Even a stock MINI is fairly low to the ground, and when you install lowered springs or low profile tires you should absolutely protect the bottom of your drive train.
The factory installs a short plastic deflector, but a serious driver should consider the Steel Skid Plate as a replacement. It attaches in the stock location but also extends further back to protect the very vulnerable power steering cooling fan which is exposed under the car. While this fan is protected by a fuse (which will blow if a plastic bag becomes caught in the fan), this skid plate will prevent the resulting loss of power steering.
This Skid Plate weighs 22.5lbs, made from Steel with a powder coated finish.
