This product is manufactured by using high quality Pre-Pregged (Dry) Carbon Fiber. In addition to the standard Pre-Pregged carbon process our product has been designed using 3D scanning data and produced within a CNC aluminium mould. We have also enhanced our laying processes to minimise waviness throughout the product. These manufacturing techniques will ensure our parts will look better, fit better and be much more durable than the competition. For more information about which Carbon suits you click here.
