ASV GT3 yellow extralight chassis

The lightest chassis from NSR for the Aston Martin Vantage GT3

The NSR Extralight yellow ASV GT3 Chassis (ref. NSR1447) is the pinnacle of the replacement chassis range that NSR offers for its Aston Martin Vantage GT3 body. Identified by its distinctive yellow colour, the Extralight is aimed at drivers who want to minimise the total weight of the car and fine-tune their setup for club or championship racing.

NSR hardness range: understand the difference

NSR offers its chassis for the ASV GT3 in four versions, each with different behaviour on the track:

• Soft (blue): greater flexibility, ideal for tracks with high grip or plastic surfaces where the chassis needs to work by absorbing irregularities.
• Medium (black): the balance between traction and stability, the reference option for most setups.
• Hard (red): less flex, more rigidity; suitable for technical circuits with high speed and very smooth surfaces.
• Extralight (yellow): the lightest in the range. Reduces the total weight of the assembly to improve acceleration and response, especially on tracks with good grip conditions.

The choice between one hardness and another depends on the type of track, the installed motor, and the driving style. The yellow Extralight is often the choice of drivers who already master their car's setup and seek that extra margin provided by the lowest possible weight.

Function and performance

A chassis in good condition is the foundation of any competitive slot car. Over time and with intensive track use, chassis can lose rigidity, deform from impacts, or simply become misaligned with the original geometry. Replacing it with a new unit —and choosing the right hardness— is one of the most effective interventions in slot car preparation.

The Extralight, by reducing weight, favours a more responsive throttle and can make a difference in categories where regulations limit other preparation variables.

Compatibility

This chassis is specifically designed for NSR cars with the Aston Martin Vantage GT3 body. Before purchasing, ensure that your model corresponds to this platform to guarantee a correct fit of all components: guide, braids, motor, axles, and wheels.

Assembly and preparation

The replacement process follows the same logic as any NSR chassis: disassemble the complete assembly, transfer the mechanical components to the new chassis, and check the alignment of axles and the height of the guide before returning to the track. NSR has an extensive catalogue of spare parts —motors, crowns, pinions, axles, braids— that facilitate total car customisation.

Frequently asked questions

What does Extralight mean in NSR chassis?

Extralight indicates that the chassis is made from a material or process that reduces its weight compared to the rest of the range. It is the lightest version available, identified by the yellow colour.

What type of track is the Extralight chassis most suitable for?

It performs better on tracks with good grip conditions, where lightness translates directly into acceleration and response without the lack of mass penalising corner stability.

Can I mount this chassis with any NSR motor?

The chassis is compatible with the NSR platform of the Aston Martin Vantage GT3. The choice of motor depends on your category and preferences, but the chassis itself does not limit the motorisation as long as it is suitable for this platform.

Is it complicated to replace the chassis of an NSR car?

Not particularly. With basic slot preparation tools and some practice, the replacement is accessible even for hobbyists with average experience. NSR facilitates the process with well-documented and easily locatable spare parts.

What is the difference between the soft (blue) chassis and the Extralight (yellow)?

The soft prioritises flexibility to absorb track imperfections. The Extralight prioritises low weight to improve response and acceleration. They are distinct concepts and the choice depends on track conditions and preparation style.

The NSR1447 Extralight yellow chassis is designed for the Aston Martin Vantage GT3 slot car body by NSR. As the lightest option in the NSR chassis range, it is the go-to choice for competitive slot racing enthusiasts looking to reduce overall car weight and improve throttle response. Compatible with NSR ASV GT3 platform, it integrates seamlessly with standard NSR components including motors, axles, gears and braids. Ideal for club racing and serious hobbyists seeking performance-oriented setup options.
