the Mini-Z AWD range and installs into the same rear knuckle arm mounting positions as the original part.
Tuning role: the -0.4mm toe out nudges rear tracking outward to influence rotation and mid-corner grip. Fit this part when you want quicker turn-in or a subtle change to rear traction, and combine it with roll centre and shock tuning rather than changing multiple geometry items at once.
Installation notes: this is an aftermarket alloy component intended for RC Mini-Z AWD use only. Inspect existing fasteners and bearings during the swap, and re-torque mounting hardware after a short test run to confirm fit and clearances.
