STI Performance | The Pinnacle of Subaru Technical Engineering
Factory-engineered precision for the ultimate balanced driving experience. At Chicane Australia, we provide specialised supply for STI (Subaru Tecnica International). Unlike generic aftermarket brands, STI hardware is developed under the "Total Tuning" concept, focusing on improving the vehicle's overall character rather than just peak numbers. We facilitate fast sourcing and reliable delivery across Australia for their flagship range of flexible chassis braces, Group N competition mounts, and aerodynamic enhancers.
The STI 'Flexible' Philosophy & Group N Heritage
STI is world-renowned for their patented Flexible Tower Bar and Draw Stiffener technology. Unlike a rigid bar that can make a car feel nervous on uneven surfaces, STI’s flexible components utilise a ball-jointed longitudinal link. This allows the chassis to remain supple over bumps while providing instantaneous lateral rigidity during turn-in. For those seeking a more connected drivetrain, their Group N hardened rubber mounts are the global standard, significantly reducing engine and transmission pitch for more precise gear changes and throttle response without the extreme vibration of solid mounts.
Our sourcing capabilities cover the flagship STI Performance range:
• Flexible Chassis Bracing: The definitive handling upgrade for the WRX (VB/VA) and BRZ (ZD8/ZC6), including Flexible Tower Bars and Draw Stiffeners.
• Group N Competition Mounts: Hardened rubber engine, transmission, and pitch-stop mounts designed for WRX STI (GDB/GRB/VAB) motorsport applications.
• Short Throw Shifters: Factory-engineered linkage assemblies that reduce shift throw by up to 25%, essential for the Subaru BRZ and WRX manual gearboxes.
• Aerodynamic Enhancers: Wind-tunnel tested front under spoilers, side skirts, and rear diffusers that provide genuine downforce and stability at high speeds.
Based on the Central Coast, NSW, we provide the technical expertise to ensure your STI components are correctly matched to your vehicle’s year and model. We work closely with our supply network to ensure your authentic Japanese-engineered hardware is sourced and despatched with professional care and speed.
STI Performance FAQ
What is the benefit of an STI 'Flexible' Tower Bar?
A standard rigid bar can sometimes make the car feel 'twitchy' as it forces the suspension towers to move together. The STI Flexible Tower Bar features a central pillow ball joint; it provides rigid support against lateral forces (cornering) while allowing a small amount of vertical flex to absorb road shocks, resulting in a more 'planted' and comfortable driving feel.
Are STI Group N mounts too harsh for a street car?
STI Group N mounts use a higher-durometer rubber than factory mounts. While they do transmit slightly more noise and vibration (NVH) than stock, they are significantly more refined than polyurethane or solid mounts, making them the perfect 'OEM-plus' choice for a spirited street or track-day Subaru.
How quickly can you source STI products?
We utilise a robust international and local supply network to provide the fastest possible turnaround. Most STI Performance chassis, drivetrain, and interior components for Australian models are sourced and despatched within a short timeframe for delivery nationwide.
