Genuine BMW BMW Chassis Reinforcement Kits & Parts for BMW Z3 (1996-2002)

Clear BMW chassis

Made in the USA

As 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.

The shock towers on the E36 and Z3 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. BMW part number 31312489795

Original BMW chassis reinforcement developed for the special M3 LTW (Lightweight) model. This tubular-steel part connects the front subframe to the body and gives the car a more solid feel with less flex. Every convertible and Roadster model uses a similar design to address inherent chassis flex in the front of the car. Fits all E36 and Z3 chassis BMWs.

By adding this Genuine BMW Motorsport cross brace, you'll dramatically reduce that flex and movement in the front half of the body on your E36. This is a must-have on any BMW E36 that has an upgraded suspension, larger sway bars, is driven aggressively or sees ANY amount of track time. The Xbrace is a factory BMW Motorsport part, so design and fit are both great and the installation is straight forward and easy. Perhaps best of all is the low price compared to the impact the Motorsport X-brace has on the E36 chassis. Does not come with any needed hardware for installation.
