The Alpha N Carbon roof for BMW E82 1M is made entirely of carbon fiber, so it can save about 5 kg compared to the original roof. Due to the weight reduction at the highest point of the car, the center of gravity of the vehicle shifts downwards, which is of particular interest for tracktools.
The roof can be ordered with or without clear lacquer. A clear lacquering is recommended for immediate use. If, however, the roof is to be painted in the desired color, the clear lacquer on the carbon is unnecessary and can be saved.
