ASV GT3 soft blue chassis

The NSR soft chassis for the Aston Martin Vantage GT3: adjusted stiffness, greater flexibility on track

NSR offers its chassis in different hardness levels so that each driver can configure their car according to the circuit, driving style, and race conditions. The NSR1445 chassis corresponds to the soft version, identified in blue, and is specifically designed for the NSR Aston Martin Vantage GT3.

Available hardness scale

NSR produces this chassis in four stiffness levels, each identified by a different colour:

• Soft: blue — greater flexibility, more grip in slow corners and technical circuits.
• Medium: black — balance between stiffness and flexibility, a versatile option for most layouts.
• Hard: white — more stiffness, better response on fast circuits with few tight corners.
• Extralight: yellow — the most flexible option in the range, for very specific configurations.

Function and performance

The stiffness of the chassis directly influences how the weight of the car is distributed and how the wheels maintain contact with the track. A soft chassis like this allows for greater torsion of the assembly, which favours traction on uneven surfaces or in tight corners. It is a common choice on circuits with a lot of technical detail or when looking to improve stability during sudden direction changes.

Compatibility and assembly

This chassis is the original NSR replacement for the Aston Martin Vantage GT3 model from the same brand. If you are preparing or repairing a car of this reference, it is the direct replacement part. As with all NSR chassis, the assembly is precise and does not require additional modifications for installation in the original car.

When to choose the soft chassis?

The blue soft chassis is a good choice when the layout has many slow corners, when the track presents some irregularity, or when the car shows a tendency to oversteer with stiffer chassis. It is also the usual starting point for drivers who prefer a smoother and more predictable driving behaviour.

Frequently asked questions

Which NSR cars is this chassis compatible with?

This chassis is specifically designed for the NSR Aston Martin Vantage GT3. It is not interchangeable with other models from the brand that use different chassis geometries.

What is the practical difference between the soft and medium chassis?

The soft chassis (blue) offers greater torsion and flexibility, resulting in better traction in tight corners. The medium (black) is more neutral and works well on most circuits without additional adjustments. The choice depends on the layout and each driver's style.

Can I use this chassis in club racing?

Yes, as long as your championship regulations allow chassis changes in car preparation. It is a common modification in open or semi-free preparation categories.

Is it necessary to readjust the car's mechanics when changing the chassis?

In general, when changing the hardness of the chassis, it is advisable to check the guide height, tyre support, and rear axle play, as the different flexibility may affect these parameters.

How can I quickly identify the hardness of an NSR chassis?

By colour: blue for soft, black for medium, white for hard, and yellow for extralight. It is a very practical visual system for managing preparation stock.

The NSR1445 is the soft (blue) replacement chassis for the NSR Aston Martin Vantage GT3 slot car. Part of NSR's four-stiffness chassis range — soft (blue), medium (black), hard (white), and extralight (yellow) — it offers increased flex for technical layouts and tight corners. A go-to choice for club racers and hobbyists looking to fine-tune chassis behaviour on their 1:32 scale slot car.
