Whiteline 18mm Front Sway Bar Mount Bushing Kit – 2002-2007 Subaru WRX (Sedan & Wagon)

Smallest Common Front Bar Size, Correct Fit
For 2002-2007 GD WRX configurations running an 18mm front sway bar, this Whiteline polyurethane mount bushing is the exact-fit replacement. Correct diameter, polyurethane compound, knurled inner bore — everything the same as the larger sizes in the range, sized correctly for an 18mm bar.

DETAILS

• 18mm front sway bar mount bushing for 2002-2007 Subaru WRX (sedan and wagon)
• Whiteline polyurethane compound
• Knurled inner bore retains grease
• Direct-fit to OEM front mount bracket
• Limited Lifetime Warranty

Full Size Range Covered
18mm is the smallest standard front sway bar mount bushing in Whiteline’s GD WRX range. It covers stock 18mm OEM configurations or custom setups using an 18mm bar for light front roll stiffness. The same engineering principles apply — correct size, polyurethane compound, knurled bore.

When Smaller Diameter Makes Sense
Not every WRX build calls for a large-diameter front bar. For builds prioritizing rear traction or a balance that leans toward understeer for track work, a smaller front bar with a larger rear bar is a valid setup. Whiteline carries every bushing size to support any combination.

Sedan and Wagon, GD Chassis
Fits both body styles. Confirm bar diameter is 18mm before ordering.

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

All the engineering of the larger Whiteline mount bushings in the correct size for an 18mm front bar. Get the right diameter. Installation is a straightforward bar swap — remove the OEM bar, install the Whiteline unit with the provided polyurethane mount bushings, connect the endlinks. Start in the middle adjustment position and move from there. Adjustable endlinks are a worthwhile companion purchase if the car has been lowered, ensuring the bar operates at zero preload at the new ride height.
