BMW Chassis Reinforcement Kits & Parts for BMW G42 230i B46 2.0L

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.

Reduces chassis flex for improved handling and control. Beautiful carbon weave for both a functional and aesthetic enhancing upgrade for your G20 or G42!

The G20 and G42 come in a variety of different models offering a variety of performance options. Whether you have a B48 or B58 they both provide an exhilarating driving experience but are missing a key component found on the M3 and M4, chassis bracing. Taking performance cues from the more performance based "M" chassis we are able to bring an immense value add to your new 2 or 3 series to get the most out of your driving experience with our new 3-point strut brace. This is the only strut brace on the market that takes the handling characteristics from the M3 and puts them to use on your vehicle.

An instant upgrade with no modification needed. Fits directly on your vehicle utilizing factory hardware and supplied stud kit. Designed for both street and track use this 2 piece strut brace is mounted together to create one uniform brace for the best improvement in handling.

Strut tower braces are an excellent and common handling upgrade that work by bracing the shock towers together to reduce chassis flex during cornering. Our engineers designed and tested our one of a kind carbon fiber strut brace in-house to increase chassis rigidity and improve handling during aggressive driving in your 2 or 3 series G chassis BMW. Turner Motorsport has engineered a lightweight* and extremely rigid strut brace kit comprised of carbon fiber with billet aluminum end brackets that will not only enhance your driving experience but also provide an eye-catching addition to your engine bay. This addition gets your chassis once step closer to competing with the BMW M cars that come equipped with factory strut braces!

Our Turner Carbon Fiber Strut Tower Brace for your G20/G42 is incredible! Not just a show piece, This front strut brace is a precision engineered structural component that ensures power is transferred properly and not lost through chassis flex, without any increase in NVH. Adding the strut tower brace allows cornering load to be distributed more competently between both strut towers to reduce chassis flex, preventing changes in wheel alignment geometry that can negatively impact handling.

Carbon fiber is an excellent addition on any vehicle, and offers a very unique look that is found on some of the most exotic vehicles on the road today. This strut brace kit features a clean woven design that is sure to look phenomenal for years to come, and will absolutely compliment your engine bay.
