This system, with it's 3 integrated pieces, 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, also greatly reducing under steer. The M7 Under Strut System is made of extruded and CNC machined aluminum that comes in a black anodized finish, greatly reducing the chances of chipping and corrosion. Stainless steel fasteners and necessary tools for nut insert installation are all included!
