BMW E60 5-Series, E63 6-Series Rear Sway Bar Bushings - 14.5 Mm

Product Details

In professional motorsport, body roll and delayed chassis response are the enemies of low lap times. The Powerflex Black Series Rear Sway Bar Bushings are engineered specifically for track, rally, and high-performance race applications where maximum chassis control is non-negotiable.

Factory rubber bushings deflect under heavy cornering loads, causing unpredictable alignment changes and a vague rear-end feel. The Black Series upgrades utilize a specialized 95 Shore A polyurethane compound, delivering up to 80% more resistance to load than standard rubber. This ensures your 14.5mm rear anti-roll bar deflects exactly when and how it was designed to, keeping the rear tires planted and maximizing mid-corner stability.

Performance Benefits

• Instantaneous Anti-Roll Bar Response: Eliminates the "slop" and delay in the rear suspension, providing immediate chassis rotation upon turn-in.

• Optimized Tire Contact Patch: By minimizing unwanted dynamic deflection, the rear suspension maintains its engineered geometry under extreme lateral G-forces.

• Engineered for Competition: Designed to withstand the punishing heat, oil, and structural stress of endurance racing and track-day environments.

• Advanced Lubricant Retention: Features internal knurling and dual-radius grooving to hold specialized polyurethane grease, ensuring smooth, noise-free operation without binding.

Powerflex Black Series components are specialized motorsport upgrades. Because they prioritize maximum deflection resistance and precise geometry retention, an increase in NVH (Noise, Vibration, and Harshness) should be expected over factory rubber. Recommended for dedicated track cars, time attack builds, and drivers demanding ultimate chassis feedback.
