Answer First — Why Choosing the Right Conversion Matters
If you’re importing a JDM car or any left-hand-drive (LHD) vehicle into Australia, a proper conversion to right-hand-drive (RHD) is crucial for safety, legal compliance, and resale value. A poorly executed conversion can lead to:
-
Failed registration or compliance checks
-
Unsafe driving conditions
-
Expensive post-conversion fixes
-
Reduced resale value
This blog will guide you through what to look for in a conversion, the costs, and best practices to make your LHD-to-RHD project smooth and compliant.
1. Understand Australian Regulations Before You Start
Australia has strict rules regarding LHD-to-RHD conversions:
-
State Compliance: Each state has specific roadworthy and compliance standards. For example:
-
NSW: Roads & Maritime Services (RMS) requires engineer certification and safety compliance.
-
Victoria: VicRoads demands a Vehicle Standards Compliance Certificate and inspection for modified vehicles.
-
-
Age & Vehicle Type Restrictions: Some older vehicles (classic cars) have exemptions, but modern cars must meet full ADR (Australian Design Rules) standards.
-
Safety Requirements: Brake systems, lighting, seat belts, steering alignment, and ADAS features must all function correctly post-conversion.
Tip: Before importing, check your state’s guidelines on RHD conversions to avoid surprises.

2. Know the Types of LHD-to-RHD Conversions
Not all conversions are equal. The main types include:
a) Full OEM Conversion
-
Uses factory RHD parts (steering column, dash, pedals).
-
Maintains original vehicle integrity.
-
Usually the safest and most reliable.
-
Most expensive option.
b) Custom Conversion
-
Fabricated steering assemblies, dash modifications, and relocated pedals.
-
Flexible for rare or discontinued models.
-
Requires expert engineering to meet compliance.
-
Moderate to high cost; riskier if done by inexperienced workshops.
c) Partial Conversion / Hybrid Approach
-
Converts only the steering and pedal setup.
-
Retains LHD dashboard with minor modifications.
-
Can be cheaper but may limit resale value and comfort.
Key Insight: Choosing the right type depends on your vehicle model, intended use, and budget.
3. Evaluate the Expertise of the Conversion Workshop
A high-quality conversion depends entirely on the skills and reputation of the workshop:
-
Experience with JDM cars: Japanese models often have unique steering, braking, and ADAS systems.
-
Engineering Certification: Ensure the workshop provides a roadworthy engineer’s report for your state.
-
Track Record: Ask for references, before-and-after photos, and case studies.
-
ADAS / Modern Safety Systems Handling: If your car has cameras, radar, or lane-keeping assist, the workshop should recalibrate them after conversion.
Tip: Avoid workshops without proven compliance experience, especially for modern or tech-heavy JDM imports.
4. Check Compatibility of Key Vehicle Systems
Not all vehicles convert easily. Before committing, consider:
-
Steering Column & Rack Compatibility: Some modern cars require specially fabricated racks.
-
Brake & Clutch Linkages: Must be moved or adapted for RHD compliance.
-
Dashboard & Instrument Cluster: Some vehicles’ electronics don’t function if relocated incorrectly.
-
ADAS / Sensors / Lane Assist: Many advanced JDM models need recalibration post-conversion.
-
HVAC, Pedals, and Wiring Harnesses: Overlooked details can cause failures or non-compliance.
5. Understand Costs and Budgeting
LHD-to-RHD conversions vary widely based on vehicle age, complexity, and desired quality:
| Conversion Type | Typical Cost (AUD) | Notes |
|---|---|---|
| Full OEM Conversion | $15,000–$30,000+ | Most expensive but safest, high resale value |
| Custom Conversion | $10,000–$20,000 | Good for rare JDM imports, requires certified workshop |
| Partial / Hybrid | $5,000–$12,000 | Quick and cheaper, may affect resale value |
Additional Costs to Consider:
-
ADAS recalibration ($500–$2,000)
-
Vehicle compliance certification ($200–$800)
-
RWC inspection / state registration fees ($100–$600)
Pro Tip: Always budget 20–30% above quoted price to cover unforeseen complications.
6. Timeline and Project Planning
Conversions are not instant. Typical timelines:
-
Full OEM Conversion: 6–12 weeks
-
Custom Conversion: 4–8 weeks
-
Partial Conversion: 2–4 weeks
Delays often occur due to importing specific RHD parts from Japan or engineer certification backlog. Planning early is critical.
7. How to Maximise Safety and Legal Compliance
-
Hire accredited engineers for all structural and steering changes.
-
Document everything: photos, part numbers, invoices, recalibration logs.
-
Keep ADAS systems intact: modern safety tech must be functional after conversion.
-
Choose workshops familiar with Australian ADRs and your state’s RHD regulations.
-
Use a project checklist to ensure nothing is overlooked before inspection and registration.
8. Choosing the Right Conversion for Your JDM Import
Consider:
-
Vehicle type and rarity: Rare JDMs may require custom conversions.
-
Budget: Full OEM conversions cost more but retain value.
-
Safety features: Modern ADAS-equipped cars need expert handling.
-
Resale value: High-quality conversions retain or increase resale price.
-
Timeframe: Allow sufficient time for parts sourcing, workshop work, and inspections.
Bottom line: Investing in a professional, certified, and experienced workshop is essential to protect your investment and ensure legal compliance.

Conclusion
LHD-to-RHD conversions for Australia are complex but manageable with the right approach.
-
Understand state regulations (NSW vs Victoria, or other states).
-
Choose the conversion type wisely (OEM vs custom vs partial).
-
Hire experienced, certified workshops.
-
Factor in ADAS recalibration and other safety tech costs.
-
Document everything for compliance and registration.
A high-quality conversion ensures your imported JDM car is safe, road-legal, and retains its value, letting you enjoy your dream car with confidence.
