H 3mm spacers for 1/24 Minicars

Reference BRM-S415D: 3 mm H-spacers for fine-tuning the mechanics of your 1/24 Minicars

In competitive slot racing, the smallest details make the difference between a car that skids through corners and one that tracks securely. The 3 mm H-spacers from BRM, reference BRM-S415D, are one of those discreet yet decisive components: a precision adjustment element specifically designed for the axles of the 1/24 Minicars range.

Function and performance

The "H" shaped design serves a very specific technical function: by seating against the bearing and the wheel, it minimises the contact surface between parts, which directly translates into reduced mechanical friction. The result is an axle that spins freely, without rubbing against the chassis or the bodywork.

With a thickness of 3 mm, these spacers allow for lateral adjustment of the wheel to:

• Precisely adjust the track width to millimetric accuracy.
• Centre the crown gear relative to the pinion and eliminate misalignment.
• Separate the wheels from the bodywork and avoid rubbing that penalises performance.
• Eliminate lateral play in the axle, improving corner stability and consistency in power delivery.

Compatibility

These spacers are designed for the axles of the BRM Minicars series in 1/24 scale. Using official BRM spare parts ensures that the inner diameter of the spacer fits perfectly with the axle, without play that generates vibrations at high revolutions or tightness that complicates disassembly.

Assembly and preparation

Assembly is straightforward: the spacer is placed on the axle between the bearing and the wheel, in the number of units necessary to achieve the desired displacement. Before securing the wheels, it is advisable to check that the axle spins freely and that the crown gear maintains its alignment with the pinion. A small manual turn of the axle with the wheels mounted confirms that there is no lateral rubbing.

Thanks to their durable materials, the spacers do not deform under the pressure of the wheel fixing screw, ensuring that the chosen configuration remains stable throughout the racing session.

Common errors

• Accumulating too many spacers without checking the alignment of the crown gear: every millimetre of lateral displacement affects the engagement of the drivetrain. Always adjust with the car in hand and check the play of the crown gear.
• Mixing spacers from different manufacturers: the tolerances of the inner diameter may vary. To ensure the exact fit with BRM Minicars axles, it is most reliable to use spare parts from the same brand.
• Not checking for lateral rubbing after assembly: a poorly seated spacer can reproduce exactly the problem it was meant to solve. Always perform a final check before putting the car on track.

Frequently asked questions

Which BRM models are these spacers compatible with?

They are specifically designed for the axles of the BRM Minicars series in 1/24 scale. Check the parts list of your model to confirm that the axle diameter is suitable before placing your order.

How many spacers does the reference BRM-S415D include?

The information provided by the manufacturer does not specify the exact number of units per blister. We recommend checking the product sheet in-store or contacting our team to confirm before your order.

Can I use these spacers on other 1/24 scale axles that are not BRM?

They are designed for BRM Minicars axles. Compatibility with axles from other brands depends on them sharing the same diameter, something we cannot guarantee without prior verification.

What is the difference between a 1 mm, 2 mm, and 3 mm spacer?

The thickness determines how much the wheel or crown gear is displaced laterally. For small centering adjustments, 1 mm spacers are used; for broader corrections of track width or body separation, 2 mm or 3 mm spacers like this BRM-S415D are the usual choice.

Does using spacers affect motor performance?

A well-mounted spacer does not penalise the motor; on the contrary, by eliminating lateral rubbing and improving the alignment of the drivetrain, it can help the motor work with less resistance. Negative impact occurs when mounted incorrectly, causing misalignment of the crown gear.
