This alloy rear knuckle arm holder is engineered for MR-03 AWD compatible Mini-Z layouts to deliver a fixed +0.2mm rear toe correction. It functions as an aftermarket tuning component to refine rear alignment without replacing primary suspension elements.
The design shifts knuckle mounting geometry to modify rear toe response, aiding turn-in and mid-corner stability while remaining a direct-replacement part on compatible setups. Installers should confirm fit and retorque fasteners after test runs.
Compared with standard plastic mounts, the alloy option reduces flex at the knuckle interface and helps maintain toe settings under load during club sessions or practice. Use this part for precise handling adjustments.
