Upgrade your handling and rigidity performance with a track proven brand. Introducing our Turner Carbon Fiber Strut Brace for G80/G82 M3/M4 owners!  Our unique strut tower brace offers more than just good looks - it reduces chassis flex to stiffen the suspension, and helps triangulate the front end, providing more consistent suspension geometry. 

Designed and tested in-house, we are proud to offer a precision engineered structural component that ensures power is transferred properly and not lost through chassis flex, without any increase in NVH. Our Carbon Fiber Strut Brace is lightweight (3.31 lbs. vs 7.71lbs. OEM), extremely rigid, and comprised of carbon fiber and aluminum chassis mounts with an oval cross-sectional area for increased rigidity over the factory steel braces. Not only will it enhance your driving experience but also provide an eye-catching addition to your engine bay. 

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. This kit includes everything you need for installation.
