Whiteline Lowering Springs Kit – 2008-2014 Subaru STI

Purpose-Built Lowering Springs for the GR/GV STI
The Whiteline lowering spring kit for the 2008-2014 Subaru STI is a direct-fit progressive-rate package developed specifically for the GR/GV STI chassis. The STI’s suspension is tuned for high-performance driving from the factory — these springs work with that calibration to lower the center of gravity and reduce body roll while maintaining the compliance needed for both street driving and track use.

DETAILS

• Progressive rate lowering springs for 2008-2014 Subaru STI (GR/GV chassis)
• Lowers center of gravity for reduced body roll
• Compatible with OEM Bilstein dampers and common aftermarket setups
• Developed at Whiteline’s Australian facility
• Direct bolt-in — no modification required

STI-Specific Calibration
The GR/GV STI uses Bilstein shock absorbers as standard equipment — a higher-specification damper than the WRX. Whiteline’s spring kit is designed with the Bilstein damper characteristics in mind, ensuring the spring rate and progressive curve work appropriately with the OEM damper specification. The result is a lowered car that still performs as a system rather than fighting its shock absorbers.

Progressive Rate for STI Dual Use
The STI is frequently used as a daily driver that also sees track days. Progressive rate springs accommodate both requirements — comfortable over normal road surfaces, appropriately stiff under the cornering loads of track driving. The progressive design avoids the harshness associated with fixed-rate lowering springs.

Foundation for Complete Suspension Development
Springs set the foundation. For the most complete STI suspension improvement, pair these with Whiteline’s BSF48Z/BSF39Z front bar, BSR49 series rear bars, and KCA325/KCA326 rear camber adjustment bushings. All are designed for the GR/GV chassis as a system.

Why Choose Whiteline

Whiteline has been engineering suspension components from their facility in Australia since 1979. Every product in their catalog is developed with a clear goal: measurable improvement in handling, stability, and tyre contact. Whiteline’s polyurethane bushings, sway bars, control arms, and alignment correction kits are engineered using finite element analysis and validated on track before they reach the market. Their components are direct-fit, bolt-on solutions designed for enthusiasts who want real performance gains without fabrication or custom work.

The RallySport Take

The correct lowering spring for the GR/GV STI. Whiteline’s STI-specific calibration ensures compatibility with the factory Bilstein dampers and maintains the performance character the car was designed to deliver. Get an alignment after installation — lowering changes geometry and the car won’t handle correctly without a proper four-wheel alignment at the new ride height. Combine with Whiteline’s roll center correction kit if the car uses MacPherson strut front suspension.
