For the ultimate MINI Performance enthusiast M7 Speed has bundled two of its industry leading bolt-on MINI Cooper chassis reinforcement components to save you money! In this Stage 1 Bundle we have packaged our top selling Strut Tower Brace Kit with our exclusive Under Strut System 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 and Under Strut System (USS) 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 Speed 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 first 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 compare it to the original sheet metal, you will 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 three 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. There may be fitment issues on some applications with the Milltek and Alta exhaust systems.
