16.2 x 10 UFO Wheel -UNIVERSAL-

The aluminium wheel that redefines dynamic possibilities in 1/32 slot racing

The UFO Universal Wheel SP023004 from Sloting Plus is much more than an aluminium spare part: it is an adjustment platform that allows fine-tuning the car's behaviour according to the track, tyre compound, and driving style. Made from machined duralumin, it weighs just 1.25 grams, a critical factor in competition where every tenth of a gram in the wheels affects inertia and reaction time.

Features and specifications

• Dimensions: 16.2 mm outer diameter × 10 mm width
• Material: Machined duralumin
• Weight: 1.25 g per unit
• Fixing: M2.5 × 3 mm allen screw
• Contents of the bag: 2 wheels + 4 foams + 2 M2.5 × 3 mm screws
• Family: UFO — Universal version

Function and performance

The UFO design introduces a distinctive feature: the ability to mount the wheel with or without inner foam. This dual configuration is not cosmetic; it effectively changes the stiffness of the mounted wheel and, therefore, the contact surface with the track and the response to track irregularities.

• Without foam: more direct and predictable behaviour, ideal for smooth wooden tracks where precision and immediate response are sought.
• With foam: the wheel absorbs micro-vibrations and allows the tyre to work with a larger contact surface, especially useful on plastic tracks with more surface variation.

The four foams included in the bag allow experimentation with different compounds or hardness levels (depending on the type of foam you choose to mount), giving the preparer a fine-tuning margin without changing the wheel.

Compatibility and mounting

The Universal version of the UFO family is designed to accommodate brake disc and hub cap of different designs, expanding aesthetic options without sacrificing any dynamic performance. This is a particularly valued advantage in competition preparations where the visual aspect of the wheel also matters.

The included M2.5 × 3 mm allen screw is the fixing element to the axle. It is advisable to ensure that the car's axle is compatible with this type of fixing before installation. The adjustment should be made with the appropriate allen key, tightening firmly but without overdoing it to avoid damaging the thread of the duralumin.

Assembly and preparation

1. Clean the rear axle and ensure it is free of adhesive residue or dirt.
2. If you opt for the configuration with foam, insert the foam into the wheel's housing before mounting the tyre.
3. Place the wheel on the axle and tighten the M2.5 × 3 mm screw with the corresponding allen key.
4. Check the centring and parallelism with the wheel on the opposite side before the first run.
5. If you add a brake disc or hub cap, secure them before finally adjusting the wheel.

Common mistakes

• Over-tightening the screw: duralumin is lightweight and strong, but the thread can be damaged if forced. Tighten until the wheel does not spin freely on the axle, without overdoing it.
• Mounting the foam without checking its thickness: different foam compounds yield different wheel profiles. Always test on a bench before taking the car to the track.
• Not checking the centring: a slightly eccentric wheel causes vibration at high speed. Use a truing bench to ensure the roundness of the wheel-tyre assembly.

Frequently asked questions

How many wheels are included in the bag?

The SP023004 bag includes 2 UFO Universal wheels of 16.2 × 10 mm, along with 4 foams and 2 M2.5 × 3 mm allen screws.

Can I use these wheels without foam?

Yes. The UFO design allows them to be mounted with or without inner foam. Without foam, the behaviour is stiffer and more direct; with foam, you gain adaptability and vibration absorption.

What is the difference between the Universal version and the R version of the UFO family?

The Universal version (this wheel) allows the addition of brake discs and hub caps of different designs, expanding aesthetic options. The R version is aimed at a more specific competition profile. Check the datasheets of each reference to choose the one that best suits your preparation.

What tyres are compatible?

Being a wheel of 16.2 × 10 mm, it is compatible with Sloting Plus tyres designed for that wheel size. Always check the inner diameter of the tyre before mounting.

What allen key do I need for the M2.5 screw?

You need a 1.3 mm allen key for the included M2.5 × 3 mm screw. It is the standard size in most slot preparation tool kits.

Are these wheels suitable for club competition?

Yes. The machined duralumin, the weight of 1.25 g, and the ability to adjust the configuration with or without foam make them suitable for competitive environments where fine tuning makes a difference.

The Sloting Plus SP023004 UFO Universal wheel (16.2 x 10 mm) is a precision-machined duralumin slot car wheel designed for 1/32 scale competition and club racing. Weighing just 1.25 g, it can be run with or without foam insert, allowing the driver to tune grip and compliance for both plastic and wooden tracks. Each bag contains 2 wheels, 4 foam inserts and 2 M2.5 × 3 mm allen grub screws. Compatible with brake disc and hub cap accessories from the UFO range, making it a versatile choice for both performance preparation and visual finishing.
