SC-3DP Racing Guide with Screw. Dimensions: 24.3x8mm

Precision and grip in every corner: the SC-3DP Racing guide from Scaleauto with screw

The guide is one of the most critical elements of any slot car: it determines contact with the track, current pickup, and stability during braking and cornering. Scaleauto knows this well, which is why it has designed this SC-3DP Racing guide with a clear focus on competition and car preparation.

Function and performance

The SC-3DP Racing guide with screw is designed for direct mounting with screw fixation, making adjustment and quick replacement during a race session or on the workbench easier. Its dimensions of 24.3 x 8 mm and a pin of 3.5 mm place it within the standard competition range, with a profile that promotes stable contact with the track and reduces unintended departures.

The high-precision 3D printing manufacturing — hence the 3DP designation — allows for very controlled and repeatable geometries, with tight tolerances that translate into predictable behaviour on the track.

Compatibility

Designed for the Scaleauto spare parts ecosystem, this guide is compatible with the chassis and bodies of the brand that accept standard guides with screw fixation. Always check the dimensions of your chassis's housing before installing it to ensure a proper fit.

Assembly and preparation

• The screw fixation allows for controlled and repeatable tightening.
• The 3.5 mm pin fits into standard competition housings.
• Check the condition of the braids and their contact with the guide before each session.
• It is recommended to lightly sand the base of the guide if excessive play is detected in the housing.

Ideal for…

This guide is designed for enthusiasts preparing their cars for club championships or looking to improve the response of their Scaleauto models on Sport track. It is also a practical option for those who wish to have spare units on hand and streamline changes between heats.

Each pack includes 2 units.

Common mistakes

• Do not confuse the 3.5 mm pin with other diameters: incorrect mounting generates play and loss of contact.
• Over-tightening the screw can deform the chassis housing; adjust firmly but without forcing.
• Changing the guide without checking the braids can mask contact problems that persist after the change.

Frequently asked questions

The acronym 3DP refers to the precision 3D printing manufacturing process that Scaleauto uses to achieve controlled geometries and tight tolerances in its competition guides.

How many units does the pack contain?

Each pack contains 2 units of the SC-3DP Racing guide with screw.

Is it compatible with Scalextric or Ninco tracks (universal track)?

This guide is sized for competition and can work on different types of track, but its design and fixation system are oriented towards the Scaleauto ecosystem. Verify the dimensions of your chassis before installing it on other systems.
