Subaru WRX STI Suspension Lift Kit - Front - Whiteline - Race Anti-Dive Caster Kit - Stealth Black - `11-`27. A motorsport-only front geometry kit for 2011+ WRX STI (excludes WRX) that tightens response and stability during aggressive driving.

Whiteline KCA425M replaces the front control arm rear, vertically mounted bushing with a lightweight anodized alloy housing and high-performance, low-compliance bearings. The double-offset design delivers positive static caster gains, while included spacer combinations let you tune behavior from anti-lift to anti-dive to match track, vehicle setup, and driver preference. Stealth Black finish, articulation voids for proper movement, and a detailed install guide round out a precise, durable package engineered for dynamic alignment control and confident turn-in.
