Whiteline Front Essential Vehicle Bushing Kit - 2011-2021 Subaru STI

Address Every Front Bushing in One Purchase
The Whiteline Front Essential Kit for the 2011-2021 Subaru STI bundles the key front suspension bushing upgrades into a single, matched set. Rather than identifying each bushing individually, ordering separately, and hoping everything arrives at once, this kit gives you everything needed to refresh and upgrade the front suspension bushings on the GR/GV chassis in one shot. The polyurethane compounds are selected for each bushing location based on function -- not all bushings should be equally stiff.

DETAILS

• Covers key front suspension bushing positions for 2011-2021 Subaru STI (GR/GV chassis)
• Polyurethane compounds selected per bushing function and location
• Protective plating on all metal components for corrosion resistance
• Engineered as a matched system for balanced performance improvement
• Direct-fit -- no modifications required

Why a Kit Rather Than Individual Bushings
Front suspension bushings don't wear at the same rate or fail at the same time, but they do interact. A stiff outer bushing with a worn inner bushing produces unpredictable geometry that you can feel as vagueness and inconsistency. Doing all of them at the same time ensures the chassis responds predictably -- every bushing is contributing consistently.

Graded Compounds for Each Position
Not every bushing position on the front suspension calls for the stiffest possible compound. Control arm inner bushings need to allow controlled movement without harshness. Anti-roll bar mounts need to hold the bar firmly. Whiteline engineers each compound for its specific function, which is why their kits deliver performance improvement without the harsh ride associated with wholesale polyurethane replacement.

The GR/GV STI Platform
The 2011-2021 STI on the GR and GV chassis covers a long production run. High-mileage examples accumulate bushing wear that shows up as imprecision in turn-in, wandering on center, and inconsistency under trail braking. This kit addresses that comprehensively.

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

If your GR or GV STI has significant mileage and you're refreshing the suspension, start with this kit. It's the most efficient way to address front bushing wear and bring the chassis back to -- and beyond -- factory precision.
