Chassis Systems & Fabrication

At Superformance, we source, supply and customise chassis for major American platforms, including classic muscle cars, street rods and performance build applications. Whether you need a direct-fit replacement, a modernised performance chassis, or a full ground-up custom design, our workshop is equipped to source, engineer, fabricate, and/or install to the highest standards.

Why You Need a New or Upgraded Chassis

Structural Fatigue & Age-Related Deterioration

Over time, OEM chassis components suffer from rust, metal fatigue and distortion, especially in classic American vehicles. A compromised chassis reduces rigidity, alignment accuracy and safety. Replacement ensures a structurally sound foundation that meets modern load, torque and suspension demands.

Increased Power & Torque Loads

Modern engines like an LS, small block, big block or high-performance crate packages, produce significantly more power than original factory equipment was ever designed to handle. Upgrading to a precision-engineered, high-torsional-rigidity chassis eliminates chassis flex, protects driveline geometry, and allows safe, reliable integration of high horsepower components.

Modern Handling & Ride Quality

A high-quality chassis provides:

• improved weight distribution

• enhanced suspension mounting accuracy

• upgraded crossmember integration

• better caster/camber stability

• reduced body roll

Drivers benefit from sharper handling, improved road feel, and higher-speed stability—critical for performance builds, touring cars, and custom street machines.

Why Quality Matters

High-quality chassis systems are built to exact tolerances. This ensures correct drivetrain alignment, predictable suspension geometry and improved steering response. Poorly engineered chassis compromise safety, drivability and long-term reliability.

We only supply chassis built from certified structural-grade steel with reinforced bracing, gusseting and TIG/MIG weld integrity. Inferior materials can distort under load, crack at stress points, or fail under high torque.

Full Custom Chassis Fabrication Brisbane

For unique builds, unusual drivetrains, 4-link rear conversions, heavy-duty applications or show-car level fabrication, our team can build a complete custom chassis from the ground up.

Custom fabrication includes:

• bespoke frame rails

• crossmembers engineered for modern transmissions

• 4-link, 3-link or IRS integration

• adjustable coilover mounting points

• custom engine and gearbox mounts

• rack and pinion steering integration

• brake and fuel line routing solutions

Every build is CAD-designed, fabricated in-house, and individually test-fitted to ensure perfect accuracy.

Our workshop provides complete installation and setup, including:

• chassis swaps

• engine/transmission alignment

• suspension calibration

• brake system integration

• steering rack installation

• fuel and brake line routing

• driveline angle measurement

Every installation is completed to performance and safety standards for long-term reliability.
