This carbon fiber strut brace uses a flat-oval design with a hinge-less mounting system that makes this one of the best strut braces on the market (especially at the price!). Cornering forces can put stress on the chassis, especially when used with stickier tires and stiffer suspensions.Strut braces help to reduce chassis flex by tying the two strut towers together. This design is stronger than most strut braces that use a hinge on the end that allows additonal flex. This design has fixed end mounts that the strut bar is bolted to. The slim oval tube is 100% carbon fiber for excellent strength and rigidty. The entire assembly is less than 5lbs and installs in minutes.

Fitment note: the end plates on this brace are closed. Some aftermarket front struts have an extra tall strut pin that will interfere with this brace.

The Carbon Fiber ECS strut tower bar kit offers more than just good looks - it also serves to protect strut towers from "mushrooming" or other deformation caused by rough roads or vehicles with stiff suspension and helps to triangulate the front end, providing more consistent suspension geometry with less chassis flex. Strut tower plates should sit flush against the strut towers. If this is not the case, your strut towers are to some extent deformed. This can be easily remedied in minor cases with a block of wood and a hammer. Carbon fiber is an excellent addition to any vehicle and offers a very unique look that is found on some of the most exotic vehicles on the road today. This strut bar kit features a clean woven design that is sure to look phenomenal for years to come and will compliment absolutely any engine bay. Don't settle for a boring stainless steel or aluminum strut bar, your BMW deserves the best. Features high gloss carbon fiber bar and black CNC machines tower plates with stainless steel hardware. Not for SULEV M56 engine models.

Reinforces the strut towers against deformation while adding valuable triangulation to the front end for sharper, more predictable handling. Designed to prevent “mushrooming” and other distortion caused by rough roads or stiff suspension setups, these plates help maintain consistent suspension geometry by reducing unwanted chassis flex. The result? A more stable, confidence-inspiring front end under load. Strut tower plates are engineered to sit perfectly flush against the towers. If they don’t, it’s a sign the towers have experienced some deformation. In minor cases, this can often be corrected using a block of wood and a hammer to carefully restore the mounting surface.
