Ultimate Guide to Breaking in Your New 1/32 Slot Car

One of the most fun hobbies around, slot car racing is the go-to fun activity you can enjoy with friends and family. Race your slot car around the track or make it more competitive by adding chicanes and difficult turns, if you are new to the slot car genre, here are some helpful tips on breaking-in your car to achieve better performance.

Breaking in the Rear Wheels

Slot cars are all rear wheel drive so it is quite essential that the rear wheel does not get stuck. To break-in the new slot car wheels hold the car upside down in one hand and then gently spin the rear wheel using your thumb. If you notice that the wheel does not spin at all, most likely the rear axle assembly or the motor is out of position. Simply check and snap them into place.

Check the Braids are frayed

The copper brushes that touch the metal rails which is also the source of electricity to power the car are called braids. Most of the time, new slot cars run sporadically because they do not come in good contact with the track rails. The braids are often wound very tightly and do not create good electrical conductivity. In order to do a proper breaking-in,  you will need a pocket knife and a straight pin. If you have none of these, you can use your thumb to work the ends of the braids until they separate and become frayed. You then curl them down so they come in contact with the track.


Do not go full-speed with your new Carrera slot car when you take it out of the box. Break it in by running at least twenty laps around the track at half to three quarters the speed. This will ensure you get the most performance from your new slot car.

Don’t Forget to Lubricate

Use white grease to the gears and a little bit of oil on the drive shaft and motor as well as the axle bushings. Do not forget to wipe off any excess lubricant in order to avoid build-up, which can clog or attract dirt and debris.
