BMW Chassis Reinforcement Kits & Parts

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.

Includes RTAB limiter, rear shock tower reinforcement plates and BMW Strut tower plates. If you already upgraded your suspension but are looking for the finishing touch, this kit is what you need. The BMW front strut mount reinforcement plates reduce the risk of the shock tower mushrooming and cracking. The rear shock mount reinforcement plates reduce the risk of the rear shock mount area tearing and deforming. The Delrin rear trailing arm bushing limiters reduce the movement that the RTAB's can make resulting in a tighter rear suspension and with less moment prolongs the bushing life.

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
