About

ARM products on a rally stage

ARM products designs and builds rally computers and tripmeters in Ibaraki, Japan. We started in 2011 with one aim: to make rallying more affordable for the people who love it.

Started by a privateer

Our founder competed as a privateer and made it all the way to the World Rally Championship. Along the way, one problem kept coming back: rally equipment was expensive, and every piece of kit took budget away from the driving itself.

So in 2011 we built our first product, a rally computer application. If crews could do more with less money spent on equipment, they could spend more of their time, and their budget, on the stages.

Rallying as a privateer

Less spent on equipment. More time on the stage.

That idea still shapes everything we make. Our line-up now covers GPS and speed-signal tripmeters and rally computers, and the aim hasn’t changed: professional-grade precision at a price that keeps you rallying.

Built in Ibaraki, shaped by crews

Every unit is designed and built at our own workshop in Ibaraki, Japan. Because design and building happen under one roof, what crews tell us goes straight into the next version.

Your ARM in the field

ARM products supporting a crew at a rally

At ARM, we don’t stop at turning ideas into products. We work as your arm, the ARM in our name, out in the field, supporting crews at rallies around the world.

From the workbench to the service park, one team stands behind every unit.

From building each unit to supporting it long after you’ve bought it, we handle everything ourselves. That unbroken line of service is the soul of what we do.

On the stage with crews worldwide

From privateers on their first event to manufacturer teams, crews around the world rally with ARM products. These are some of the teams we’ve been proud to support.
