BM4 GT3 V. Rossi and M. Martin 2024 GT World Challenge Europe

Sideways recreates the BM4 GT3 with which Valentino Rossi competed in the GT World Challenge Europe 2024

With the reference SWCAR09A, Sideways brings to the track one of the most historically rich models in its catalogue: the BM4 GT3 decorated with the livery worn by Valentino Rossi and Maxime Martin during the 2024 season of the GT World Challenge Europe. The figure of "The Doctor" in the automotive world has generated enormous anticipation among collectors and slot racers, and this model meets that expectation point by point.

Decoration and exterior detail

The tampography accurately reproduces the sponsors, race numbers, colours, and aerodynamic appendages of the real car. The deflectors, rear wing, and side mirrors are crafted with the level of finish that characterises Sideways in the modern GT category, making the model stand out both in a display case and on any track.

Mechanical configuration: ready to race

Sideways has equipped this BM4 GT3 with a competition-oriented mechanics from the outset:

• Red Anglewinder chassis (0.7 mm): the motor is mounted at an angle to the rear axle, lowering the centre of gravity and improving mechanical grip and magnetic effect on the rail.
• Baby Raptor motor (17,000 RPM): delivers progressive and docile power, with very usable torque in twisty sections. Ideal for GT championships where control is paramount over top speed.
• Pinion/crown gear ratio 11/28 teeth: balance between acceleration and stability during braking at the end of the straight.
• Front axle: 55.5 mm axle with 17.3 × 8.2 mm wheels and Ultra-Hard tyres of 70 Shore (19 × 10 mm), minimising front friction and ensuring just the right support in the guide.
• Rear axle: 56.5 mm axle with Air System wheels (17.3 × 8.2 mm) to dampen rebounds, and Prospeed Medium 22 Shore tyres (code PS1mw-ng, 20 × 11 mm): excellent balance between grip and durability on both plastic and wooden tracks.

Track behaviour

The combination of the Anglewinder chassis with the Baby Raptor and Prospeed Medium makes this BM4 a very easy car to push to the limit. The low centre of gravity favours cornering and reduces oversteer. The standard braids ensure good electrical contact from the first lap, and the standard guide from Sideways fits seamlessly into the main track systems on the market.

Ideal for…

• Collectors who follow Valentino Rossi's automotive career and want the piece from the 2024 season.
• Club racers competing in modern GT categories looking for a competitive car without the need for extensive initial preparations.
• Enthusiasts who want to combine high-level aesthetics with real dynamic behaviour on the track.

Aspects to consider

The model comes out of the box configured for competition, but like any high-end slot car, a small break-in period, fine-tuning of the guide, and checking the crown gear tightness can make a difference in the first practice sessions. The Prospeed Medium tyres perform particularly well on wooden tracks; on plastic tracks, it may be worth comparing with slightly higher Shore options depending on local conditions.

Frequently asked questions

Is this BM4 GT3 compatible with Scalextric and Ninco tracks?

Yes. The standard guide from Sideways is compatible with universal rail, which includes systems like Scalextric and Ninco. For tracks with sport rail (Scaleauto, Slot.it), it will be sufficient to change the guide for one with a sport profile.

What type of motorisation does it have exactly?

It features an Anglewinder configuration: the Baby Raptor motor is installed at an angle to the rear axle, which differentiates this system from the Sidewinder (motor parallel to the axle) and the Inline (motor in line with the car). This layout lowers the centre of gravity and improves stability in corners.

Does the car come fully assembled and ready to run?

Yes, the SWCAR09A is a Ready to Run model: it comes out of the box fully assembled with all its mechanical components installed. You just need to place it on the track and connect the power.

Are the Prospeed Medium tyres suitable for club racing?

They are one of the most commonly used references in GT racing precisely because of their balance between grip and wear. They perform very well on wooden tracks and offer predictable behaviour on plastic. Many club regulations accept them directly out of the box.

Is it possible to replace the Baby Raptor motor with a more powerful one?

The Anglewinder chassis from Sideways accepts standard format motors of 18,000 or 21,000 RPM compatible with that configuration. However, for championships regulated by motor category, it is advisable to check the regulations before making any changes.

What is the difference between Air System wheels and conventional wheels?

The Air System wheels incorporate a small air chamber that absorbs track irregularities, reducing rebounds in the rear axle and improving stability at high speeds. It is a common solution from Sideways in its competition-oriented models.

The Sideways SWCAR09A BM4 GT3 Valentino Rossi Maxime Martin 2024 GT World Challenge Europe is a highly detailed 1/32 scale slot car featuring Anglewinder motor mount, Baby Raptor 17K motor, Air System rear wheels and Prospeed Medium tyres. A must-have for GT3 slot racing collectors and competitive club racers looking for a race-ready model straight from the box.
