Hidden Beauty

Design Story

Torsional rigidity: the bane of race engineers, enthusiasts, & drivers alike! The OpenSpec™ Collection offers complete compatibility. This means that Formawerx Keypieces can operate a number of different vehicles. As car culturalists, we wanted each reference to celebrate an unmistakable value within automotive design. 

OpenSpec™—PPF megaphones the art-form of spaceframe/ weight-saving structure in cars. Often hidden away, truss structures can be found in Group C monsters to humble canyon-carvers like the Miata. Mazda's powerplant structure aimed to provide less twisting of the chassis, and thus a stiffer, more responsive, & exponentially enjoyable driving experience. Our design displays the symbiotic relationship between chassis and body, working together to save weight, create strength, & provide aerodynamic stability. So next time you see an exposed truss structure in a Lotus or even the McLaren F1, thank the proverbial engineer for the work that's often felt before it's seen.
