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

    Over and over we've heard the same complaint: the strut towers mushroom after heavy impacts from the shocks and low aspect ratio tires. At first glance the shock towers take on a barely visible convex shape, but if you compare it to the original sheet metal, you would find the horizontal plane has been moved as much as 3/8" upwards, throwing the suspension out of any possible alignment fix.

    The problem will most likely show up as a slight pull either left or right depending on which strut tower is buckled. The end mounting plates of the M7 Strut Tower Brace will solve this problem by sandwiching the sheet metal and shock top plate, creating a reinforced surface that will not bend, even during hard impacts.

    The M7 STB features 1/2" (13mm) thick end plates that add extra strength to the strut towers and prevent mushrooming and potentially costly repairs. The cross brace greatly improves handling by adding torsional stiffness to the front body structure. This helps keep your tire planted on the ground 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 features a durable black finish that looks great and will not chip or oxidize.

    We have customers that 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 M7 Strut Tower Brace.

    Concerned about clearance? No worries. The M7 STB profile is designed to clear both stock and aftermarket cold air intakes & ECUs. The strut tower brace's 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 available online by simply clicking the "INSTALLATION" link on this page.

    The M7 Strut Reinforcement Plates and the M7 Strut Tower Brace are two separate products that have the same function in regards to strut tower mushrooming (you only need one or the other).

    • If your MINI is mainly a daily driver, the M7 Strut Re-Inforcement Plates are sufficient for your needs. 
    • 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 fit on the R50 and  R52 Non-"S" Cooper due to limited hood clearance of the non supercharged cars. M7 suggests the SRP (Strut Reinforcement Plates) for this application.
    • Trimming of the underhood insulation material may be required to 100% clear this brace. This is a very tight space.

    M7's instructions were clear. The product is very well made. The holes for the anti-mushroom plates aligned perfectly. Once assembled the brace is very stiff and looks great! Review by Grand-Cayman (Posted on 6/10/2019)

    10 Min Install....Instant Benefit
    Would Recommend when you put mods on your wife's car, especially those that are not as obvious, and she texts you 20 min later saying "WOW that made a huge difference to the feel of how the car gets through the turns" you know you've done well.

    As easy an install as you'll find so long as you don't have to work out a little mushrooming as I had to.

    Craftsmanship of the part was great and not to mention that black mat finish just looks cool.

    A bit on the pricy side for a sway bar but should be worth it in the long run...would recommend it for sure.

    Installed yesterday, so far so good
    Would Recommend
    Corrected the problem and the car drives great. Great quality and installed easily. Long term, we'll wait and see! Review by Joe (Posted on 5/6/2017)
    Solid & Sharp
    Would Recommend
    Great looking product and just a note that the hood will be pushed up at the rear a bit until the padding under the hood forms to the bar. You could wet it with water if it bothers you that much in order to speed up the process of shrinking. You feel the difference more if you accelerate thru the gears as if your doing the 1/4 mile. The front wheels feel and stay planted. Review by George (Posted on 1/8/2017)
