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.

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.

Rally Road has created a strut bar for the E36 based on the design of the original BMW LTW / Motorsport Strut Bar. Rally Road has improved on the original design in many aspects. The bar ends are machined from a single billet aluminum block. The finish is bright black anodize. This bar looks great and functions as well as the factory original. They even include a raised area on the bar ends so you can place your ///M decal like the original. *Just like the original Motorsport Bar, does not fit cars with factory ASC+T

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.

This item fits the following BMWs:
2006-2011 E90 BMW 325i 325xi 328i 328xi 330i 330xi - Sedan
2007-2011 E91 BMW 325i 325xi 328i 328xi - Touring Wagon
