Whiteline KCA434 Front Anti-Dive/Caster Control Arm Lower Inner Front Bushing - Select 2013-2026 Subaru BRZ, Scion FR-S, & Toyota 86/GR86

Fits select 2013-2026 Subaru BRZ, Scion FR-S, Toyota 86, and Toyota GR86.

The Whiteline KCA434 Anti-Dive/Caster Kit is engineered to increase positive caster and optimize front anti-dive geometry. By replacing the factory control arm lower inner front bushings with low-compliance synthetic elastomer, this kit minimizes dynamic caster loss during heavy braking and aggressive cornering. The result is sharper turn-in response, increased directional stability, and more consistent alignment angles for a maximized tire contact patch.

Built for durability in high-load applications, these bushings feature a specially bonded design and internal grease reservoirs for self-lubrication. The metal components are protected by a combination of powder coating, protective plating, and anodized finishes to resist corrosion and wear in harsh environmental conditions.

• Optimized Geometry: Increases caster and reduces front-end lift and dive under load.
• Synthetic Elastomer: Proprietary formulation resistant to oil, grease, ozone, and weathering.
• Constant Lubrication: Internal grease reservoirs and supplied molybdenum disulphide (LM) grease manage friction and extend component life.
• Corrosion Resistance: Protective plating and anodized alloy materials ensure longevity against road debris and chemicals.
• Manufacturer Part Number: KCA434
