Whiteline's Anti Geometry Kit replaces the front control arm rear vertically mounted bushing and featuring low compliance synthetic elastomer with high performance/low compliance bearings for optimum dynamic alignment. Positive static caster gains can also be achieved by the offset orientation of the bearing and unique to any Whiteline Anti geometry kit before it, KCA425 allows WRX and STI owners to tune geometry from Anti Lift to Anti Dive via a combination of recommended spacers delivering a window of handling behaviour and vehicle set up for the driver's needs.
Whiteline Control arm - lower inner rear bushing.
Protective plating on all metal components acts as a hard skin that is much tougher than conventional paint allowing this product to withstand the toughest conditions and resist corrosion for years to come.
Featuring premium anodized alloy materials, Whiteline alloy products are anodized providing a long-lasting protective barrier to corrosion and wear but they look great too.
Engineered to alter/ optimise caster alignment to maximize tyre contact patch during roll, improve turn-in response & increase directional stability.
Whiteline's latest technology synthetic elastomer formulation boasts resistance to oil, grease, ozone and weathering.
Engineered to alter/ eliminate unwanted bump steer, optimising the vehicles steering characteristics.
Install guide included providing detailed instructions on how to install your new Whiteline purchase.
Specially bonded design for optimised strength typically required in high load bearing applications.
Upgrade your Subaru WRX or STI with the Whiteline KCA425 front control arm lower inner rear bushing kit, engineered to improve handling and steering precision. This kit replaces the factory rear control arm bushings with high-performance synthetic elastomer components that resist oil, grease, ozone, and weathering, ensuring long-lasting durability in demanding driving conditions. The protective plating on all metal parts provides a tough barrier against corrosion, extending the lifespan of the components and maintaining optimal performance over time. Crafted from premium anodized alloy, the Whiteline alloy parts combine durability with an attractive finish, adding a sleek appearance to your vehicle's suspension system. These bushings are designed to alter or optimize caster alignment, maximizing tire contact during roll and enhancing turn-in response for sharper handling. The kit also helps eliminate unwanted bump steer, resulting in more predictable steering characteristics and increased vehicle stability. The Whiteline KCA425 kit offers a unique adjustable feature, allowing drivers to tune their vehicle's geometry from anti-lift to anti-dive settings. This flexibility is achieved through a combination of recommended spacers, providing a customizable handling window tailored to the driver’s preferences and driving conditions. The installation guide included ensures proper setup, making it accessible for both enthusiasts and professional mechanics. The specially bonded design of the bushings provides enhanced strength, particularly suited for high load-bearing applications, ensuring that performance is not compromised under aggressive driving. Whether you're looking to improve daily driving comfort, track performance, or overall vehicle stability, the Whiteline KCA425 kit offers a comprehensive solution to optimize your Subaru's suspension geometry and handling characteristics.
