Porsche Contact Wires

Chrono SRC contact cables for Porsche 914/6 GT: precision electronics for your competition replica

When a slot car fails on track, the most common cause is not the motor or the chassis, but the electrical chain: a poor connection in the wires or worn braids that no longer transmit current effectively. SRC, known for its demanding work on historical competition replicas, offers these Chrono contact cables specifically developed for its Porsche 914/6 GT, ensuring that the car's electrical system remains in the same condition as when it left the factory.

Kit contents

The SRCRM1502 set includes everything necessary for a complete replacement of the contact system:

• 2 DEC terminals — precision connectors that ensure a solid connection between the wire and the car's contact point.
• 1 + 1 silicone-pro cables of 65 mm — length and material designed for the interior of the 914/6 GT chassis, with good flexibility and heat resistance generated during running sessions.
• 2 standard braids of 22 mm — the braids are the direct contact point with the rail; their condition directly influences driving consistency and controller response.

Function and performance

The braids act as a bridge between the rail and the car's electrical circuit. When they wear out or get dirty, the current arrives irregularly, resulting in micro-failures, abrupt starts, or loss of response in corners. Replacing them along with the cables and terminals — rather than doing it piece by piece — ensures that there are no weak points in the contact chain.

The silicone-pro cable offers adequate conductivity for competitive slot use and superior flexibility compared to standard PVC cables, reducing the risk of internal tensions in the wiring within the chassis.

Compatibility and assembly

This kit is specifically designed for the SRC Porsche 914/6 GT model (reference SRCRM1502). SRC precisely numbers its spare parts for each car in its catalogue, so it is important to confirm that your model matches this reference before placing an order.

The assembly does not require special tools beyond a fine screwdriver and, if desired, a fine-tipped soldering iron with electronics solder for soldering the terminals. Many preparers choose to inspect and clean the contact points of the chassis while changing the braids and cables.

Common mistakes

• Replacing only the braids without checking the condition of the cables: if the cable has cracked insulation or oxidised terminals, the contact problem persists.
• Forcing the DEC terminals without properly aligning them, which can deform them and compromise the connection.
• Reusing old braids "because they still have some material": uneven wear between the two generates differences in resistance and erratic behaviour on the straight.

Frequently asked questions

How often should I change the braids?

It depends on usage, the type of track, and the condition of the rail, but as a general reference, it is advisable to check them every 2-3 intensive running sessions. If you notice that the car loses response or exhibits micro-failures, the braids are the first point to inspect.

Are these braids compatible with other SRC cars?

This kit is specifically catalogued for the SRC Porsche 914/6 GT. Other references from the brand may use different sizes or types of braids. Always check the exact spare part reference for your specific model.

Do I need to solder the DEC terminals?

It is not essential if the terminal fits firmly in its housing, but soldering the joint provides greater electrical security and prevents the vibration of the car on track from loosening the contact over time.

Can I use these cables on a universal track (Scalextric, Ninco)?

The type of track does not affect the internal cables of the car. These cables are part of the internal electrical circuit of the chassis, so they are compatible with any track system as long as the car is configured for that rail.

What is the difference between a standard braid and a competition braid?

Standard braids are suitable for regular club and recreational use. Competition braids typically have a higher density of fibres and better conductivity, designed for timing environments where every millisecond counts. For regular running with the 914/6 GT, the standard 22 mm braids included in this kit are the correct choice according to SRC's own specification.

The SRC SRCRM1502 contact cable set is a specific spare part for the SRC Porsche 914/6 GT slot car, including two DEC terminals, 1+1 silicone-pro cables (65 mm) and two standard braids (22 mm). Designed to maintain reliable electrical contact on the track, this kit is an essential maintenance item for SRC slot car collectors and club racers looking for consistent performance and faithful restoration of their historic racing replica.
