Genuine BMW BMW Chassis Reinforcement Kits & Parts

Made in the USAAs much of an "Ultimate Driving Machine" it is, many BMW models unfortunately suffer from weak points in the chassis. Over the years we have uncovered many weak or failure-prone areas in the chassis and have developed our own reinforcing solutions for them. And we continue to be the leading experts on BMW chassis reinforcing. Failures can come from a number, or combination, of causes: improper maintenance, age and mileage, poor design, environmental factors, poor repair work, and over-stressing modifications. The longer you let your car go without repairing or reinforcing these areas, the closer it gets to crumbling apart. Our chassis reinforcement kits are designed to first identify potential weak points and then strengthen and reinforce the existing design.

Most of our kits are not labor intensive although welding is usually required. If you suspect your chassis may have structural problems we recommend taking it to a well-known bodyshop or restoration shop. (find out who your local BMW dealer uses - we sell many of our kits to dealer-authorized repair shops). Making the preventative fix simple and effective is better than a long and complicated repair after the failure. Our kits are not usually used for fixing existing damage (only your body shop can determine the correct course of action). But our kits have been proven under extreme conditions on racetracks around the world to prevent many of the costly - and dangerous - chassis problems.

Like the E36 before it, the front strut towers on the E46 are notoriously weak. Under normal driving conditions with a stock, fresh suspension it is unlikely that you will ever have a problem. But with an upgraded street or race suspension with firm springs much of the energy from pounding the road is transmitted to the thin sheet metal in the strut tower. This pounding will cause the tower to deform or even crack. Look for 'mushrooming' or deformity around the holes for the three mounting studs at the top of the strut tower. The sheetmetal around the holes should really be flat and square. Poor shocks or stiff suspensions will actually cause this sheetmetal to pop up.

These factory BMW reinforcement plates will help disperse the energy and save you from costly repairs in the future. A strut brace also helps to prevent this but these plates are designed to reinforce the strut tower from the bottom. The install over your strut mount or camber plate and simply add thickness (strength) to the strut tower. They can be sandwiched in place and do not require welding.

2001-2006 E46 BMW M3*
* - The stock M3 upper strut mount already does a good job of dispersing the loads of the suspension. These reinforcement plates will fit a stock mount for added strength but need to be trimmed to fit inside the strut tower. The are very strongly recommended for all M3s with coil over suspensions because aftermarket coil overs typically have a smaller surface area for their strut mounts.
