Product Description

The **Whiteline KCA334** kit is engineered to add **+0.5° static positive caster** and introduce anti-lift geometry to the front suspension of selected Subaru models spanning from 2003 through 2014. By replacing the rear inner rear bushings of the front lower control arms with offset housings and low-compliance polyurethane bushings, this kit sharpens initial turn-in response, enhances traction under load, and significantly reduces understeer by preserving alignment characteristics through cornering.

Ideal for lowered or alignment-sensitive vehicles, KCA334 uses an internal grease reservoir design to deliver consistent performance and minimal maintenance. Installation typically takes **2-3 hours** with removal of front lower control arms and professional wheel alignment. Platform-specific instructions must be followed carefully to orient the eccentric bushings correctly (hole placement towards centreline yields maximum caster gain).

Compatibility is confirmed across **Subaru Impreza (WRX/STI & base), Forester SH, XV/Crosstrek, Legacy/Outback BP, and Tribeca B9 models** within the stated years. Fitment beyond 2014 or on newer chassis is unverified at time of listing. Whiteline backs this kit with a **3-year / 60,000 mi (≈ 100,000 km)** warranty. This product does not affect emissions compliance.
