CNC Plastic Front Wheels 3/32 13mm 0.3g

CNC Precision and Minimum Weight for Your Slot Car Front End

The NSR5025 wheels are front wheels made from CNC machined plastic by NSR. With a diameter of 13 mm, a 3/32 axle, and a weight of just 0.3 g per unit, they are designed for those looking to reduce unsprung mass on the front axle and gain responsiveness and agility on track.

Main Features

• Material: CNC machined plastic, with high dimensional accuracy.
• Diameter: 13 mm.
• Compatible axle: 3/32 inches.
• Weight: 0.3 g per wheel.
• Position: front.
• Reference: NSR5025.

Function and Performance

The front end of a slot car primarily serves a steering function: it does not transmit traction but directly influences cornering stability and the lateral movement of the guide. An excessively heavy front wheel can create unwanted inertia and affect chassis behaviour. At only 0.3 g, these NSR wheels allow the front end to remain as neutral as possible, enabling tuning efforts to focus where it really matters: the rear end and load distribution.

CNC machining ensures very tight concentricity, resulting in uniform rolling without parasitic vibrations. This is particularly relevant in competition setups where any imbalance is noticeable in lap times and high-speed stability.

Compatibility and Installation

Designed for a 3/32 inch axle, the most widely used standard in the NSR product range. They are suitable for use with the same brand's front tyres, following the corresponding diameter recommendations. Before installation, it is advisable to verify that the outer diameter of 13 mm is appropriate for the body and chassis being prepared, especially in setups with limited space in the wheel arches.

Preparation and Common Mistakes

When installing front wheels on a competition slot car, it is common to neglect the balancing of the wheel-tyre assembly. Although the weight is minimal, an off-centre tyre or a wheel with impurities in the axle fit can introduce a micro-imbalance that amplifies at high RPM. We recommend always checking the axle fit with a caliper and ensuring that the tyre is perfectly adhered and concentric before the first run.

Ideal for…

Preparers and drivers who focus on detail in their competition setups with NSR cars, and who seek to optimise every component of the front end for improved lap consistency.

Frequently Asked Questions

How many wheels are included in the NSR5025 pack?

The available information does not specify the exact number of units per pack. We recommend checking the product description in-store or contacting us to confirm before placing your order.

What axle are these wheels for?

They are compatible with a 3/32 inch axle, the standard size in most NSR setups.

Can I use them with any NSR front tyre?

In principle, yes, as long as the tyre is of the appropriate diameter for a 13 mm wheel. Check the NSR compatibility chart to ensure you choose the correct tyre.

What advantage does CNC machining have in a plastic wheel?

CNC machining allows for very tight tolerances in diameter and axle hole, ensuring superior concentricity compared to conventionally injection-moulded wheels. The result is cleaner rolling and no vibrations.

Are they suitable for club track use or just for practice?

They are preparation components commonly used in club competition. Their low weight and precision make them suitable for any level of demand.
