Formula 1 22 Extraduro green chassis NSR

The extra-hard chassis that makes a difference in the NSR Formula 1 22

The NSR1623 is the extra-hard green chassis specifically designed for the NSR Formula 1 22. Identified by its green colour, this chassis offers superior stiffness within the range of replacement chassis that NSR provides for this model, allowing the driver to adjust the car's behaviour according to the type of track and their driving style.

Function and performance

In the world of slot racing, the chassis is the soul of the car: it conditions flexibility, power transmission, and response to changes in direction. NSR codes its chassis by colours according to their stiffness level, and the extra-hard green is the option designed for those who need maximum structural rigidity. A harder chassis reduces the torsion of the assembly, resulting in more direct handling, with less tendency to "push" in corners and a more immediate response to the controller inputs.

This behaviour is particularly advantageous on tracks with fast, wide-radius corners, where stability is paramount over manoeuvrability. On very technical circuits or those with many chicanes, the choice of stiffness will depend on the driver's personal style and the type of grip available on the track.

Compatibility

This chassis is designed exclusively for the NSR Formula 1 22. It is not interchangeable with other models in the NSR range without first verifying geometric compatibility. Before making any replacement, we recommend checking that the chassis fits correctly with the body, motor, and axles of your assembly.

Assembly and preparation

Replacing the chassis is one of the most common preparation operations among slot racing enthusiasts. When changing the chassis, it is advisable to check the condition of the axles, guide, braids, and motor before reassembling the car, taking advantage of the disassembly to perform a general review of the assembly. NSR, as a benchmark brand in spare parts and slot preparation, facilitates this process with precisely fitting parts that do not require additional modifications.

Ideal for…

• Club racers who want to experiment with different stiffness levels to optimise the car according to the track.
• Enthusiasts who have suffered damage to the original chassis and are looking for a direct replacement.
• Preparers who assemble different configurations of the Formula 1 22 for various championships.

Aspects to consider

The ideal stiffness level of the chassis depends on multiple factors: the type of track, the rubber used, the weight of the assembly, and environmental conditions. An extra-hard chassis is not "better" in absolute terms, but rather the right tool for certain conditions. If you are starting to explore the preparation of the Formula 1 22, we recommend comparing the behaviour with other stiffness levels available in the NSR range to find the optimal point.

Frequently asked questions

What does it mean for the chassis to be "extra-hard"?

NSR distinguishes its chassis by degrees of flexibility, coded by colours. The extra-hard (green) is the most rigid, which reduces chassis torsion during driving and provides a more direct and stable response, especially in fast corners.

Is this chassis compatible with other NSR models apart from the Formula 1 22?

Not necessarily. This chassis is designed for the NSR Formula 1 22. The geometry varies between models, so compatibility with other cars in the range should not be assumed without prior verification.

Can I install this chassis myself or do I need a specialised workshop?

Replacing the chassis on an NSR car is within the reach of any enthusiast with basic slot preparation experience. The parts are designed for a precise fit. However, if it is your first time, it is advisable to take the necessary time and check the condition of all components during the process.

What is the difference between the green chassis and other NSR colours?

NSR uses a colour code to indicate the stiffness level of its chassis: the higher the stiffness, the greater the rigidity and less torsion. The green corresponds to the extra-hard category. Other colours represent intermediate or softer stiffness levels, with different behaviours on track.

Does this chassis improve performance compared to the original?

It depends on the context. If the original chassis was of a different stiffness and the driver needs more stability, the extra-hard may represent a notable improvement. If track conditions favour more flexibility, the result may be the opposite. The key is to adjust the stiffness to the actual competition conditions.

The NSR1623 is the extra-hard green chassis for the NSR Formula 1 22 slot car, offering maximum structural rigidity for fast and technical track layouts. A key tuning part for club racers and slot car enthusiasts looking to fine-tune chassis flex and improve lap consistency. Compatible exclusively with the NSR Formula 1 22 body and mechanical kit, this replacement chassis is a must-have spare for competitive 1/32 slot racing.
