Motorsport Technical Support, Repairs & Race-Car Setup

It’s the putting right that counts. We have raced, engineered, diagnosed and repaired motorsport systems at professional and international level. We do not just sell boxes. We bring the experience to find what is actually wrong, understand how a system behaves in the car and work out the right fix.

Whether the problem is a failed helmet microphone, a damaged connector, an unreliable radio link, poor intercom audio or a race-car setup question, we look at the whole situation before recommending parts or work. A practical repair may cost less than replacing an entire system. Where replacement is the safer or more reliable answer, we explain why.

Qualified radio engineering, built on decades of motorsport

Rex Harris is a qualified Radio Telecommunications Engineer, a New Zealand Approved Radio Certifier (ARC 127) and an Approved Radio Engineer (ARE). His Radio Technicians Certificate bears No. 48/1973. His motorsport radio work began in 1975. These are technical qualifications alongside decades of hands-on diagnosis, installation and problem-solving, not a claim to certify a helmet shell.

Rex works across radio selection, communications integration, fault diagnosis, servicing and relevant radio-electronics assessment. New Zealand and Australia have different radio requirements, so the exact equipment, frequencies, programming and intended event use need to be considered in the relevant country.

Race engineering experience that works in the car

Aaron Harris is a racing driver and race engineer. His experience includes the Bathurst 1000 and Bathurst 12 Hour, a first-in-class result at the Barcelona 24 Hour in 2013 and professional race-engineering work. That perspective matters when the fault only appears under race conditions, when the communications need to work around the driver, or when a car setup and alignment decision needs more than a catalogue specification.

We can help think through race-car alignment, geometry, measurement methods, equipment choice and the relationship between setup and how the car actually behaves. For the detailed methods, see our race-car alignment and setup guide. This technical-support page is the place to start when you need people who understand the problem, not just a list of tools.

Repair the failed component where practical

We service the radio and communications equipment we sell and carry small parts. A faulty microphone does not automatically require a complete replacement helmet kit; a failed connector does not automatically make an otherwise sound system disposable. We inspect the exact item and, where suitable parts and a sound repair are possible, replace the affected communications component. We can trace a fault through the radio, intercom, headset, PTT, wiring, connectors or antenna system instead of guessing.

We assess the equipment before confirming whether repair is suitable, what it will cost or how long it will take. No single repair promise fits every product or fault.

Electronics are not the helmet shell

We work on and assess relevant radio and communications electronics used with motorsport helmets. We do not certify helmets or helmet shells. Servicing or certifying relevant electronic equipment does not certify the helmet’s protective structure, its impact standard or eligibility for a particular race. Check the exact helmet label, category and event rules with the relevant organiser.

Bring us the real problem

Tell us the motorsport discipline, vehicle, radio/intercom and helmet-audio models, the symptoms, and what has already been tested. Clear photos of affected connectors and wiring help. For race-car setup, tell us the car, current measurements, handling issue and what change you are trying to achieve. Contact our technical team.

Frequently asked questions

What makes this different from buying another box?

Our radio engineering and race engineering are part of the service. We diagnose the system and the real-world use before choosing a repair, a compatible part or a replacement. The point is to put the problem right, not just make another sale.

Do I need a whole new helmet kit for a faulty microphone?

Not necessarily. We can inspect the exact kit and, where a suitable part and sound repair are available, replace the microphone rather than the whole assembly.

Can a damaged communications connector be repaired?

Often a connector can be replaced, but the wiring, compatibility and condition of the equipment must be checked first. Send us the exact model and a clear photo before we recommend a fix.

What if the radio works in the workshop but fails during racing?

Tell us when the fault happens: under engine load, with a particular driver, in a particular position or only when transmitting. We can help narrow down the radio, power, antenna, intercom, PTT, cable and connector path rather than assuming the whole system has failed.

Do you service what you sell?

Yes. We support and service the motorsport communications equipment we sell and carry small parts for suitable component-level work. Assessment comes before any promise of a particular repair.

Does Rex have formal radio qualifications?

Yes. Rex is a qualified Radio Telecommunications Engineer, an Approved Radio Certifier in New Zealand (ARC 127) and an Approved Radio Engineer (ARE). His Radio Technicians Certificate bears No. 48/1973, and he has worked in motorsport radio since 1975.

Can you certify my helmet?

No. We do not certify helmets or helmet shells. Work on communications electronics is separate from the helmet’s protective structure and event eligibility.

Are NZ and Australian radio rules the same?

No. The exact transmitting equipment, frequencies, programming, authorisations and intended use need to be checked for the relevant country and event. A system that works technically is not automatically authorised to transmit everywhere.

Can Aaron help with race-car alignment and setup?

Aaron’s racing and race-engineering background informs our alignment and setup advice, including how to approach measurements, equipment selection and handling questions. Share the car and the problem so the discussion starts with your actual setup.

Can you quote a repair before seeing the equipment?

We can discuss likely checks, but the right work and cost depend on the exact model, fault, condition and parts. We assess these before confirming a repair, price or turnaround time.
