BMW F22 / F30 / F32 Rear Sway Bar Bushings - 15mm

Product Details

In high-stakes motorsport and aggressive track applications, consistency equals speed. The factory rubber anti-roll bar bushings equipped on the BMW F2X 2-Series and F3X 3/4-Series chassis are a critical weak point in the suspension geometry. Under high lateral loads, OEM rubber deflects significantly. This delay in anti-roll bar rate engagement introduces unwanted body roll, compromises the tire contact patch, and creates a vague, unpredictable transition at the limit.

The Powerflex Black Series Rear Anti-Roll Bar Bushing is designed to eliminate compliance entirely. Manufactured from Powerflex’s proprietary 95 Shore A polyurethane compound, this upgrade delivers near-zero deflection, ensuring immediate rear stabilization and precise chassis rotation the moment you initiate turn-in.

Technical Performance Benefits

• Instantaneous Sway Bar Rate Engagement: By replacing compliant rubber with ultra-high-durometer polyurethane, lateral forces are transferred directly into the anti-roll bar without delay.

• Optimized Tire Contact Patch: Reducing compliance stabilizes the rear suspension geometry under hard cornering, maintaining maximum mechanical grip across the rear axle.

• Race-Proven Durability: Engineered to withstand the extreme thermal and mechanical stresses of endurance racing, time attack, and high-ambient track days. This compound resists degradation from heat, oils, and track-surface contaminants.

• Low-Friction Internal Grooving: Knurled internal bores retain specialized lubricant, preventing binding and ensuring smooth, predictable articulation throughout the suspension stroke.

Fitment Note: We recommend measuring your rear factory or aftermarket sway bar to determine which size of bushings are required for your vehicle. Sway bar sizes can differ depending on factory suspension packages and aftermarket sway bar brands.
