Reinforcement plates behind the subframe for the BMW E46. The most comprehensive kit to keep your E46 on the road for many years to come.BMW 3 Series E46 Subframe Reinforcement Plates (Street Version – Steel) Turner's subframe reinforcement kit paired with structural foam to assist in load dispersal and prevent new cracks from forming by limiting sub frame mount movement. With this comprehensive kit, you get the best of both worlds. This is accomplished by installing reinforcement plates at the subframe mounting points, which thicken the metal and distribute the load over a larger area.ĮCS Tuning has come up with what we believe to be the best possible solution. Turner Motorsport has also developed a solution to address subframe issues. Though structural foam helps, it does not completely address the issue. Option 2: Turner Motorsport Reinforcement Kit. The key component missed is the failure of the spot welds in the sheet metal. Though this addresses the failures in the subframe, it is not a complete fix. Their solution was structural foam to fill the void between the underside of the chassis and the top of the trunk. BMW realized this issue shortly after the release of the E46. There are two common fixes for this issue. However, this also causes the load to be transmitted to the left rear of the subframe, which has become a common failure point. The result is reduced twisting action on the sheet metal.
When BMW designed the rear suspension they placed a cross member on the front two mounting points of the subframe, which keeps the front mounting points from having problems by placing the bushing and the stud in double-sheer. As with any problem, the important part becomes finding the cause. With failures showing in all mileage ranges of cars, ECS and Turner come together to give you the most comprehensive fix available. The E46 subframe has come to be known as a problem child.
