MR-03 Compatible Mini-Z AWD Alignment Shim AWD-13 by 3Racing  [AWD-13]

Technical shim for Mini-Z AWD driveline alignment

The AWD-13 high shim is a purpose-engineered spacer intended for Kyosho Mini-Z AWD layouts to adjust vertical offset between drivetrain components and the chassis. It provides a straightforward method to correct slight misalignment that can create elevated gear mesh stress or shaft angle induced binding.

Installation procedure: identify the junction where the differential housing or gearbox meets the chassis mounting face, then seat the shim on the corresponding interface. Ensure mounting fasteners are loosened during placement, verify that the shim sits flush on contact surfaces, and then torque hardware to manufacturer specifications. After assembly, manually rotate the drivetrain to confirm smooth engagement and absence of binding across the operating range.

Tuning and setup notes: use the AWD-13 to incrementally alter driveline geometry during setup sessions. Small thickness adjustments affect shaft angles and gear mesh, which in precision Mini-Z AWD builds can influence driveline efficiency and on-track behaviour. Perform controlled tests after each change and document settings for repeatable results.
