BMW Chassis Reinforcement Kits & Parts for BMW G42 M240i xDrive B58 3.0L

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.

Carbon Performance Intake and 3-Point Strut Brace Kit

We know the G20 and G42 BMW models deliver an incredible driving experience, whether equipped with the B48 or B58 engine. However, we’ve identified key areas where performance and style can be taken to the next level. That’s why we’ve developed the Turner Carbon Fiber Performance Kit, combining our Turner Carbon Fiber Intake System and Turner Carbon Fiber Strut Tower Brace into one ultimate package.

Turner Carbon Fiber Intake System

Upgrade your engine bay with our Turner Carbon Fiber Intake System, designed for maximum performance and style.

Unmatched Airflow: Our intake flows 8% more air than the factory system (445.0 CFM vs. 410.1 CFM), reducing stress on your turbo and delivering optimal performance.
Lower Intake Temps: The enclosed carbon fiber lid reduces intake temperatures by up to 13°F compared to open intakes, ensuring consistent performance.
Premium Materials: Built with a gloss carbon fiber intake tube featuring MAF scaling, a durable 6061-T6 anodized flange, and a wrinkle black powder-coated heat shield for strength and style.
High-Performance Filtration: Includes a conical, reusable air filter with 8-ply oiled cotton gauze and a velocity stack for superior filtration and efficiency.
This intake is the perfect blend of form and function, offering noticeable performance gains while giving your engine bay the high-end look it deserves.

Turner Carbon Fiber Strut Tower Brace

Inspired by the performance-focused "M" chassis, our Turner Carbon Fiber Strut Tower Brace is engineered to improve handling and chassis rigidity.

Enhanced Handling Dynamics: Reduces chassis flex by effectively distributing cornering loads between the strut towers, maintaining consistent wheel alignment geometry during aggressive driving.
Precision Engineering: CAD-designed for a seamless fit with factory mounting points, our strut brace is built with lightweight yet ultra-rigid carbon fiber featuring a 2x2 twill weave.
Durable Construction: Features billet aluminum mounts machined from 6061-T6 aluminum, type II anodized, and securely bonded to the carbon fiber for uncompromised strength and stability.
Striking Aesthetics: Our high-gloss carbon fiber design adds a motorsport-inspired look to your engine bay, complementing any BMW enthusiast's style.
Why Choose the Turner Performance Kit?

Performance Gains: Maximize airflow and structural rigidity to make your G20 or G42 sharper, more responsive, and more enjoyable to drive.
Premium Appearance: Transform your engine bay with matching carbon fiber components that deliver both performance and head-turning style.
Easy Installation: Both the intake and strut brace are designed for a straightforward, bolt-on installation using factory mounting points—no modifications required.
Whether you’re hitting the track or carving through back roads, the Turner Motorsport G20/G42 Carbon Fiber Performance Kit ensures your BMW delivers on all fronts: performance, handling, and aesthetics. Upgrade your 2 or 3 Series today with the Turner kit designed to bring your driving experience closer to the ultimate M-car level.
