AWD Mini-Z bearing tune

The AWD-20 bearing set offers a compact drivetrain upgrade for Kyosho Mini-Z AWD layouts, replacing worn running surfaces to promote smoother shaft rotation and steadier power delivery during practice sessions.

Compatibility is focused on MR-03 AWD style components used in Mini-Z AWD configurations. These bearings act as replacements for plain bushings or degraded parts where sizes align; always verify dimensions before installing.

Installation advice: press bearings into gearbox housings, wheel hubs and rotating shafts as required, confirming each bearing spins freely before reassembly. Routine checks and a light lubricant will help maintain rolling performance.

Used as a tuning refresh, AWD-20 reduces drivetrain drag so throttle response feels sharper on carpet and other indoor surfaces, making minor efficiency gains without more invasive modifications.

Do these bearings suit MR-03 AWD mini cars?

They are made for MR-03 AWD style drivetrains, but check the bearing dimensions against your chassis to ensure a direct fit before pressing them in.

How often should I service them?

Inspect periodically for debris and reapply a small amount of light oil as needed; frequent heavy lubrication is unnecessary and slows the drivetrain.

Will bearings affect straight-line speed?

Reducing internal friction can improve acceleration and top speed slightly, but gains are most noticeable in throttle response and consistency rather than dramatic speed jumps.
