Expert Motorsport Advice

Need Help Choosing The Right Equipment?

Talk directly with experienced motorsport professionals. Whether you're setting up a race car, selecting a race radio system, choosing a helmet, or building a complete communications package — we can help.

Harris Race Radios is not a general sporting goods retailer. Every person you speak with has real, active motorsport experience at professional level. That's a rare thing in motorsport retail anywhere in Australasia.

Areas We Can Help With

Race Helmets & Safety Equipment

  • Which helmet standard you need — SA2020, SA2025, FIA 8859, 8860, or discipline-specific requirements
  • MSNZ and Motorsport Australia compliance — what's accepted at scrutineering, what's not
  • Helmet brand and model selection — Stilo, Bell, Schuberth, OMP, Roux, and more
  • FHR / HANS device compatibility and fitting
  • Racewear selection — suits, gloves, boots, and HANS to match your licence requirements
  • Visor tear-offs — fitment by helmet model for speedway, dirt track, and open cockpit motorsport

Race Radios & Intercom Systems

  • In-car intercom systems — driver to co-driver, driver to crew, full multi-position setups
  • Race radios — handheld, in-car, and pit-to-crew frequency planning and compliance
  • Headset and helmet speaker selection — OTH, in-helmet, noise cancellation, PTT wiring
  • Speedway receiver systems — hire vs purchase, frequency allocation, track compliance
  • Rally communications — co-driver intercom, pace note audio, service crew radio networks
  • Radio licensing and legal compliance for NZ (RSM) and Australia (ACMA) — Rex Harris is a certified Radio Certifier for both

Race Car Setup & Alignment

  • Four-wheel alignment methodology — string lines, hub stands, slip plates, camber gauges
  • Which B-G Racing tools suit your car and discipline
  • Setup processes for circuit, endurance, rally, and track day use
  • Interpreting alignment data — toe, camber, castor, thrust angle
  • Building a complete DIY setup kit from scratch vs starting with the essentials

Data Logging & Lap Timing

  • AiM dash loggers and GPS systems — which unit suits your car, series, and budget
  • Channel setup and sensor selection — what to measure and why
  • MyLaps transponders — TR2 vs X2, hire vs purchase, timing system compatibility
  • Alfano lap timers — karting and entry-level circuit use

Driver Comfort & Performance

  • Driver cooling systems — Chillout Systems selection, sizing for your cockpit and race duration
  • Neck collars and head restraints — what's required vs what's recommended
  • Seat and harness compatibility advice

Not Sure Where To Start?

Tell us your discipline, your car, your current setup, and your budget — and we'll tell you what we'd actually recommend and why. No sales pressure. Just straight advice from people who race.

Why Ask Us?

Most motorsport retailers can tell you what's in stock. We can tell you what actually works — because we use it ourselves at professional motorsport level.
