Mosler EVO4 Blue Kit

The Mosler MT900R evolves: EVO4 chassis with triangular cradle and front adjustment

NSR presents the new edition of the Mosler MT900R under the reference NSR1133AW-B, now with a blue body and, above all, featuring the advanced EVO4 chassis as the main highlight. This update is not cosmetic: it incorporates two structural improvements that change the way the car is prepared and adjusted on the track.

Main features

• EVO4 chassis: the latest generation of NSR chassis, designed for greater selective stiffness and better mass distribution.
• Triangular cradle: motor mounting system that improves the rigidity of the assembly and reduces vibrations, contributing to a cleaner transmission.
• Front axle adjustment: allows for adjusting the front geometry of the car, a key factor for fine-tuning cornering behaviour and adapting it to different track profiles.
• Anglewinder motor: the motor is mounted at an angle relative to the rear axle, a configuration that optimises the centre of gravity and weight distribution, resulting in greater stability at high speeds.
• Blue finish: body in blue colour, a differentiated edition within NSR's Mosler range.
• Kit format: supplied for assembly, allowing for customisation of the build and preparation from scratch.

The EVO4 chassis: practical benefits

The NSR EVO4 chassis is a direct evolution of the brand's previous chassis, designed for enthusiasts who want to take their tuning a step further. The triangular cradle secures the motor more solidly than conventional systems, reducing play and traction loss. Meanwhile, the front axle adjustment opens the door to height and geometry adjustments that previously required more invasive modifications, allowing the car to be adapted to fast, technical, or mixed circuits without compromising the integrity of the chassis.

Behaviour and performance

The anglewinder configuration positions the motor at an intermediate angle between the sidewinder (parallel to the rear axle) and the inline (perpendicular), combining the best of both worlds: a low centre of gravity —similar to inline— with a compact transmission. The result is a car that is stable on straights and has good grip in tight corners, especially when the front adjustment offered by the EVO4 is well managed.

Ideal for…

• Enthusiasts who build and prepare their own cars and value the possibility of fine adjustment.
• Club competitors looking for a modern chassis with real tuning potential.
• Collectors of NSR's Mosler range who want to complete the series with this blue edition.

Considerations

As it is a kit, the car requires assembly. NSR facilitates the process with clear instructions and the usual compatibility of its spare parts and accessories, allowing for easy replacement or upgrading of components once assembled. It is advisable to check that all front axle adjustments are securely fixed before the first run.

Frequently asked questions

What is the difference between the EVO4 chassis and previous NSR chassis?

The EVO4 incorporates the triangular cradle for the motor and front axle adjustment, two elements that previous chassis did not include as standard. This expands the tuning possibilities without the need for additional parts.

What exactly is the triangular cradle?

It is the motor mounting system to the chassis. The triangular geometry provides a more rigid and stable fixation than conventional supports, reducing vibrations and improving transmission efficiency.

What is the purpose of the front axle adjustment?

It allows for modifying the geometry and height of the front axle of the car, which directly influences cornering behaviour. It is especially useful for adapting the car to different types of circuits or tracks.

Is it compatible with Scalextric or Ninco tracks?

Yes. Like the rest of the NSR range, this Mosler is compatible with universal track systems, meaning it works with Scalextric and Ninco tracks, among others.

Are all necessary components for assembly included?

As it is a kit, it includes the main elements for assembly. We recommend checking the specific contents of the kit before assembly to see what additional accessories may be needed based on your usual setup.

Can I replace the motor with another from the NSR range?

The EVO4 chassis is designed within the NSR ecosystem, so compatibility with other motors from the brand is one of its usual advantages. Check the specifications of the specific motor to confirm compatibility before making the change.

The NSR Mosler EVO4 Kit in blue (ref. NSR1133AW-B) is a high-performance 1/32 slot car kit featuring the advanced EVO4 chassis, triangular motor mount and front axle adjustment. Equipped with an anglewinder motor configuration for improved weight distribution and low centre of gravity, it is designed for club racing enthusiasts and experienced builders who demand precise setup options. Compatible with universal slot car track systems including Scalextric and Ninco. Available at Ministry of Hobby.
