CORVETTE C7R EXTRALIGHT YELLOW CHASSIS

The NSR Extralight Yellow Chassis for the Corvette C7R: fewer grams, more precision in every corner

The NSR1491 is the yellow Extralight chassis specifically designed for the NSR Corvette C7R. Made from low-density engineering plastic — the key to the Extralight concept — it allows for a reduction in the overall weight of the car without compromising structural rigidity or suspension geometry. In slot racing, every tenth of a gram counts, and this chassis is designed precisely for enthusiasts who want to maximise the potential of their Corvette C7R.

Features and Highlights

• Extralight Concept: low-density plastic that reduces the chassis weight compared to NSR's standard versions, improving acceleration and cornering response.
• Yellow Colour: facilitates quick visual identification within the NSR Extralight range and adds a distinctive touch on the preparation bench.
• Specific Compatibility: designed for the NSR Corvette C7R, respecting all mounting points, axle geometry, and motor position specific to this model.
• NSR Precision: maintains the millimetric tolerance standards that characterise the brand, ensuring a clean assembly with no unnecessary play.

Function and Performance

Replacing the original chassis with an Extralight chassis is one of the most effective and clean modifications that can be made to a competitive slot car. By lowering the total weight, the car gains agility: acceleration from a standstill improves, braking becomes sharper, and response in chicanes is refined. The yellow colour is not just an aesthetic detail; within the NSR Extralight range, the colour code allows for quick identification of the version installed on the car, which is very practical when working with multiple chassis sets for different track configurations.

Compatibility and Assembly

This chassis is designed exclusively for the NSR Corvette C7R. Before installation, it is advisable to verify that the reference of the base car corresponds to this model, as NSR has specific chassis for each body in its catalogue. The assembly follows the usual process for NSR chassis: disassembly of the body, transfer of the motor-axle group and guide, and readjustment of braids. No additional modifications are required if the other components are original NSR for this model.

Ideal for…

• Club competitors looking to reduce the weight of their Corvette C7R without resorting to complex structural modifications.
• Enthusiasts preparing cars for championships with modification limits, where the Extralight chassis fits within the categories that allow its use.
• Preparers who want to have a second chassis assembled and ready to change in the pits between heats.

Considerations

As this is a lower density chassis, it is important to check the torque of the screws during assembly: excessive force can compromise the thread. Additionally, if the regulations of the championship you are participating in specifically regulate the type of chassis allowed, consult the rules before installing this part. NSR offers a wide range of spare parts and complementary accessories that allow for progressive car configuration.

Frequently Asked Questions

Is this chassis compatible with all NSR Corvette C7R models?

It is designed for the NSR Corvette C7R. If you have doubts about the exact compatibility with your specific reference, we recommend checking before making the change, as NSR may have variants of the model with slight differences in assembly.

How much weight is saved with the Extralight chassis compared to the standard?

NSR does not officially publish the exact weight difference between versions, but the Extralight concept is aimed at significantly reducing the overall weight of the assembly. The perceptible improvement on track also depends on the other installed components.

Does the yellow colour affect performance?

No. The colour is an identification code within the NSR Extralight range and does not influence the mechanical properties or weight of the chassis.

Do I need special tools to assemble this chassis?

The assembly is done with the same standard slot preparation tools: precision screwdrivers, axle wrenches, and alignment tools if you want to fine-tune the geometry after assembly. No special tooling is required.

Can I use this chassis on universal track (Scalextric, Ninco)?

The chassis itself is compatible with any track surface, as long as the car has the appropriate guide for the type of track. The choice of chassis is not conditioned by the track system you use.

Does this chassis include a motor, axle, or guide?

No. It is solely the chassis (the structural piece). The motor, axle, braids, and guide are transferred from the original assembly or purchased separately according to the desired configuration.
