Bevinsee 80A Poly Rear Subframe Bushing Kit — E46 / E83
by Bevinsee
Key Features
- 80 Shore A polyurethane construction — firmer than rubber OEM, street-friendly hardness
- Maintains consistent rear suspension geometry, especially critical on lowered E46s
- Reduces subframe flex for sharper throttle response and improved drivetrain stiffness
- Corrects toe geometry by raising subframe, compensating for lowered roll center
- Low NVH increase versus harder poly options — viable for daily-driven BMWs
- Direct OEM replacement for part numbers 33316770781, 33316770783, 33316770784, and more

Bevinsee 80A Poly Rear Subframe Bushing Kit — E46 / E83 — Overview
The rear subframe bushings on an aging E46 or E83 X3 are among the first components to go soft, and worn rubber units rob the chassis of the precise, connected feel these cars were engineered to deliver. Bevinsee's 80A polyurethane rear subframe bushing kit is a direct OEM replacement that restores — and meaningfully improves — how the rear end behaves under real driving conditions. At 80 Shore A, the compound is significantly stiffer than factory rubber without crossing into the harsh, street-punishing territory of race-spec bushings.
The practical benefits are felt immediately behind the wheel. Reduced subframe movement keeps rear toe geometry consistent through cornering and hard acceleration, tightening up the rear end and giving the chassis that crisp, planted character the E46 platform is known for. On lowered cars, this upgrade carries extra importance: the raised subframe position helps correct roll center geometry that can otherwise introduce unpredictable handling behavior at the limits. Drivetrain inputs feel more direct, and the rear end tracks more faithfully through corners.
Fitment covers the complete E46 range — 323i, 323Ci, 325i, 325Ci, 325xi, 328i, 328Ci, 330i, 330xi, and 330Ci — as well as the E83 X3, replacing OEM part numbers including 33316770781, 33316770783, 33316770784, 33311092517, 33316757394, and 33316757393. Note: the E46 M3 is not compatible. As with all polyurethane bushings, proper greasing with a poly-compatible lubricant during installation is essential — skip this step and you risk squeaking and premature wear. Do it right once and these bushings will outlast the rubber units many times over.
