Heritage Series Front Sway Bar Bushing 30.8 Mm - E46 M3

Product Details

Lock Down the Apex: Heritage Series 30.8mm CSL Sway Bar Bushings

Body roll translation delay is a direct threat to mid-corner balance and corner-exit speeds. Under heavy lateral loads, original equipment rubber bushings flex and squash within their brackets, allowing the front sway bar to rotate off-axis before it actually begins to resist body roll. The Powerflex PFF5-4602-30.8H Bushing Set eliminates this compliance on E46 M3 models equipped with the upgraded 30.8mm M3 CSL front anti-roll bar.

By utilizing Powerflex’s street-spec durometer curves cast in their discrete Heritage Collection dark grey finish, these bushings offer zero-compromise geometry control. They significantly reduce stiction and eliminate bracket-side deflection under heavy load, ensuring your high-rate CSL bar transfers torsional load immediately to the opposite wheel. This is the ultimate engineering upgrade for purists looking to sharpen front-axle bite while preserving a clean, stock undercarriage.

Technical Features:

• 30.8mm Precision Bore: Tailored specifically for the factory E46 M3 CSL front anti-roll bar (OE Part # 31352282656).

• Eliminated Torsional Lag: Forces the sway bar to activate instantaneously under heavy cornering loads.

• Internal Lubrication Channels: Knurled inner bore retains grease to ensure smooth, squeak-free bar rotation.

• Advanced Polyurethane Compounding: Outlasts standard rubber by resisting dry-rot, extreme track-side brake heat, and petroleum degradation.
