0.195mm copper braid - 1 metre

The braid that makes a difference in the current conduction of your 1/32 slot cars

When working on the preparation and tuning of a slot car, few parts have as direct an impact on motor response as the braids. The Sideways SWBR02C Copper Braid offers 1 metre of material with a diameter of 0.195 mm, designed for those seeking efficient current conduction, with minimal resistance and adequate flexibility for work within the chassis.

Function and performance

The braids are the electrical bridge between the guide —which captures the current from the track— and the car's motor. A worn, rigid, or low-quality braid introduces electrical resistance, generates power losses, and can cause current cuts in track areas with little contact. Periodically replacing them, or when preparing a car for competition, is a common practice among the most demanding enthusiasts.

The copper used in this reference allows for high conductivity, and its 1 metre format provides sufficient material for several replacements or to experiment with different lengths and arrangements within the chassis.

Compatibility and assembly

With a diameter of 0.195 mm, this braid fits the most common brush holders in 1/32 scale slot cars. It is essential to verify before assembly that the car's brush holder accepts this thickness, as different chassis may require different measurements.

• Length: 1 metre
• Diameter: 0.195 mm
• Material: copper
• Application scale: 1/32
• Reference: SWBR02C

Assembly and preparation

To achieve the best result, cut the braid to the exact length that allows freedom of movement of the guide without excess material, as unnecessary surplus can hinder the closure of the chassis or cause friction. Ensure that the contact at both ends —brush holder and motor terminal— is firm and clean before soldering. A small amount of flux facilitates soldering and ensures a joint with low electrical resistance.

Common mistakes

• Leaving the original braids too long: with use, they oxidise and harden, losing flexibility and conductivity.
• Cutting without measuring: a braid that is too short tenses the guide; too long creates internal interference.
• Soldering with excessive heat: can melt part of the copper braid and reduce the effective conductive section.

Frequently asked questions

What scale is this braid intended for?

It is designed for 1/32 scale slot cars, which is the most widespread scale in club circuits and recreational use.

How many replacements can I make with 1 metre of braid?

It depends on the length you need for each car, but typically 1 metre allows for between 4 and 8 complete replacements (two braids per car), depending on the chassis.

How do I know if I need to change the braids on my car?

The most common symptoms are power losses, irregular motor response, or current cuts on track, especially in corners where the guide moves laterally. It is also advisable to check them if they show visible oxidation or are rigid to the touch.

Is it necessary to solder the braids or can they be fixed in another way?

Soldering is the recommended method to ensure a clean and durable electrical contact. Mechanical fixings without soldering tend to increase electrical resistance over time.

Is this braid compatible with any brush holder?

It must be verified that the brush holder accepts the diameter of 0.195 mm. Most standard 1/32 brush holders are compatible, but some specific designs may require different measurements.

The Sideways SWBR02C is a 0.195 mm diameter copper braid, sold in a 1-metre length, designed for 1/32 scale slot car preparation. It ensures efficient current transfer between the guide and motor, reducing electrical resistance for a cleaner, more consistent throttle response. A staple spare part for club racers and hobbyists looking to maintain or improve their cars' performance on track.
