BMW Strut Braces & Stress Bars

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 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.

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 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.
