On the SCX cars you can adjust the magnet pull by adjusting the two screws on the magnet holder under the car.

To get more magnet pull loosen the screws (but not so much that the holder starts to rub on the track).

To get less magnet pull, screw the whole magnet holder with the magnet out of the car, turn the holder 180 degrees and re-assemble. This allows the magnet holder to be adjusted further into the chassis, hence making the magnet effect weaker.

Does your Scalextric cars have brown or shiny magnets? I suspect you got cars with the old weak brown magnets mounted under the chassis, if so then there are no direct replacement magnets to buy, but you can always hotglue a new type magnet inside the chassis to increase the magnetic pull.

If you should ever get tired of the stuck down feeling, insane speeds and hard crashes that modern magnets tend to make, then put them on your fridge door and come over to the no-mag world of sticky urethane tires. balancing weights lower track voltage

You can re-thread the SCX braids to a "single braid setup" like this:

This gives the braids less "spring" effect which help to plant the guide better into the slot. To "restore" the braids before re-installing, drag them between your thumb nail and your index finger.

I used WD40 to clean tires for years, then converted to rolling tires on packing tape, but now I only use a damp cloth (water) to spin the tires on and have just as good grip (if not better) than before. The key is to "rubber in" your track to lay down a rubber film which increase grip, and then keep the track dust free using microfibre cloth and/or a vacum cleaner.

As for tires I would recommend to stay away from silicone. They give great grip but they can be difficult to sand/true and when most stock wheels are out of round, it means that to get a good contact path on a silicone tire you often need to replace the wheels with alu-wheels which again often require a new axle, bushing and/or gears, in other words an expensive route. In addition they tend to reduce the grip for stock tires and other rubber/urethane tires by erasing the "rubber film" that rubber and urethane tires lay down. As mentioned that rubber film is very important to get good grip on stock/rubber/urethane tires, especially with low or no mag pull.
