Mosler EVO5 Soft chassis

The EVO5 Soft chassis: the foundation that makes a difference in the Mosler MT900R

Within the NSR tuning ecosystem, the chassis is much more than a structural support: it is the element that defines how the car behaves on track. The EVO5 Soft Chassis (ref. NSR1449) is specifically designed for the Mosler MT900R and represents the most flexible variant within NSR's EVO5 line.

Function and performance

The Soft version of a slot chassis implies a material with greater torsion capacity and absorption of track irregularities. This translates into more consistent contact of the four support points with the rail, improving stability and traction on circuits with small imperfections or on tracks with fast, consecutive curves.

Compared to the standard or hard version, the EVO5 Soft tends to offer a smoother and more predictable driving experience, especially beneficial in technical track configurations or when consistency in lap times is sought over outright top speed.

Compatibility

This chassis is exclusively compatible with the Mosler MT900R from NSR. As it is a spare part from the same brand, the fit with the body and original mechanical components of the model is direct, with no need for adaptations.

Assembly and preparation

Changing the chassis on an NSR car is a straightforward operation for any enthusiast with basic slot preparation experience. It is enough to transfer the motor, rear axle, guide, braids, and wheels from the original chassis to the new EVO5 Soft. It is a quick way to test different configurations without modifying the rest of the mechanical train.

If you are going to use it in club competition, it is advisable to check the regulations before mounting: some championships specify the type of chassis allowed to ensure equality among participants.

Ideal for…

• Drivers looking to improve the consistency and stability of the Mosler MT900R on track.
• Enthusiasts who want to experiment with different chassis configurations without changing the rest of the components.
• Club competitors looking to optimise the car on circuits with uneven surfaces or many consecutive curves.

Aspects to consider

NSR offers different chassis variants (Soft, standard, etc.) for its models, and the correct choice depends on the type of track, the motor used, and the driving style. If you have doubts about which one best suits your setup, Ministry of Hobby can guide you.

Frequently asked questions

What is the difference between the EVO5 Soft chassis and the standard one?

The Soft version uses a material with greater flexing capacity, allowing the chassis to better absorb track irregularities and maintain more uniform contact with the rail. The result is a more stable and predictable driving experience, although with slightly less rigidity than the standard version.

Is it compatible with other NSR models besides the Mosler MT900R?

No. The NSR1449 chassis is specifically designed for the Mosler MT900R. Using a chassis from another model may cause incompatibilities with the body and mechanical mounts.

Do I need special tools to assemble this chassis?

No specific tools are required beyond the usual ones for slot preparation: precision screwdrivers and, optionally, some Allen keys depending on the motor assembly. It is an operation within the reach of any enthusiast with basic experience.

Can I use this chassis in club competition?

It depends on the regulations of each championship. Some organisers allow the chassis to be changed freely; others require the car to maintain the original factory chassis. Check the rules of your series before modifying the car.

Does it come with any additional components or is it just the chassis?

The NSR1449 includes only the EVO5 Soft chassis. The rest of the components (motor, axle, guide, braids, wheels) are transferred from the original car set.

The NSR1449 is the EVO5 Soft chassis designed specifically for the NSR Mosler MT900R slot car. This flexible chassis version improves traction and stability on technical tracks, making it a key upgrade for club racing and advanced slot car tuning.
