Whiteline Motorsport anti‑geometry front control arm kit for 2011 Subaru WRX STI replaces the rear vertically mounted control arm bushing with a lightweight anodized alloy housing and low‑compliance bearings to maintain dynamic alignment under race loads. The kit lets owners tune from anti‑lift to anti‑dive via spacer combinations, improving turn‑in response, directional stability and tyre contact during aggressive driving.
