BRM - Maintanance, Tuning

and information for upgrade to Carrera Digital

Various BRM models

Although BRM has only been on the market for a few years, it has significantly expanded its 1:24 scale offerings. Fans of modern classic cars will especially enjoy them, as the range of GT cars and classics like the Porsche 917 and Ferrari 330/512 is constantly growing.

BRM has particularly struck a chord with these classic cars. Since the cars in the 1970s were considerably smaller, these classic cars fit the Carrera track much better than the Carrera Digital 124 cars.

Chassis BRM

Metal chassis – stable & dynamic driving

Unlike Carrera, BRM relies on a metal chassis. Within a vehicle class, the base plate, engine mount, and keel mount are the same – only the frame is adapted to the body and wheelbase. A highlight: BRM slotcars come without magnets. The metal chassis ensures a low center of gravity and thus realistic handling.

Some models even have negative camber – either on the rear axle or on the individually mounted front wheels.

Maintenance BRM cars – a little more care

A wobbly chassis needs some attention:

  • Check the axle mount screws and any wobble before first use.

  • Check the motor mount (2x 1.5 mm Allen keys, some have 3 screws)

  • Changed sound while racing = check and adjust the motor mount.

Practical tip: Some screws are soft – we prefer Torx T6.

BRM chassis inspection

Quality & chassis check

Since 2025, we've seen a few typical defects in younger classic cars and midgets:

  • Loose screws in the box

  • Engine not properly aligned → gear not engaging

  • Wheel bore too small → needs to be widened to 3 mm

To avoid problems, we offer a chassis check – we check and correct all relevant issues.

BRM slotcar tuning

Behaviour and tuning options

Even in their original condition, BRM slot cars handle very well.

With ground Ortmann tires, things often improve even further.

For those who want even more fine-tuning, there are accessories for adjusting wobble and chassis clearance.

Upgrade BRM to Carrera Digital

Upgrade Carrera Digital

Digital conversion is generally quite feasible. Most models are prepared for the installation of a Carrera Digital decoder. However, in modern classic cars, the motor can cause incorrect measurements in digital mode – running it in and, if necessary, eliminating interference will remedy this.

  • In our opinion, replacing the guide vane is unnecessary (with over 100 conversions a year, we never have any problems)

  • We use the Carrera D132 decoder (12-15 V motors)

  • Many BRM models are already available including upgrade digital from our stock.

  • Thematically, BRM youngtimer are not a perfect fit for Carrera Digital 124.
