Important Things to Consider Before Implementing Car Modifications

If you want to modify your car, you have to know that it involves adherence to different national and state-specific regulations. This is to ensure that your vehicle stays safe, legal, and roadworthy. Note that Australia has strict laws in terms of vehicle modifications because it is intended to maintain road safety and environmental standards. Thus, understanding the requirements before starting any modifications is essential.

State-Specific Laws and Engineering Certification

There are varying rules by state and territory, so you have to consult a relevant authority on the basis of your location. These authorities may provide guidelines on what  type of car modification you are allowed to apply for and how to get necessary certifications.

There are also modifications that may require an engineering certification to confirm that the changes will meet the Australian design rules and safety standards. This is also specific in each state of the country, particularly in New South Wales and Victoria. These certifications are applicable to significant structural or performance modifications, which include engine swaps, suspension changes, and turbocharging.

Types of Modifications and Requirements

  • Engine modifications

If you are going to apply small upgrades, you might not need a certification for that. These may include exhaust or intake modifications. However, if you add supercharger, turbocharger, or a different engine to your car, it usually requires an engineer’s inspection and certification. So, if the engine’s capacity increases beyond the limit in a particular state, you might not be able to use it on the road without proper certification.

  • Suspension modifications

If you raise or lower your car, it has specific restrictions that you need to consider. For example, most states will have a limit to a change in height of 50mm or 5cm from the factory specification without certification. Therefore, any extreme suspension work will typically require engineering approval.

  • Wheels and tyres

If you are going to modify the wheel and tyre, you need to stay within certain limits to keep it legal. So, it should be no more than two inches larger in diameter or width compared to the stock wheel size. Moreover, tyres must be able to meet the load and speed ratings that should be appropriate for the vehicle.

  • Interior modifications

The use of racing seats or seat belts will require certification because they can impact safety. In terms of the steering wheel, it must comply with the airbag requirements. This is essential in vehicles where airbags are a standard safety feature.

Emission Compliance Certification

If you are going to consider modifications that will affect emissions, then it must comply with Australian emissions standards. These include engine swaps or exhaust changes that may involve catalytic converters and the overall emissions output of the vehicle. Thus, it is illegal to remove or tamper with the emissions control equipment, such as the catalytic converter.

Aesthetic Car Modifications 

Generally, aesthetic modifications to your car may not require certification as long as they don’t affect the car’s visibility, structure, and safety. Such may include the use of  stylish car floor mats, body kits and spoilers, or vinyl wraps and paint jobs, among others. There are a few exceptions though and specific guidelines that you should be aware of because even aesthetic modifications may sometimes affect the roadworthiness or compliance with state regulations.
