NSR Ultralight 17X10mm Wheels: Less Weight, More Response
When it comes to serious slot car preparation, every gram in the wheels counts. The Ultralight wheels from NSR in size 17X10mm (reference NSR5004) are designed precisely for that: to reduce unsprung mass on the axle, improve acceleration, and make the car respond more faithfully to the controller's commands.
Function and Performance
The designation Ultralight is not coincidental. NSR applies a manufacturing process in this range aimed at minimizing the weight of the wheel without compromising its stiffness or the concentricity of the assembly. The result is a wheel that rotates with less inertia, which translates to:
- Better acceleration response, especially on technical circuits with many chicanes.
- Less load on the motor at the start of movement.
- Greater stability by keeping the tyre perfectly centred on the axle.
The size 17X10mm corresponds to the outer diameter and width, respectively. It is a common combination on the rear axle of many 1/32 scale slot cars, although it is always advisable to verify compatibility with the chassis and the tyre to be mounted.
Compatibility and Installation
NSR is a leading brand in slot car spare parts, with a carefully organised catalogue that facilitates preparation work. These wheels are intended to be used with tyres from the NSR range or with other tyres of equivalent size. Before installation, it is recommended to:
- Check that the inner diameter of the wheel fits the car's axle.
- Verify that the width (10mm) is compatible with the available space between the fenders or bodywork.
- Use a specific adhesive for slot car tyres when securing the rubber, applying just the right amount to avoid altering the balance of the assembly.
Common Mistakes
A common mistake is confusing the diameter of the wheel with that of the mounted tyre: the tyre adds its own wall thickness, so the final diameter of the wheel+tyre assembly will always be greater. Keeping this in mind is key to avoiding contact with the bodywork or losing the car's height adjustment.
Another point to watch is balancing: no matter how precise an Ultralight wheel is, if the tyre is not well centred or has excess glue at one point, the weight advantage is lost. Taking a few extra minutes during installation is always worthwhile.
Ideal for…
These wheels fit particularly well with driver profiles that approach slot racing with a preparer's mindset: those who time laps, compare setups, and seek to extract every tenth from the rear end. They are also a good option for those who already recognise that the standard stock wheel leaves room for improvement and want to take a concrete step in that direction.
Frequently Asked Questions
What does the size 17X10mm actually mean?
The first number (17mm) indicates the outer diameter of the wheel, and the second (10mm) its width. These are the dimensions specific to the wheel, excluding the tyre mounted on it.
Which tyres are compatible with these wheels?
They are compatible with tyres from the NSR range of equivalent size. For other brands, it is necessary to check that the inner profile of the tyre fits correctly to the outer diameter of the wheel.
How many wheels are included in the NSR5004 pack?
The manufacturer's information does not specify the exact number of units per pack in the available documentation. We recommend contacting us directly before placing your order if you need to confirm this.
What advantage does an Ultralight wheel have over a standard wheel?
The main advantage is the reduction of rotational mass: being lighter, the wheel offers less resistance to rotation, which improves acceleration response and reduces motor effort. On technical circuits, this can make a real difference in lap times.
Are they suitable for club racing?
Yes, as long as the championship regulations allow the use of aftermarket parts or those from the NSR brand itself. It is advisable to review the technical rules of the championship before mounting these wheels on a competition car.
NSR Ultralight 17X10mm slot car wheels (NSR5004) are a precision component designed to reduce rotational mass on the rear axle of 1/32 scale slot cars. Lightweight construction improves throttle response and acceleration, making them a popular upgrade choice among serious club racers and slot car enthusiasts. Compatible with NSR tyres and equivalent profiles, these wheels are part of NSR's renowned aftermarket parts catalogue, widely available at specialist slot car shops across Europe.
