Whiteline Front Lower Control Arm Rear Bushing Kit (FCAB) Caster Offset +0.5° – BMW 3 Series E46 – Wishbone Rear/Lollipop Bush 66.3mm – Caster Correction Alignment Upgrade

Whiteline caster‑offset front wishbone rear bushes for BMW 3 Series E46

Transform the front end of your E46 with a precision alignment upgrade that tightens up steering feel, boosts straight‑line stability and restores confidence under braking. These Whiteline front wishbone rear bushes use an advanced synthetic elastomer that resists deflection, delivering crisp turn‑in and consistent geometry for fast road driving, daily use and track days.

Engineered for the BMW 3 Series E46 chassis, this offset FCAB set adds approximately +0.5 degree of positive caster to enhance self‑centring and high‑speed stability while helping the car track true over rough surfaces. The 66.3 mm outer diameter design suits the larger lollipop housing and replaces tired rubber components that can cause vague steering, tramlining and brake shimmy.

Why choose this suspension upgrade

• Sharper steering response and improved on‑centre feel
• Extra positive caster for better straight‑line stability and corner entry
• Reduced bushing compliance for more accurate wheel alignment under load
• Durable synthetic elastomer for long service life and consistent performance
• Ideal for performance road builds, spirited driving and track use
