Turning your everyday car into a street-legal race machine is every car enthusiast’s dream. But blending performance with road compliance requires careful planning and precise modifications. At Elden’s Autobahn (EA) Performance, we’ve helped many drivers transform their vehicles into street-legal race cars that balance track performance with everyday usability. Here’s our guide to the essential steps and modifications needed to build a street-legal race car.
Step 1: Understand the Rules and Regulations
Before diving into the modifications, you’ll need to familiarise yourself with local road compliance rules. In Australia, street-legal modifications must comply with Australian Design Rules (ADRs) and state-specific regulations. Non-compliant mods can lead to hefty fines or your car being taken off the road.
Key Areas to Consider
- Noise Levels: Performance exhausts like those from Capristo must meet local decibel limits.
- Emissions Compliance: Your car must pass emission standards, so ensure your upgrades don’t cause compliance issues.
- Safety Standards: Features like proper lighting, road-worthy tyres, and functioning safety systems are non-negotiable.
Contact Elden’s Autobahn for advice on road-compliant modifications.
Step 2: Upgrade the Engine for Power and Reliability
A race car needs power, but reliability is just as important for street driving. Upgrading your engine’s performance is a delicate balance between raw power and practicality.
Recommended Engine Mods
- ECU Tuning: Optimise your engine’s output with tuning options like those from DMS Automotive.
- Forced Induction: Consider turbochargers or superchargers from VF Engineering for a power boost.
- Improved Air Intake: Aftermarket air intakes enhance airflow for better combustion.

Step 3: Focus on Suspension and Handling
A great race car doesn’t just go fast—it handles well too. Suspension upgrades are critical for ensuring your car stays planted through corners and remains comfortable for street use.
Suspension Mods
- Coilovers: Adjustable coilovers from KW Suspensions offer customisable ride height and damping.
- Performance Bushings: Polyurethane bushings improve stability and feedback.
- Anti-Roll Bars: Reduce body roll for sharper handling.

Step 4: Install High-Performance Tyres and Wheels
Tyres are your car’s connection to the road, and choosing the right set is essential for both grip and road compliance. Pairing performance tyres with lightweight wheels maximises handling and acceleration.
Recommended Options
- Tyres: Racing tyres from TNEER or all-rounders for dual-use.
- Wheels: Lightweight forged wheels from Brixton Forged reduce unsprung weight for better handling.

Step 5: Enhance the Exhaust System
A performance exhaust system not only adds power but also delivers that exhilarating sound every race car deserves. However, it must remain within noise and emissions limits for street use.
Top Exhaust Brands
- IPE: Delivers a powerful sound and improved flow.
- Capristo: Offers systems designed for both performance and compliance.

Step 6: Boost Safety Features
Safety is paramount when you’re building a street-legal race car. Upgrading safety features ensures your car is protected on the track and complies with road safety standards.
Essential Safety Upgrades
- Brakes: High-performance brake systems like those from RacingLine provide reliable stopping power.
- Roll Cages: Ensure your cage is ADR-compliant for added safety.
- Harnesses and Seats: Race-style seats and harnesses improve driver safety and control.
Step 7: Final Touches for Aesthetics and Aerodynamics
Looks matter too! Body kits and spoilers enhance your car’s appearance while improving aerodynamics. Just make sure they’re road-compliant and don’t hinder visibility.
