Prevent cracks from forming and avoid costly repairs from common problems. This reinforcement plate kit is also strongly recommended as a preventative maintenance item. Our 14 gauge subframe reinforcements plates are made of steel and designed to reinforce the subframe mounting points on your BMW E46 by thickening the metal and distributing the load over a larger area. However, our BMW E46 subframe reinforcement kit can fix this common problem. The most comprehensive kit to keep your E46 on the road for many years to come.Rear subframe failure is a common problem in the BMW E46, and the M3 model did not get factory sheetmetal rear subframe reinforcement. 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. Cars with upgraded power, even when driven on the street, can also. The front subframe is highly stressed during high-performance track driving, and it will crack quickly on a heavily tracked a E46. The E46 subframe has come to be known as a problem child. Our E46 Front Subframe Reinforcement kit is a must-have solution for E46 3-Series that see use on track, or that have upgraded power over stock.
