Polycarbonate Body and Styling

The clear polycarbonate shell is formed for aerodynamic efficiency and reduced mass on the straight. Its transparency invites creative painting and the kit includes clear stickers to help personalise the look while keeping weight low.

VZ Chassis Construction and Benefits

The VZ platform is valued for being compact and light, with reinforced points such as the bumper and rear stay base for added durability during hard runs. Its layout supports common upgrades so racers can tailor handling and reliability.

• Low-friction 620 plastic bearings, moulded in POM, help reduce drivetrain losses.
• Chassis and A parts are made from ABS for toughness and part longevity.
• A standard 3.5:1 gear ratio balances acceleration and top end for general track use.

Tuning and Upgrade Options

Owners can modify performance by swapping motors, trying different tyre compounds, or changing gear ratios to match track layout. The model accepts many official Tamiya accessories and parts for straightforward upgrades.

Assembly and Power Notes

Assembly is approachable for newcomers and rewarding for experienced builders, with snap-fit features and clear instructions. The kit includes a Type 130 motor and requires two AA batteries to run, paired with the 3.5:1 gearing.

The Tamiya 95143 Dual Ridge Jr. (VZ) Japan Cup 2021 edition combines a lightweight polycarbonate body with an adaptable VZ chassis that suits racers focused on tuning and track setup. It is a solid pick for both newcomers and competitive Mini 4WD hobbyists.
