Audi R 18 Extra Soft Yellow chassis

The Extra Soft Chassis from NSR for the Audi R18: Fine-tune Flexibility and Gain Traction

The NSR1410 is the specific chassis for the NSR Audi R18 body, manufactured in the Extra Soft hardness and identified by its yellow colour. Within the range of interchangeable chassis from NSR, the colour coding allows for quick identification of the appropriate hardness without confusion in the spare parts drawer: yellow always corresponds to the softest version in the catalogue.

Function and Performance

The hardness of the chassis directly influences how the car distributes its weight in corners and how the wheels maintain contact with the track. An Extra Soft chassis allows for greater flex of the assembly, resulting in:

• Increased traction on circuits with uneven surfaces or with many linked direction changes.
• A more forgiving setup, especially useful on tracks with imperfections where a rigid chassis would penalise traction.
• A smoother driving feel in slow and medium corners.

NSR manufactures its chassis from high-engineering plastic, with geometry specifically developed for each body in its catalogue. The NSR1410 respects the mounting points and wheelbase of the Audi R18, ensuring a direct replacement without the need for additional modifications.

Compatibility

This chassis is designed exclusively for the Audi R18 bodies in the NSR catalogue. It is not interchangeable with other models from the brand or with bodies from third-party manufacturers. If you have doubts about which chassis reference corresponds to your car, consult the equivalence table in the NSR catalogue or contact us.

Assembly and Preparation

Replacing the chassis is a common operation in the preparation process of a competition slot car. Some tips to get the most out of the NSR1410:

• Take advantage of the chassis change to check the condition of the bearings, rear axle, and guide.
• Compare the car's behaviour with different chassis hardnesses on your usual circuit before deciding on a final configuration.
• The Extra Soft usually performs better on wooden circuits or on tracks with low base grip; on very aggressive surfaces, an intermediate hardness may offer better balance.
• Ensure that all mounting screws are tightened correctly: excessive tension negates part of the effect of the chassis flexibility.

Common Mistakes

• Confusing hardness by colour: NSR codes its chassis by colour according to hardness; yellow is Extra Soft. Always verify the reference before ordering.
• Fitting an inappropriate hardness chassis for the track: an Extra Soft on a very aggressive plastic track may be too permissive and hinder car control.
• Not checking the mechanics when changing the chassis: the change is the ideal time for a complete setup of the entire underside of the car.

Frequently Asked Questions

What is the difference between the different NSR chassis hardnesses?

NSR offers several hardnesses in its chassis range, identified by colours. A lower hardness (Extra Soft, yellow) allows for more flex and more traction under certain conditions; a higher hardness provides more stiffness and precision on tracks with good grip. The choice depends on the circuit and driving style.

Is this chassis compatible with all NSR bodies?

No. The NSR1410 is specifically designed for the NSR Audi R18 body. Each chassis in the NSR catalogue is adapted to the geometry of its corresponding body.

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

The compatibility of the chassis with the track depends on the complete car assembled, not the chassis itself. The NSR Audi R18 is a competition car that works on universal track, yes, although it is especially oriented towards more precise tracks like wooden ones.

How long does it take to notice the difference when changing chassis hardness?

The difference is noticeable from the first metres on track, especially in corners. We recommend doing several laps with each hardness under the same conditions to objectively assess which one suits your circuit best.

Is any special tool required for assembly?

No special tools are required. A screwdriver suitable for the screws of your NSR car is sufficient. It is advisable to have a caliper on hand if you want to verify the geometry after assembly.
