Whiteline 20mm Front Sway Bar Mount Bushing Kit – 2002-2007 Subaru WRX (Sedan & Wagon) / 2004-2007 Subaru STI / 2003-2007 Subaru Impreza (Non-Turbo)

Whiteline 20mm Front Sway Bar Mount Bushing Kit – 2002-2007 Subaru WRX (Sedan & Wagon)

OEM-Size Replacement With Polyurethane Performance
The 20mm front sway bar mount bushing covers 2002-2007 GD WRX setups running a 20mm front bar. This polyurethane replacement eliminates the compliance of worn OEM rubber mounts, keeps the bar located correctly under cornering loads, and includes a knurled inner bore for grease retention and quiet long-term operation.

OEM Replacement With Better Material
20mm is an OEM front sway bar diameter on certain GD WRX configurations. Whiteline’s polyurethane replacement uses the same diameter and bracket fit as the OEM rubber unit, but with meaningfully less compliance under load — the bar stays put, and the anti-roll performance you have is fully utilized.

When to Replace Front Mount Bushings
Front sway bar mount bushings typically last several years before wear becomes significant. On a car with 100,000+ miles and no previous bushing service, the original rubber mounts are likely showing their age. Symptoms include clunking over bumps and a front end that feels vague compared to how it used to feel.

Sedan and Wagon
Covers both body styles of the GD WRX. Verify front bar diameter is 20mm before ordering.

The RallySport Take

The correct polyurethane replacement for 20mm front mount bushings on the GD WRX. Easy maintenance upgrade. 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.
