HYPERCAR EXTRAHARD GREEN CHASSIS

The NSR ExtraHard green chassis, designed for those who do not tolerate flex in competition

Within the NSR spare parts catalogue for the Hypercar platform, the ExtraHard green chassis (ref. NSR1635) occupies a special place: it is the stiffest option in the range and is aimed at track conditions with a high level of grip, where a chassis that is too flexible can work against the driver. NSR identifies its chassis by colours according to the degree of stiffness, and green corresponds to the ExtraHard variant, the firmest in the family.

Function and performance

The stiffness of a plastic chassis directly influences how the weight of the car is distributed over the four contact points. A soft chassis allows the vehicle to adapt to small irregularities in the track, which can improve tyre contact on circuits with low grip. However, on surfaces with a lot of rubber laid down or with high adhesion, that same flexibility generates unpredictable behaviour: the car sways excessively, loses consistency in braking, and cornering becomes irregular lap after lap.

The ExtraHard green chassis minimises longitudinal and transverse torsion, providing a stable platform on which motors, axles, and transmission work more efficiently. The result is a more direct response to the controls, greater consistency in behaviour, and a reduction in parasitic vibrations that consume energy without any benefit in softer chassis.

Compatibility

This chassis is specifically designed for the NSR Hypercar models in 1/32 scale. It maintains full compatibility with the rest of the components in the range: axles, motors, crown gears, pinions, and bodies specific to this family. The assembly is direct, with no additional modifications required.

Assembly and preparation

Replacing the original chassis with this ExtraHard version does not require special tools. Simply disassemble the body, remove the mechanical components from the current chassis, and transfer them to the new piece while respecting the axle clearance adjustments. It is advisable to check the parallelism of the axles after assembly and ensure that the guide operates with freedom of movement, as the greater stiffness of the chassis makes any mechanical tension more noticeable than in softer versions.

What type of driver and circuit is this chassis for?

The ExtraHard green chassis is the usual choice for drivers competing on circuits with a lot of accumulated grip, very adhesive surfaces, or conditions where precision in the racing line takes precedence over the ability to absorb irregularities. If your usual track has little rubber or is wooden with a low friction coefficient, a softer version may adapt better. Conversely, if you train or compete on well-run plastic circuits or with high-grip mats, the ExtraHard green will provide the consistency you seek.

Common mistakes

• Using the stiffest chassis in any condition: the ExtraHard stiffness is not universally better. On tracks with low grip, it can cause the car to lose contact with the rear tyres and skid easily. Choose the hardness based on the circuit.
• Not checking the axles after assembly: being the most rigid chassis, any tension in the axles directly affects performance. An axle with friction in a rigid chassis impacts performance more than in a soft one.
• Confusing the green colour with other variants in the range: NSR uses a colour scale to identify the stiffness of its chassis. Ensure that the colour you choose corresponds to the desired hardness for your setup.

Frequently asked questions

What is the difference between the different colours of NSR chassis for Hypercar?

NSR uses a colour code to identify the stiffness of its plastic chassis. Each colour corresponds to a different degree of hardness: lighter or softer colours usually indicate greater flexibility, while the ExtraHard green represents the stiffest variant in the range. This allows the driver to adjust the car's setup according to track conditions.

Which NSR Hypercar models is this chassis compatible with?

The NSR1635 is designed for the NSR Hypercar platform in 1/32 scale. If you have doubts about compatibility with a specific model, check the reference of your car's original chassis before placing your order.

Can I use this chassis on a low-grip track?

It is not the most advisable. The ExtraHard chassis is designed for high-grip conditions. On tracks with low adhesion, a softer chassis distributes weight better and maintains tyre contact, offering a more balanced performance.

Is it necessary to modify any components to mount this chassis?

No. The assembly is direct and compatible with the standard components of the NSR Hypercar range. However, it is advisable to check the parallelism of the axles and the freedom of movement of the guide after assembly, especially when switching to a stiffer variant.

What advantage does a stiffer chassis provide over the original?

In high-grip conditions, stiffness prevents the car from swaying excessively, reduces parasitic vibrations, and improves consistency lap after lap. The result is more predictable behaviour and a more direct response to the controls, making it easier to brake late and maintain precise racing lines.
