Fiat 500 soft chassis

The NSR Soft chassis for the Fiat 500: fine-tuning for competitive advantage

When we talk about serious slot preparation, the choice of chassis makes a real difference on the track. NSR knows this well, which is why it offers three hardness options for its Fiat 500 that allow the chassis flex to be adapted to the characteristics of each circuit and the preferences of each driver.

Main features

• Reference: NSR1355
• Compatible model: NSR Fiat 500
• Hardness: Soft
• Identifying colour: Blue

The NSR colour code facilitates quick identification on the workbench: the soft chassis (Soft) is blue, the medium is black, and the hard is white. A simple convention that avoids confusion when working with multiple chassis sets at once.

What does a Soft chassis offer?

A soft chassis provides greater lateral flex, allowing the car to better adapt to the irregularities of the track and improve tyre contact with the surface. This typically translates to increased traction on circuits with bumps or pronounced joints, and smoother, more predictable handling on slow layouts with many curves.

Conversely, on very technical and fast tracks with good grip, a medium or hard chassis may be more suitable. The key is to test and compare: that’s why having all three types available is a real advantage for any driver looking to get the most out of their NSR Fiat 500.

Assembly and preparation

This chassis is manufactured by NSR and is designed to fit directly into the NSR Fiat 500, with no modifications. The replacement process is straightforward: it allows for the exchange of all mechanical groups from the original car — motor, rear axle, guide, braid — in just a few minutes, making it an ideal component for tuning between sessions or heats in a championship.

Ideal for…

• Club drivers looking to fine-tune the setup of the NSR Fiat 500 according to the circuit.
• Enthusiasts wanting to explore how chassis hardness influences car behaviour.
• Preparers working with multiple chassis sets to quickly adapt to different track conditions.

Considerations

This chassis is exclusively compatible with the NSR Fiat 500. Before purchasing, ensure that your car corresponds to this specific model from the brand. NSR maintains a good stock of spare parts for its vehicles, facilitating long-term preparation and maintenance.

Frequently asked questions

What is the difference between the NSR Soft, Medium, and Hard chassis?

The difference lies in the rigidity of the material. The Soft (blue) is the most flexible, the Medium (black) offers an intermediate balance, and the Hard (white) is the most rigid. Each hardness responds differently depending on the layout and grip conditions of the track.

Is this chassis compatible with other NSR models?

No. This chassis is specifically designed for the NSR Fiat 500. Each model has its own chassis with unique geometry and measurements.

Do I need to modify anything to install it?

No modifications are necessary. The chassis is designed as a direct replacement and accepts all mechanical components from the original NSR Fiat 500.

When is it advisable to use the Soft chassis over the Hard?

The Soft typically performs better on tracks with more irregularities or on layouts with slow curves where greater traction is sought. The Hard tends to perform better on fast and very technical circuits with good overall grip. It is recommended to try both and compare lap times.

The NSR1355 is a soft chassis (blue) for the NSR Fiat 500 slot car, designed to improve traction and handling on club tracks. Part of NSR's three-stiffness chassis range — soft (blue), medium (black) and hard (white) — it allows precise setup tuning for different track conditions. A direct-fit replacement that requires no modifications, compatible with all standard mechanical components of the NSR Fiat 500.
