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.

Condor's Rear Trailing Arm Pocket Reinforcement Kit is one of the few kits in which the plate is not cut in the shape of a "C". A lot of companies cut them with an opening in order to have less waste when cutting. Their plates are fully connected all the way around making them stronger. This is a must-have reinforcement. The front mounting point of the rear trailing arm is a known area of failure on track driven E36s. Condor's 2-piece reinforcement plate kit reinforces the stock pocket bungs to prevent failure. Welding is required, includes rosette holes. *Does not fit 318ti.

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.

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. Includes Dinan Exhaust Dinan Intake Dinan Strut Brace Dinan Pedal Covers Dinan Badge Features Smiles per gallon instantly multiplied Guaranteed component compatibility and seamless integration 10% price savings when compared to buying the same components a la carte Maximum gains of +6 HP and +5 lb-ft of torque (Exhaust) Smoother, louder,and sportier sound (Exhaust + X-Pipe) Computer-controlled exhaust valves are retained and limit noise during low-speed driving and open fully during high-load conditions (Exhaust) Deletes resonators between the secondary catalysts and rear muffler for increased volume (X-Pipe) Between 11 and 16.6 pounds lighter than the stock depending on the package(Exhaust + X-Pipe and Strut Brace) Reduced intake restriction for Increased turbo efficiency with greater power potential on modified builds (Intake) More robust and aggressive induction soundtrack (Intake) Improved throttle response (Intake) Increased rigidity for sharper handling and reduced flex (Strut Brace) Elevated and stylish high-performance look to the interior (Pedal Pads) Every Experience Package instantly qualifies for the Fabled Dinan deck lid badge
