What makes Whiteline different from OEM suspension components?

Whiteline suspension products are engineered for performance and durability well beyond OEM standards. While factory (OEM) components often use soft rubber bushings that degrade over time and under load, Whiteline uses advanced polyurethane and bushing technology that resists oil, heat, abrasion, and weathering. This results in sharper handling, more responsive steering, better load control, and significantly improved lifespan — without the harshness of traditional solid bushings.

Do I need a wheel alignment after installing Whiteline components?

It’s recommended to perform a wheel alignment after installation to ensure optimal performance and tire wear.

Are Whiteline Fixed Offset Upper Control Arms (UCAs) necessary for lifted vehicles?

They help maintain correct alignment and steering geometry after a vehicle is lifted.

Can I install Whiteline products myself?

Some products are DIY-friendly, but professional installation is recommended for suspension components.

Do Whiteline products come with a warranty?

Yes. Please refer to our warranty policy for details.

Description

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.
