BMW Strut Braces & Stress Bars for BMW G42 M240i xDrive B58 3.0L

Clear BMW chassis

Please ensure your correct model is selected

BMWs need some added chassis strengthening in the front. You may notice some "chassis flex" when cornering or driving over a bumpy road. The reason for this is the incredible amount of force being applied to front strut towers. They have a tendency to flex when force is applied to them. Tying the strut towers together with a brace reduces the amount of flex and soldifies your car's chassis. Easy installation.

The Dinan G2x Strut Tower Braces provide additional rigidity and sharper handling to the chassis by reducing flex under hard cornering conditions. With more control, spirited driving becomes easier and infinitely more enjoyable. Not only do the braces provide a performance benefit but they replace arguably the biggest eyesore in the factory engine compartment. Transforming the blight that is the factory smashed aluminum tubes into a notable highlight that augments the engine bay rather than detract from it. The attractive black anodized billet aluminum braces can be installed in a matter of minutes and used in conjunction with either the stock or Dinan intake systems with the brace valley (D760-0058 / D760-0059). Features: Improved chassis rigidity. Decreased flex during cornering. Solid black anodized billet aluminum for maximum strength and visual appeal. Compatible with stock and Dinan Intake Systems with brace valley (D760-0058 / D760-0059) Bolt-on installation.

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.

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.

G20/G42 Carbon Fiber Strut Brace

For G20 and G42 BMW models equipped with the B48 or B58 engines, the driving thrill is undeniable. Yet, these cars lack a crucial component found in high-performance M models: structural chassis bracing. With Turner Motorsport’s 3-point Carbon Fiber Strut Brace, you’re adding the missing link to your BMW, mirroring the handling stability of an M3 or M4. This is the only strut brace that elevates G20/G42 handling by emulating the stiffness of an M-series chassis, giving you a dynamic edge on both road and track.

The strut brace fits seamlessly into your BMW using the original factory hardware and an included stud kit, offering a hassle-free, direct installation with no modifications required. Designed and tested in-house by Turner Motorsport, this brace reduces chassis flex, enhancing control during spirited driving and providing a tighter, more responsive feel. Constructed from high-strength carbon fiber with billet aluminum end brackets, this strut brace boosts performance while adding an eye-catching focal point to your engine bay.

Strut Brace Features:

Enhanced Chassis Rigidity: Reduces flex by linking the strut towers, promoting a more precise steering response. Street and Track Ready: Engineered for the best of both worlds, offering stability in all driving conditions. Premium Carbon Fiber & Billet Aluminum: Lightweight yet highly rigid, with a stunning woven 2x2 twill finish. Easy Installation: Fits perfectly with stock mounting points using supplied hardware, ensuring a hassle-free setup. Carbon Fiber: Performance & Style

Turner’s strut brace uses structural carbon fiber, designed to endure the rigors of aggressive driving without compromising aesthetics. The brace's distinct, gloss-finished carbon fiber weave adds a sophisticated, high-performance look akin to exotic supercars. Engineered for precision, this brace effectively distributes cornering forces between the strut towers, minimizing chassis distortion and maintaining optimal wheel alignment, even in hard turns.

Turner Motorsport G-Chassis Carbon Fiber Engine Cover for B58 Engines

Give your G-Chassis BMW’s engine bay a polished, refined look with Turner’s Carbon Fiber Engine Cover. This direct replacement cover is crafted from hand-laid, gloss-finished carbon fiber, delivering a resilient, UV-protected finish. With an OE-style indentation for the BMW badge, this cover complements your engine bay with a sleek, factory look that stands out.

Engine Cover Highlights:

Direct Fitment: Seamlessly replaces the stock cover, utilizing factory mounting grommets and hardware. Durable Gloss Finish: Ensures long-lasting shine and UV protection. Distinctive Style: A premium upgrade that elevates the aesthetic of your B58 engine. Installation Notes:

Simply transfer the OE grommets and badge from the stock cover to the carbon fiber engine cover for a perfect fit—installation takes seconds!
