NSR Front Wheels: Lightweight and CNC Precision for the Front End

The NSR5023 wheels are the reference option when looking to reduce unsprung mass on the front axle without compromising the dimensional precision that only CNC machining can provide. Made from high-consistency plastic, they combine a weight of just 0.3 g with a precise fit for a 3/32 axle and a diameter of 16 mm, key values in serious slot car preparation.

Main Features

• CNC Manufacturing: precision machining that guarantees optimal concentricity and balance.
• Diameter: 16 mm — specific measurement for the front axle in competition configurations.
• Compatible Axle: 3/32 (2.38 mm), the most widely used standard in 1/32 scale.
• Weight: 0.3 g per wheel — minimal rotational inertia on the front axle.
• Material: engineering plastic, lightweight and sufficiently rigid to maintain shape under load.

Function and Performance

On the front axle of a slot car, the wheel serves an essential function: to support the tyre and faithfully transmit any variation in trajectory. Reducing weight at this point decreases gyroscopic inertia, improves response in corners, and contributes to a more balanced weight distribution. CNC machining ensures that the centre of the axle hole and the outer perimeter are perfectly concentric, preventing vibrations that degrade tyre grip.

Compatibility and Installation

These wheels are designed for 3/32 axles, the usual diameter in NSR chassis and in much of the 1/32 catalogue from brands like Slot.it or Scaleauto. Before installation, it is advisable to check that the diameter of the receiving chassis axle matches this measurement. The fit should be firm but not forced; if the axle has play, a small amount of low-retention adhesive can secure the wheel without damaging it upon removal.

When changing front wheels, it is also recommended to check the condition of the tyres and, if using wheels of a different diameter compared to the rear, to recalculate the chassis height to maintain the correct flatness on the track.

Ideal for…

• Preparers and club drivers looking to minimise rotational weight on the front axle.
• Competition configurations where every tenth of a gram in rotating mass influences performance.
• Replacement of worn or deformed wheels on NSR cars and other chassis compatible with 3/32 axles.

Considerations

As these are plastic wheels, their use is intended for the front axle — where no motor torque is applied — as the material's rigidity is completely sufficient at this point. They are not recommended for the rear axle in high-power configurations, where aluminium wheels offer greater resistance to deformation.

Frequently Asked Questions

How many wheels are included in the package?

The available information does not specify the number of units per package. We recommend checking directly with our team before placing an order.

Are they compatible with chassis from other brands besides NSR?

Yes, as long as the chassis has a front axle of 3/32 (2.38 mm). This measurement is standard in many 1/32 chassis on the market, so compatibility is broad. Check the diameter of your axle before installing them.

Can I combine them with any NSR front tyre of 16 mm?

In principle, yes: the 16 mm diameter is designed to accept NSR front tyres of that size. Check the width of the wheel against the width of the chosen tyre to ensure a proper fit.

What advantage does CNC machining offer over an injection-moulded wheel?

CNC guarantees virtually perfect concentricity between the axle hole and the outer perimeter. An eccentric wheel causes vibrations that reduce tyre grip and, on technical tracks, translates into lost time per lap. With CNC wheels, that factor is eliminated.

Is it necessary to balance the wheels after installation?

Given their low weight (0.3 g) and CNC manufacturing, pre-installation balancing is usually not necessary. However, in top-level competitive setups, some drivers perform a runout check with a verification tool in case there are minimal residual variations.
