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.

Karbonius Composites has taken inspiration from BMW's performance strut bar to create their own strut bar. The result is an extremely strong but light brace, which adds not only strength and stability, but also a spectacular eye-catching look. Strut tower braces are very common and effective upgrades for a vehicle that allow for improved structural strength while preventing tower flex and alignment changes during spirited driving. This brace is constructed with carbon fiber and comes with a matte finish, natural aluminum color for the tower mounts, and a clear varnish with no logos underlaid. Includes titanium nuts for mounting. No other modifications needed to install. Estimated shipping time from order 3-5 weeks. Features: Perfect fitment and easy installation. 100% carbon fiber Exclusive and numbered piece 6 titanium nuts included. 2-year warranty

BMW's G80 and G82 M cars are arguably two of the best-built BMW chassis to date, but it does have a few shortcomings. One of the first design weaknesses many people notice right away are the ugly, simplistic front strut brace bars. With the level of detail put into the rest of the M3 and M4, these plain steel bars seem like an afterthought. Vargas Turbo Technologies felt there was major room for improvement and set out to design a new brace kit that is aesthetically pleasing while retaining the strength and fitment of the OE bars. The result is a beautiful, functional 3 piece design with an interlinking "V" bar and center support bar. These Strut Braces are CNC machined from 6061-T6 aluminum and are anodized in Black, Red, or Clear.

While BMW did a beautiful job on the F9X X3/4M’s they sure decided to get cheap out on the strut bars. Ugly steel bars with no real pop or aesthetically pleasing qualities seem like an afterthought to such a well-thought-out car. Well, here at VTT we decided to do something about it, and immediately took our bars off, and let our engineers go to work on a solution. What they came up with is beautiful, and functional. 100% CNc machined from 6061-T6 aluminum and anodized in a variety of colors The result adds a gorgeous look to your X3/4M engine bay, and what BMW should have done from the factory.
