Kyosho Mini-Z AWD High Shim by 3Racing AWD-13  [AWD-13]

High shim for Mini-Z AWD

This high shim is a dedicated spacer designed for Kyosho Mini-Z AWD platforms, produced by 3Racing under the AWD-13 designation. It functions as a driveline height spacer to alter the vertical position between AWD components and the chassis, enabling finer alignment and reduced binding where small height differences affect gear mesh or shaft angle.

Installation is straightforward: the shim is placed where the drivetrain stack, differential housing, or gearbox interfaces with the chassis mounting points to increase clearance. Ensure fasteners are loosened, fit the shim to seating surfaces, verify alignment before torqueing hardware to factory values, and check driveline rotation for smooth operation after fitting.

Tuning role: use the high shim to correct minor misalignments, reduce unwanted contact, and experiment with driveline geometry during setup sessions. Small thickness changes can influence traction feel and drivetrain smoothness on smooth track surfaces where Mini-Z AWD tolerances are tight.
