What material is the geniune MazdaSpeed kit made out of? Is it the same material as the OEM front bumper or something else?

RXE16T

Same as OEM.
Urethane I think?

The OEM front bumper is made for a material called TPO. It is a flexable material made of Polypropylene and rubber. The parts are made by injection molding. Better for higher volumes. The Mazdaspeed front bumper is made from a urethane. These parts are made by a process called RIM or re-action injection molding. In this case two materials are injected into a mold and harden when mixed. Better for low volume.
