BMW 80A Polyurethane Rear Subframe Bushing & Chassis Reinforcement Plate Kit – Improves Rear End Stability, Reduces Subframe Movement & Sharpens Handling – E46 3 Series | Replaces Part No. 33316770781, 33316770783, 33316770784

Upgrade the handling, stability, and structural integrity of your BMW E46 with this performance-focused 80A polyurethane rear subframe bushing and chassis reinforcement plate kit. Designed to replace the factory rubber subframe bushings while reinforcing the E46’s known rear subframe mounting weak points, this kit helps reduce unwanted chassis flex, improve suspension response, and deliver a more connected driving experience.

The BMW E46 chassis is well known for rear subframe mounting point fatigue and cracking, especially on higher-mileage vehicles or under aggressive driving conditions. Worn factory bushings can also contribute to excessive rear-end movement, drivetrain slop, wheel hop, unstable handling, and reduced driver confidence. This upgraded solution combines durable 80A polyurethane bushings with reinforcement plates to help strengthen the rear subframe mounting area and improve overall chassis rigidity.

Manufactured from high-quality performance-grade polyurethane, these bushings offer significantly improved durability over factory rubber while still maintaining reasonable ride comfort for both street and performance use. The included reinforcement plates add critical structural support to help protect against subframe mounting point failure.

Whether you are restoring an aging E46, preparing for spirited driving, or building a more track-focused car, this complete kit helps improve handling precision, drivetrain response, and long-term chassis reliability.

Designed for direct-fit installation.
