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

As Used on Project E36 M3
Original BMW chassis reinforcement developed for the special M3 LTW (Lightweight) model. This tubular-steel part connects the front subframe to the body and gives the car a more solid feel with less flex. Every convertible and Roadster model uses a similar design to address inherent chassis flex in the front of the car. Fits all E36 and Z3 chassis BMWs. 

By adding this Genuine BMW Motorsport cross brace, you'll dramatically reduce that flex and movement in the front half of the body on your E36. This is a must-have on any BMW E36 that has an upgraded suspension, larger sway bars, is driven aggressively or sees ANY amount of track time. The Xbrace is a factory BMW Motorsport part, so design and fit are both great and the installation is straight forward and easy. Perhaps best of all is the low price compared to the impact the Motorsport X-brace has on the E36 chassis. If your car is a 1992-1996 model, be sure to select the option below so we include the proper hardware (nutserts) to use during installation (1997-1999 cars don't require them.) 

The E36 Motorsport X Brace / Cross Brace fits:
1992-1995  E36   325i, 325is, 325ic
1996-1998  E36   328i, 328is, 328ic
1997-1999  E36   323is, 323ic
1992-1999  E36   318i, 318is, 318ic, 318ti
1995-1995  E36 M3   3.0 liter
1996-1999  E36 M3   3.2 liter
