Bronze central support

Avant Slot Bronze Mount: Weight Control Where It Matters Most

In slot racing, fine-tuning the weight distribution makes the difference between a car that loses grip in fast corners and one that confidently stays on track. This central bronze mount (reference av20572) from Avant Slot is designed precisely for that: to concentrate weight in the low and central area of the chassis, where its effect on the centre of gravity is maximised.

Function and Performance

The high-density machined bronze that makes up this piece is not a casual choice. Unlike plastic or aluminium, bronze allows for the addition of significant mass in a reduced volume, making it ideal when the goal is functional ballast without taking up extra space in the chassis. The piece simultaneously serves its structural function as a mount — securing the motor-axle assembly — and its dynamic function as ballast, without compromising either.

The result on track is immediately noticeable: increased rear traction, reduced tendency to "roll" in elevation changes or linked corners, and a smoother, more controllable response when opening the throttle out of a corner.

Compatibility and Installation

This mount belongs to the 1/32 spare parts range from Avant Slot. It is designed to fit precisely in the brand's chassis, ensuring a snug fit that prevents parasitic vibrations during operation. Before installing it, it is advisable to check in the manual or parts diagram of the specific model that reference av20572 corresponds to your vehicle, as Avant Slot maintains a specific spare parts catalogue by model.

Installation does not require special tools: with the usual slot preparation tools — precision screwdriver and appropriate Allen key — the replacement is straightforward. We recommend checking the tightness after the first sessions to ensure the piece is seated correctly.

Preparation and Tuning

More experienced tuners combine the use of bronze mounts with fine adjustments of tyre hardness and chassis height to make the most of the new weight distribution. A chassis that gains central mass may allow for a reduction in added weight at other points, keeping the total within category limits while improving distribution. It is one of the tuning modifications with the best cost-benefit ratio for rally or speed cars that suffer from a lack of traction.

Common Mistakes

• Installing a bronze mount on an already heavy chassis without removing ballast from other points can push the assembly over the regulatory weight. Always weigh the complete car before and after.
• Not verifying exact compatibility with the model: Avant Slot has specific mounts for each chassis; consult the official parts diagram before ordering.
• Excessive tightening: bronze is strong, but the screws securing it to the chassis can damage the plastic thread if tightened too forcefully. Adjust carefully.

Frequently Asked Questions

Which specific Avant Slot model is the av20572 designed for?

The reference av20572 corresponds to the 1/32 spare parts range from Avant Slot. We recommend checking the parts diagram of the specific model on the official Avant Slot website or contacting us to confirm exact compatibility with your vehicle.

How much weight does this mount add compared to the original piece?

We do not have the exact weight data published by Avant Slot for this reference. The increase depends on the original material it replaces; in any case, bronze is significantly denser than standard plastic, so the mass increase is noticeable. Weigh the assembly before and after the change if you compete in weight-limited categories.

Does it improve traction on any type of track?

Yes. By lowering the centre of gravity and increasing the load on the rear axle, the traction improvement is effective on both Scalextric/Ninco (universal) and Scaleauto/Slot.it (Sport) tracks. The effect may vary depending on the layout and track conditions, but generally, cars gain stability in fast corners and transitions.

Can I use this mount as the only ballast, or is it better to combine it with other weights?

It depends on the base weight of your chassis and the demands of your category. The bronze mount is functional ballast — it also serves a structural purpose — but many tuners combine it with other tuning adjustments. It is not incompatible with additional weights, as long as the total remains within the regulations.

Is it difficult to install for someone without preparation experience?

The installation is straightforward if you have previously disassembled your slot car chassis. With basic precision tools and following the model's parts diagram, the process is direct. If it is your first time opening a chassis of this brand, we recommend relying on community slot tutorials or consulting us.
