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.

If you are concerned about strut tower mushrooming and looking for improved handling, the M7 Strut Tower Brace (STB) is the solution. This is the ONLY strut tower brace on the market that features anti-mushrooming technology.

Repeatedly, we've heard the same complaint: strut towers mushroom after heavy impacts from shocks and low aspect ratio tires. Initially, the shock towers take on a barely visible convex shape, but if compared to the original sheet metal, you'll find the horizontal plane has moved as much as 3/8" upwards, making alignment nearly impossible.

This issue often shows up as a slight pull to the left or right, depending on which strut tower is affected. The M7 Strut Tower Brace's end mounting plates solve this problem by sandwiching the sheet metal and shock top plate, creating a reinforced surface that won't bend, even during hard impacts.

The M7 STB features 1/2" (13mm) thick end plates that add extra strength to the strut towers, preventing mushrooming and potentially costly repairs. The cross brace significantly improves handling by adding torsional stiffness to the front body structure, helping keep your tires planted and pointed in the direction you want to go, especially during hard turns. Machined from billet aluminum and matte black powder coated, the M7 Strut Tower Brace boasts a durable black finish that looks great and won't chip or oxidize.

We have customers who won't drive their new MINI off the lot without one and dealers that sell every new MINI with either the M7 Strut Reinforcement Plates or the M7 Strut Tower Brace.

Concerned about clearance? No worries. The M7 STB profile is designed to clear both stock and aftermarket cold air intakes and ECUs. Its modular design allows easy access to the oil filter or any other accessories that might normally be blocked and require removal of the entire brace.

Installation is a snap (often taking less than 20 minutes)! No need for new nuts—the brace uses the three stock nuts on each side. Installation instructions are available online by clicking the "INSTALLATION" link on this page.

The M7 Strut Reinforcement Plates and the M7 Strut Tower Brace are two separate products that address strut tower mushrooming (you only need one or the other).

If your MINI is mainly a daily driver, the M7 Strut Reinforcement Plates are sufficient. If you have performance driving in mind, the M7 Strut Tower Brace is what you're looking for!

Please note:

  • You cannot buy the SRPs and attach the cross-bar at a later time.
  • The brace does not directly fit on the R50 and R52 Non-"S" Cooper due to limited hood clearance of the non-supercharged cars. It will fit but may push up on the hood slightly, requiring molding or cutting of the hood insulation after installation.
  • Trimming of the underhood insulation material may be required to fully clear this brace. This is a very tight space.

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
