Stage 2 Chassis Reinforcement Kit | Gen 2 MINI Cooper

For the ultimate Mini Performance enthusiast M7 Speed has bundled the final two pieces needed to transform your MINI from a go-kart into an F1 turning machine. If you already have the M7 Strut Tower Brace this bundle is for you. Add these industry leading bolt-on MINI Cooper suspension components and WOW! instant grip like you have only imagined in your dreams. In this Stage II Bundle we have packaged our exclusive Under Strut System AND the M7 Rear Chassis Brace for the R56 Mini Cooper.

Compared to buying these kits separately you save additional $$$$

 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 "J" 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!

Under Strut System (PN: 56-5M7201)

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 is 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  (PN: 56-510201)

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.

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 use of the rear seats. Handling without sacrifice of passenger comfort. The M7 Rear Chassis Brace is the perfect addition to a serious street or track MINI.  

Please Note: The RCB only fits the R56 & R56S Hatchback Models
