Rear subframe cracking is a well-documented issue on the E46 chassis. As mileage, grip, and suspension loads increase, stress concentrates at the rear subframe mounting points where the factory sheet metal can fatigue, crack, or tear from the chassis.

Our Rear Subframe / Chassis Reinforcement Plates are designed to address this problem by reinforcing the mounting areas and distributing loads into a larger section of the chassis. Rather than masking damage, these plates add structure where the E46 needs it most—whether as a preventative upgrade or as part of a proper repair.

Precision cut from .125" (1/8") steel, the plates are intended to be welded in and fully integrated into the chassis. They’re best installed during subframe service or repair, and are well-suited for cars that see spirited street driving, sticky tires, and track use.

Features:

  • Reinforces factory rear subframe/chassis mounting points
  • Helps prevent cracking and long-term fatigue
  • Distributes subframe loads into stronger chassis areas
  • Precision cut from .125" (1/8") steel
  • Designed for weld-in installation

Installation:

  • Welding required
  • Professional installation recommended

Fitment: BMW E46




Increased Strength, Safety, & Reliability with E46 Rear Subframe Reinforcements

Increased Strength, Safety, & Reliability with E46 Rear Subframe Reinforcements

Our E46 subframe reinforcements enhance your chassis' overall strength and safety. How do they do this? By reinforcing the subframe mounting points, you significantly reduce the flex in these critical areas, which can lead to cracks and long-term damage. Our chassis reinforcement kit adds a layer of protection to your BMW E46, ensuring that the chassis can handle all the stress track days throw its way.

With our reinforcement plates installed, drivers can rely on the additional strength and increased reliability, that our reinforcements provide. The subframe reinforcements distribute the load across a broader surface area, minimizing the risk of failure and costly repairs. Whether you're repairing a failed rear subframe mounting point or proactively preventing future issues, our kit provides the reliability and durability you need both on the road and the track.

How to Install Our E46 Subframe Reinforcements

Installing our E46 subframe reinforcement kit requires welding, so we recommend professional installation to ensure the best results. Here's a step-by-step guide if you are looking to install it yourself:

  1. Remove the Rear Subframe: Begin by carefully removing the rear subframe from the car. This allows easy access to the mounting points and ensures proper installation.
  2. Clean the Area & Mark: Use a grinder, wire brush, and degreaser to clean the chassis thoroughly. Once clean, position the reinforcement plates on the chassis using the provided bolts and mark their locations.
  3. Prepare for Welding: Ensure that all original paint or undercoating has been removed from the areas that will be welded. This step is crucial for achieving strong, durable welds.
  4. Weld in Place: Start by tack welding the plates in place. Then, proceed to fully weld along all edges of the plates, taking care not to build up too much heat in one area to avoid warping.
  5. Inspect Welds: After welding, inspect all welds to ensure they are solid and free from defects. Sand down any rough edges to prepare for reassembly.

By following these steps, you can reinforce the subframe mounting points so that your E46 is ready to handle the demands of on-track driving.
