SuperPro SPF3946K Rear Subframe Mount Bushing Set – 2011 BMW 1 Series M (E82/E88)

Upgrade rear-end stability and chassis control with the SuperPro SPF3946K Rear Subframe Mount Bushing Set, engineered specifically for the 2011 BMW 1 Series M. This high-performance polyurethane bushing kit replaces compliant factory rubber mounts to help reduce rear subframe movement, sharpen handling response, and improve power delivery—ideal for spirited street driving, track days, and performance builds.

Key Benefits

  • Reduced rear subframe deflection: Helps minimize unwanted movement for improved stability and traction.
  • Sharper handling & turn-in: Increases chassis precision and rear-end confidence during aggressive cornering.
  • Durable polyurethane construction: Designed to resist oil, heat, and wear versus standard rubber mounts.
  • Direct-fit replacement: Fits factory subframe locations—no cutting or fabrication required.
  • Long service life: Maintains performance over time with reduced deformation compared to rubber.

Why Upgrade Rear Subframe Bushings on the 1 Series M?

The BMW 1 Series M benefits significantly from increased rear subframe control. Worn or soft factory mounts can contribute to rear-end “slop,” inconsistent traction, and delayed chassis response. By tightening the subframe interface, this kit supports better feedback, stability under load, and improved driveline response especially on lowered or track-driven setups.
