Subframe Bushing Reinforcement Combo Kit - BMW E46


This combo kit comes with Revshift BMW E46 subframe bushings in the hardness of your choice and the subframe weld in reinforcement kit.

The weld in rear subframe / chassis reinforcement kit fits all BMW E46 models.

The rear subframe mounting points on the E46 are notorious for cracking and ripping out over time. This kit welds onto the chassis preventing cracks and inevitable expensive damage to your vehicle. All reinforcement plates are precision laser cut from 14 gauge steel.

Revshift polyurethane rear subframe bushings completely replace the oem rubber bushings on the E46 (323, 325, 328, 330, M3, Z4). These bushings stiffen the subframe mounting points improving the vehicles handling capabilities.

  • Improves handing
  • Will not wear out like oem bushings
  • Properly dampens the rear subframe
  • Revshift bushing lube included
  • Lifetime warranty

Formula Drift Spec Subframe to chassis clearance is specified for the E46 in the Formula D rule book. We designed these bushings to comply with the FD specs. They will pass tech in all FD sanctioned drift series.

1x left rear chassis reinforcement
