Neodymium Magnet Ø8×5

A competition neodymium magnet for the most iconic prototypes of the 70s

The neodymium magnet Ø8×5 SRC RM1209 is a competition spare part designed to keep your cars in the best possible condition on the track. With dimensions of 8 mm in diameter and 5 mm in height, this magnet is conceived to provide the grip force and magnetic response demanded by competitive driving.

Function and performance

The magnet is one of the key elements in a slot car: it determines the adherence to the track, cornering behaviour, and the overall stability of the model. A worn or incorrectly specified magnet can ruin the setup of a perfectly prepared car in the rest of its components. Replacing it with a new one of the exact dimensions restores the original behaviour of the model and ensures a solid foundation for any subsequent adjustments.

Neodymium is the reference material in competition: it offers a magnetic flux density far superior to conventional ferrite magnets, with a contained weight that does not penalise the mass distribution of the car.

Compatibility

According to information provided by SRC, this magnet is suitable for the following models:

• Ferrari 312 PB / Ferrari 312 CL
• Lola T280
• Lola T290

If you have any of these prototypes in your collection or use them in your club championship, the RM1209 is the direct replacement you need to keep them at competition level.

Installation and preparation

Installation is straightforward: remove the worn or damaged magnet from its housing in the chassis and place the new one, ensuring that the correct polarity is respected. A well-seated magnet should not move within its cavity. If there is any play, a small dot of contact glue on the sides —never on the magnetic faces— can resolve the issue without compromising future disassembly.

Before closing the chassis, check with a magnetic field meter or through practical testing on the track that the grip is as expected. A new magnet usually offers more adherence than a used one, so it may be advisable to slightly adjust the guide height or spring stiffness to balance the setup.

Ideal for…

• Drivers competing with Ferrari 312 PB/CL or Lola T280/T290 in club championships.
• Collectors looking to restore the original behaviour of their SRC models.
• Enthusiasts performing preventive maintenance on their fleet of cars.

Frequently asked questions

When should I replace the magnet in my slot car?

The most common sign is a progressive loss of grip in corners, especially in high-speed areas. The magnet may also show cracks, be broken, or have lost part of its coating. In any of these cases, replacement is the most direct and economical solution.

Can I use this magnet in other models not listed?

We only recommend using it in the models specified by SRC: Ferrari 312 PB/CL and Lola T280/T290. Although dimensionally it may fit in other chassis with the same housing, we cannot guarantee compatibility or performance in models not specified by the manufacturer.

Is the neodymium magnet more powerful than the original factory one?

SRC already equips its competition models with neodymium magnets, so this RM1209 is a replacement of specifications equivalent to the original, not a power upgrade. Its purpose is to restore the car's performance as it came from the factory.

Does polarity affect performance?

Yes. If you mount the magnet with the polarity reversed, the car may experience a repulsion effect with the track instead of attraction, drastically reducing grip. Always check the correct orientation before closing the chassis.

The SRC RM1209 is a neodymium replacement magnet measuring Ø8×5 mm, designed for competition-level slot car racing. Compatible with the Ferrari 312 PB, Ferrari 312 CL, Lola T280 and Lola T290, it restores original magnetic downforce and handling characteristics. A must-have spare part for serious club racers and SRC collectors looking to keep their 1970s prototype models performing at their best.
