Maximum grip on wood: NSR's heavy additive for when the track demands it all
When racing on wooden tracks, the surface has very different characteristics compared to plastic: greater porosity, different temperature, and an interaction with the tyre that requires a specific additive. The NSR4603 Heavy Wheel Additive is formulated precisely to extract the maximum performance from tyres on this type of track, providing a high level of grip that translates into cleaner starts, more precise corners, and lower lap times.
Function and performance
The heavy variant from NSR is designed for those seeking the highest level of adhesion possible on wood. This type of additive acts on the tyre surface, increasing the coefficient of friction with the track, which is particularly noticeable in tight corners and during braking. It is a widely used option in club racing, where milliseconds make the difference.
- Heavy formulation: high grip, ideal for wooden tracks.
- Improves corner traction and overall car stability.
- Easy to use and direct application on the tyre.
- Reference: NSR4603.
When to use the heavy version?
The choice between a soft, medium, or heavy additive mainly depends on the type of track and the racing conditions. On wooden tracks, especially when they are cold or not well run-in, a heavy additive helps to compensate for the lower initial grip. It is also recommended on circuits with many slow corners, where mechanical grip is more significant than top speed.
Compatibility and usage
This NSR additive is aimed at rubber tyres for slot cars in 1/32 scale on wooden tracks. Apply it sparingly on the tyre tread, let it rest for a few moments, and run a few warm-up laps to ensure even distribution. It is not necessary to apply excessively: a controlled amount offers better results and greater longevity.
Frequently asked questions
Can I use this additive on plastic track?
It is specifically formulated for wooden track. On plastic track, it may be excessive and cause grip that is difficult to control. For plastic, NSR offers other variants with a softer formulation.
How often should I apply it?
It depends on the number of laps and the track conditions. As a reference, many drivers apply it at the start of each session and check the car's behaviour after a few warm-up laps before deciding whether to add more.
Is it compatible with all NSR tyres?
Yes, it is designed for NSR rubber tyres. It may also work with tyres from other brands, although the results may vary depending on the rubber composition.
Does it affect tyre wear?
Moderate use does not significantly accelerate wear. Applying too much additive repeatedly can soften the rubber over time, so it is recommended to use it judiciously and in the right amount.
