This bumper set is made from PP plastic. Installation is extremely simple, as all parts required for installation are included in the delivery or can be taken from the original part. The quality and fit are excellent. Our bumpers/spoilers are machine-made from PP plastic using an injection molding process. Original bumpers are also made from PP plastic - this is evidence of the very high quality of the plastic. It is extremely resistant and robust. This is of course a very positive property for a bumper that should not be damaged by every little stress. As all of our bumpers are machine-made, there are no manufacturing tolerances. All bumpers are guaranteed to be the same in terms of shape and fit.
