    For the ultimate MINI Performance enthusiast M7 Speed has bundled 3 of the industry leading bolt-on MINI Cooper chassis reinforcement kits into one money saving package.  In this Stage 3 Bundle we have packaged our top selling Strut Tower Brace Kit, our exclusive Under Strut System AND the M7 Rear Chassis Brace for the R53 MINI Cooper.

    One of the biggest improvements you can make to gain grip is stiffening your chassis. A stiffer chassis allows the suspension, like the springs, shocks and sway bars to work more effectively and do their job as intended; keeping the tires in better contact with the road. The M7 Strut Tower Brace Kit, Under Strut System (USS) an Rear Chassis Brace feature easy to install integrated billet and extruded aluminum pieces that will brace, connect, and triangulate your Mini Cooper chassis for greatly improved chassis stiffness. Make maximum grip, increase steering response and reduce understeer during aggressive turn-in or emergency maneuvers.  This is a "WOW! Why didn't I do this sooner?" addition to your favorite speed monster.  Buy the best, buy the original…you will not be disappointed! Easy to install. M7 Tuning products are Engineered, Tested & Proven to PERFORM!

    Strut Tower Brace Kit

    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 which we were the fist in the industry to develop!.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 would 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 matt 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 3 stock nuts on each side. Installation instructions available on line by simply clicking the "INSTALLATION" link on this page.

    Important Info for Customers: The M7 Strut Re-Inforcement 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!

    Note: The brace does not fit on the R50 Cooper due to limited hood clearance of the R50. M7 suggests the SRP Plates for this application.

    Under Strut System

    Not many upgrades will force you to say, "damn that's incredible" or just plain "wow." The M7 Under Strut System (USS) features three integrated pieces that will brace, connect, and triangulate the bottom of the chassis for greatly improved chassis stiffness. This improved stiffness will give the MINI better turn-in capability allowing the car to rotate into the corners with ease, and also greatly reduce understeer.The M7 Under Strut System is made of extruded and CNC machined aluminum that comes in a black anodized finish that iss durable and designed to prevent chipping and corrosion. Stainless steel fasteners and necessary tools for nut insert installation are all included! We'd say our months of rigorous testing at local race tracks, treacherous canyon roads and sweeping on/ off-ramps, were a good investment just the same thing you'll think about the M7 USS.

    Installation Notes: If you are not using a lift, please be sure that you have enough room so you can drill square (perpendicular)to the underbody. We cannot stress enough how important this is. Drilling at an angle will cause the hole for the nut insert to be too large for proper installation. Please do NOT attempt to install your USS on a slanted driveway. Note: There may be fitment issues on some applications with the Milltek and Alta exhaust systems. 

    Rear Chassis Brace

    During hard cornering, the MINI is prone to chassis flex that results in poor handling characteristics and the need for the driver to compensate. M7 now offers a way to fix this problem with the M7 Rear Chassis Brace (RCB), one of the additions to the M7 Suspension Solutions line. This modification is perfect for people who want ultimate chassis stiffnes but with adding an intrusive rool bar or roll cage.

    Our first installed system impressed the customer so much that he was inspired to call back within 20 minutes of leaving our office with reports of how the brace instantly changed his car's traits. He described how the rear end of the car felt heavier and more planted to the ground, and any kind of fishtailing effect felt done away with. Overall the handling of the car felt tighter and more responsive to the driver's commands.

    The M7 Rear Chassis Brace is a great compliment to the immensely popular M7 Under Strut System (USS). Using the two together will give you the best in chassis stiffening without going the route of a roll cage.

    Besides the benefit of more predictable handling, the Rear Chassis Brace allows for comfortable use of the rear seats. Unlike a roll cage, there are no harness bars or cross members to remove to allow access to the rear seats. The position of the rear seats is also unaffected!

    Going a step further, with some minor modifications you can mount a fire extinguisher or other accessory equipment (not included) to the RCB. As many weekend track warriors find out, a fire extinguisher is often required by driving event coordinators. By attaching the fire extinguisher to the RCB, you can meet the organization's requirements and have safe and easy access to the fire extinguisher if the need for it arises. This eliminates the need to drill into the floor of the car or worry about not having a roll cage to mount the fire extinguisher. Since fire extinguishers mounted to the RCB are in the boot of the MINI, all passenger space is STILL unaffected by installation and use of the RCB.

    Handling without sacrifice of passenger comfort, and a place to mount a fire extinguisher: the M7 Rear Chassis Brace is the perfect addition to the street MINI that sees the track as well.

    Optional RCB Accessory Plates. Easily place and remove these lightweight plates that can hold anything you want to mount on them. Data acquisition systems, First aid kits, emergency supplies...anything! A great addition for mounting all youR cool stuff without drilling into floors and interior panels. Easy in and out for quick track-to-street and street-to-track conversion

    Please Note: The RCB currently fits only the coupe.
