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.

If you drive your BMW in a spirited manner, have an extensive list of modifications such as turbo/supercharger or track your BMW, reinforcement of the subframe is a must. E36 BMWs are known for being very capable machines, but they are also known for less than stellar subframe rigidity. With this kit, it will reinforce where the subframe meets the chassis, making for a much stronger and much more rigid frame. You will notice sharper and more precise handling, and you can stop worrying about costly chassis/subframe damage.

Welding is required, professional installation is recommended.

These are the BMW factory chassis reinforcement plates that came on the E36 M3s (some very early 1994-production M3 models may not have had them). This reinforcement should be done on all non-M E36 models especially when used in track/autocross situations. The kit is a set of 4 plates that are added to reinforce the rear subframe chassis mounts. BMW discovered that over time, due to the bending of the rear of the chassis in conjunction with the movement allowed by the rubber bushings in the rear, the chassis mounting points for the subframe would flex, weaken, and if left unattended, rip out of the chassis. The stock mounts are basically a flat plate with an internally threaded tube that are welded to the chassis. The flex of the rear subframe causes the threaded tube and mounting bolt to act as a lever arm at the point where the flat plate is welded to the chassis, weakening the surrounding sheet metal. Due to the direction of force of the torque applied by the drivetrain on the subframe, the first mount to rip out is the passenger�s side front mount, followed by the drivers side rear mount. Having these plates welded to the underside of the chassis significantly stiffens the mounts and stops the weakening of them.

In order to weld these plates in, the rear suspension, rear subframe, exhaust, and driveshaft must be removed. It is also strongly recommended that the back seat, rear interior, trunk interior, and fuel tank are removed and all fuel lines are capped to reduce the fire hazard while welding.

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.

Going beyond its Foundation counterpart, the Dinan Experience packages address not only the engine but also the chassis for a complete solution in the form of a wholly tuned Dinan vehicle. While adding power modifiers is often the go-to path when beginning the modification journey, it does not fully consider what makes the car infinitely more enjoyable in scenarios outside of WOT pulls. With the addition of suspension upgrades integrated alongside the power adders, the vehicle is transformed into something more than just the sum of its parts. It's a comprehensive answer to delivering additional technical capabilities in the form of increased engine performance and better handling along with improvements to aesthetics (looks and sound) in a package designed with reliability and safety in mind. This union of power and handling modifications results in a true OEM+ experience - the Dinan Experience.
