VALIDATING PERFORMANCE SUSPENSION PARTS ADVANCES

A forum at the 2013 SEMA Show discussed three approaches to ensure performance parts compliance with Federal Motor Vehicle Safety Standard 126. Panelists also explained how simulation data, and kinematics and compliance measurements, can improve performance parts design.

THE AFTERMARKET PERFORMANCE PARTS INDUSTRY developed largely on the empirical experience of its entrepreneurs- and then Federal Motor Vehicle Safety Standard (FMVSS) 126 came into the picture, which basically mandated the use of electronic stability control (ESC). Although most cars already were equipped with the technology before the 2011 OE deadline, the makers of suspension performance parts now are faced with “do no harm” compliance.

It isn't exactly proving a negative, because there is a very specific FMVSS 126 compliance test in the Federal Register. But the seeming complexity and cost directed industry trade group SEMA (Specialty Equipment Market Association) into action. It sought to create ways its members could develop suspension and braking parts, tires, and wheels, and affordably prove their products did not affect the OE systems' operation.
