This alloy rear knuckle arm holder for Kyosho Mini-Z cars provides a fixed +0.2mm toe-in at the rear to help refine handling. It is offered as an aftermarket hop-up for MR-03 AWD compatible Mini-Z layouts to tweak rear alignment.
The item is aimed at tuning: changing the knuckle mounting position adjusts rear toe behaviour to help balance turn-in and mid-corner grip without altering major suspension geometry. Installation is typically a direct replacement for the stock mount on compatible setups; check fasteners after running.
Compared with stock plastic mounts, the alloy option reduces flex at the knuckle interface and helps preserve toe settings under load during practice sessions. Consider this as a fine-tune component for handling adjustments.
