PICK-UP GUIDE SPACERS .020" BRASS (10pcs) by NSR

The millimetric adjustment of the guide that makes a difference in every corner

When aiming to extract the maximum performance from a competition slot car, the small details matter. The NSR brass guide spacers (ref. NSR4820) allow for precise adjustment of the height at which the guide operates relative to the chassis, directly influencing the car's stability and the quality of the electrical contact of the braids with the rail.

Function and performance

Each spacer has a thickness of 0.020" (0.50 mm) and is made from brass, a material that combines lightness, strength, and minimal compression under load. Its main function is to raise or level the position of the guide within the chassis housing, which affects:

• The depth of penetration of the guide into the rail.
• The contact pressure of the braids.
• The car's behaviour in chicanes and quick transitions.

An incorrect adjustment of the guide height is one of the most common causes of loss of electrical contact or a guide that "jumps" in tight corners. With these spacers, that adjustment becomes fully controlled.

Compatibility

Designed by NSR for their own guides, they are compatible with the chassis and guide systems of the NSR range. Before using them on chassis from other brands, it is advisable to check the inner diameter of the guide housing and the exact reference of the guide used.

Assembly and preparation

Assembly is straightforward: place the necessary number of spacers under the guide before securing the screw or retaining pin. Starting from the factory configuration, it is common to begin with a single spacer and test the behaviour on track, adding or removing according to the results. The pack includes 10 units, allowing for experimentation with different configurations and having spare stock.

Common mistakes

• Stacking too many spacers: excessively raising the guide can lead to loss of grip in corners and a higher risk of derailment.
• Not checking the leveling: if the chassis is not well levelled from the start, the spacers will not resolve the problem on their own.
• Mixing different thicknesses: if this spacer is combined with others of different thickness, it is important to record the exact combination for reproduction.

Ideal for…

Club drivers fine-tuning their NSR setup before a race, preparers working on multiple cars at once and needing spare stock, and enthusiasts wanting to understand and control every variable of their slot car.

Frequently asked questions

How many spacers are usually used?

The most common in competition preparation is to use between one and three spacers, depending on the type of chassis and rail. The best reference is always track testing with the specific configuration of each car.

Are they reusable?

Yes. Being made of solid brass and not subjected to plastic deformation under normal use conditions, they can be disassembled and reused without issue.

Do they work for guides from other brands like Slot.it or Scaleauto?

They are designed for NSR guides. Compatibility with guides from other brands depends on the diameter of the stem and the chassis housing. We recommend checking the measurements before installing them on a chassis from another brand.

What is the difference between adjusting the guide height and changing the type of guide?

Changing the type of guide affects the contact geometry with the rail and its width. Adjusting the height using spacers acts on the insertion depth and the pressure of the braids, being a finer and reversible intervention.
