M7 Speed Under Body Chassis Reinforcement Kit for 02-06 Mini Cooper S Hatchback 05-08 Mini Cooper S Convertible Gen 1 MINI Cooper

One of the biggest improvements you can make to gain grip is stiffening your chassis. A stiffer chassis makes the suspension, like the springs, shocks and sway bars, do their job and keeps the tires in better contact with the ground.

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. Easy to install.

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 which 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 - the same thing you'll say about the M7 USS.

Important: 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.
