Overview

The Turner Motorsport Rear Subframe Chassis Reinforcement Kit is designed to address common failures in the E46 chassis. This kit reinforces the chassis sheet metal at the subframe mounting points by thickening the metal and distributing the load over a larger area. It can be used to repair existing chassis damage or as a preventative maintenance measure.
Show original supplier description
The Turner Motorsports Rear Subframe/Chassis Reinforcement Kit (TMS-TDR4675412) is engineered to address a known issue in the E46 chassis where the rear subframe mounting points can fatigue and pull away from the sheet metal. This problem arises from the torsional load transmitted from the differential through the subframe into the chassis. BMW's attempt to mitigate this with a front subframe cross-member inadvertently concentrates the load on the rear mounting points, leading to failures even on low-mileage vehicles. This reinforcement kit works by thickening the chassis sheet metal at these critical subframe mounting points and distributing the load over a significantly larger area. Updated in 2020, the kit offers increased surface area for maximum reinforcement. This kit is compatible with a wide range of E46 BMW models, including the 323i, 323ci, 325i, 325ci, 325xi, 328i, 328ci, 330i, 330ci, 330xi, and M3, covering model years from 1999 to 2005. Installation instructions are available, and the product is backed by Turner Motorsport's Lifetime Replacement Program.
