BMW Chassis Reinforcement Kits & Parts for BMW 3 Series E36 (1992-1998)

Clear BMW chassis

Please ensure your correct model is selected

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.

Rally Road Productions, Inc. is a team supported by a group of people with great abilities in their area of expertise. From the "web guy" and driving instructor friends, to owners of various machine shops, they have surrounded ourselves with people that can be trusted to create and manufacture quality products. This is the key to ensuring everything that they sell will perform as it was intended. The goal is to increase customer satisfaction and make the customization or performance enhancement of your vehicle a more enjoyable venture.

Have you ever snapped a transmission brace under full throttle? NOT a fun experience. For that reason, Rally Road has come up with the very last transmission brace your E36 will ever need. 

Back when the minds at BMW set out to design the E36's lower transmission support, they executed perfectly. A cast piece manufactured from lightweight aluminum would surely provide the proper support for the business end of the powertrain. This part functioned fine...mostly...when the vehicle was driven modestly. However, push it too hard and this brace becomes perfectly unusable when it snaps in half. 

This upgraded piece is manufactured out of solid steel. Laser cut, precision CNC bent, and then tig welded together - this thing is ready to take a beating. Finish it off with a flawless black powder coat and what you have is a transmission brace that is as beautiful as it is bulletproof. Whether you're considering this as an alternative to an already broken piece or just shopping for your next mod, this is a must-have for ANY E36 owner.

This is a direct replacement for the factory BMW rear shock mount reinforcement, as equipped by BMW on Z3 models. This also fits all E36 and E46 models as well. Turner Motorsport makes our own that are thicker but these can also do a good job of preventing cracks and deformation of the rear shock towers. Priced per reinforcement plate. Order 2 to cover both rear shock towers. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future.
