NSR ultrasoft copper braid (10pcs)

NSR Ultrasoft Copper Braids: Precise Contact, Clean Driving

Braids are one of those small details that make a real difference in the behaviour of a slot car. This NSR reference (NSR4822) comes in a pack of 10 units and is made of copper with an ultrasoft designation that defines its main virtue: exceptional flexibility that ensures constant and uniform contact with the track.

Technical Features

• Dimensions: 3.5 × 34 mm
• Thickness: 0.2 mm
• Material: ultrasoft braided copper
• Pack Contents: 10 units
• Reference: NSR4822

Function and Performance

The function of the braids is to transmit current from the track to the motor through the guide. The lower the resistance of that contact and the more constant the support, the smoother and more controllable the driving becomes. The ultrasoft material of these NSR braids naturally adapts to the irregularities of the track, minimising micro-cuts and maintaining stable power even in fast corners or sections where the car experiences greater lateral load.

The thickness of 0.2 mm places them in the fine range, which helps reduce the unsprung weight on the guide and makes the throttle response more direct. For competitive setups or for those looking to maximise the performance of their car in a club, this type of braid makes a difference compared to stiffer or thicker options.

Compatibility and Installation

NSR braids are compatible with standard guides from the brand itself and, in general, with most guides on the market that accept the 3.5 mm width format. Their installation is straightforward: they fit into the side slots of the guide and are secured with the corresponding screw or clip depending on the model. Being ultrasoft, they take the shape of the guide without forcing, which facilitates installation and prolongs their lifespan.

It is advisable to regularly check the condition of the braids, especially after long running sessions, as progressive wear can affect contact and, consequently, the uniformity of driving.

Ideal for…

• Club racers looking to optimise every component of their car.
• Enthusiasts preparing NSR or compatible cars for competition.
• Any setup where improved current transmission is desired compared to standard braids.
• Always having spares on hand: with 10 units per pack, there is enough material for several replacements.

Common Mistakes

One of the most common mistakes is installing the braids with too much tension, bending them excessively when placing them. This hardens the support and counteracts the advantage of the ultrasoft type. Ideally, they should have a slight natural curvature towards the track, without forcing the shape. It is also advisable to clean the tracks before using new braids: accumulated dirt accelerates wear and reduces conductivity from the very first moment.

Frequently Asked Questions

How many braids are included in the NSR4822 pack?

The pack includes 10 units.

What does "ultrasoft" mean in these braids?

It indicates that the braided copper is particularly soft and flexible, allowing for a more constant and natural support on the track, reducing contact resistance and micro-cuts in current.

Are they compatible with guides from other brands?

Generally yes, as long as the guide accepts braids of 3.5 mm width. However, it is advisable to check compatibility with the specific guide model before installation.

How often should the braids be changed?

It depends on usage, the condition of the track, and whether the car is used in competition or recreational running. As a guideline, it is good practice to check them after each long session and replace them when visible wear or loss of flexibility is noticed.

Do these braids reduce the motor's electrical consumption?

They do not reduce the motor's consumption per se, but by improving the efficiency of the electrical contact, they minimise voltage losses between the track and the motor, resulting in a more linear throttle response.
