PowerFlex Steet Series Rear Beam Mount Bushing - E10

Product Details

In vintage motorsport applications utilizing the BMW 02-Series chassis the rear axle carrier (rear beam) is a critical junction for handling stability. The factory-original rubber compliance mounts are a documented failure point under racing loads. Deflection at the rear beam distorts suspension geometry during high-G cornering, induces dynamic toe and camber changes, and precipitates wheel hop under hard acceleration or braking.

The Powerflex engineering solution completely replaces the compliant OEM rubber mounts with a high-durometer, engineered polyurethane assembly. This upgrade locks down the rear subframe to the unibody, stabilizing the rear suspension geometry and ensuring predictable, repeatable tire contact patches under track conditions.

Engineering & Performance Benefits

• Elimination of Dynamic Geometry Shift: By minimizing lateral and vertical deflection of the rear beam, this kit maintains strict control over static alignment settings, providing flat, predictable tracking through high-speed sweeps.

• Optimized Power Delivery: Solidifies the drivetrain-to-chassis interface, reducing energy loss and eliminating wheel hop during hard standing starts or corner exits.

• Advanced Material Science: Formulated from proprietary polyurethane compounds that resist degradation from petroleum products, track grime, ozone, and extreme thermal cycles.

• Two-Piece Design: Engineered for straightforward installation and precise fitment within the factory carrier housings without requiring specialized hydraulic press tooling.
