EVO 2 red extra hard inline motor mount

Stiffness where it matters most: the extra hard inline motor mount EVO 2 from NSR for the Mosler Evo 3

The reference NSR1244 is the motor mount in inline configuration — that is, with the motor positioned inline with the rear axle, longitudinally — in its EVO 2 version and extra hard stiffness, identified by the red colour. NSR specifically designs it for the Mosler Evo 3 chassis, ensuring a precise fit and correct geometry from the very beginning.

Main features

• Inline configuration: the motor is housed in a longitudinal position relative to the rear axle, which helps lower the car's centre of gravity and improves cornering stability.
• Extra hard stiffness (red): NSR colour codes the stiffness of its mounts. Red corresponds to the most rigid version in the range, designed for drivers seeking maximum firmness in motor retention and minimal deformation under load.
• EVO 2 version: revised generation of the mount, with improvements in mounting geometry compared to previous versions.
• Specific compatibility: designed for the NSR Mosler Evo 3 chassis.

Function and performance

The motor mount is a component that is often underestimated, but it has a direct influence on the car's behaviour. A stiffer mount reduces the micro-deformations that occur during acceleration and braking, resulting in a more linear and predictable response. The extra hard version is particularly valued on technical circuits and in competitive setups where chassis tuning is pushed to the limit.

In inline configuration, the longitudinal position of the motor allows for a more balanced weight distribution along the car's central axis, favouring stability in fast corners and more consistent traction during acceleration segments.

Installation and preparation

The installation of this mount is straightforward onto the Mosler Evo 3 chassis, with no need for additional modifications. It is advisable to check the alignment of the pinion with the crown gear before tightening the fixing points definitively, to ensure smooth engagement without unnecessary play. If changing from one stiffness to another, it is also recommended to check the tension of the braids and the pressure of the guide, as the rigidity of the assembly can affect the overall behaviour of the drivetrain.

Recommended applications

This mount is aimed at racers who are already familiar with their Mosler Evo 3 chassis and want to fine-tune the behaviour seeking greater firmness. The extra hard stiffness is a good choice on wooden tracks with medium to high radius corners, where stability takes precedence over the absorption of irregularities. On tracks with more irregularities or very tight corners, it is advisable to consider lower stiffness versions before deciding.

Common mistakes

• Installing a mount with inappropriate stiffness for the type of track: harder does not always mean faster.
• Not checking the alignment of the pinion after installation, which can cause premature wear or noise in the drivetrain.
• Confusing inline configuration with sidewinder: in inline, the motor is longitudinal (in line with the rear axle); in sidewinder, it is transversal (parallel to the rear axle).

Frequently asked questions

Which chassis is the NSR1244 compatible with?

According to the information provided by NSR, this mount is specifically designed for the Mosler Evo 3 chassis. Before installing it on another chassis, consult the NSR compatibility chart or contact us.

What does "extra hard" mean in NSR mounts?

NSR differentiates its mounts by material stiffness, colour-coded. Red corresponds to the extra hard version, the most rigid in the range. It provides greater firmness in motor retention and less deformation under load, ideal for competition or drivers seeking maximum consistency in the car's response.

What is the difference between inline, sidewinder, and anglewinder?

These are three distinct motor configurations in slot racing: inline positions the motor longitudinally (in line with the rear axle), lowering the centre of gravity; sidewinder places the motor transversely (parallel to the rear axle); and anglewinder positions it at an angle relative to the rear axle. Each has its advantages depending on the type of track and the desired setup.

Can I combine mounts of different stiffness on the same chassis?

In general, NSR chassis use a single motor mount, so it is not common to combine stiffnesses. However, you can try different stiffnesses depending on the circuit and race conditions to find the optimal balance.

Do I need special tools for installation?

No. The installation is straightforward and compatible with standard slot preparation tools. However, it is advisable to use an alignment checker to confirm that the pinion and crown gear engage correctly after installation.

The NSR1244 is an extra hard inline motor mount (EVO 2 version, red) for the NSR Mosler Evo 3 chassis. Designed for slot car racing, this rigid motor pod ensures precise motor positioning in a longitudinal inline configuration, reducing flex under load and delivering more consistent power transfer. A key upgrade for competitive slot car enthusiasts seeking improved chassis performance and lap time consistency on wooden or routed tracks.
