![]() ![]() FRS rear spats can maintain the effect of a side splitter throughout the length of the car or aid the effect of the diffuser. Wings, spoilers, diffusers, splitters, dive planes, vortex generators, and spats work together as a system to accomplish these goals. Less turbulent air, “cleaner” air, improves the effectiveness of the airfoil. Quick explanation for those of us that played Halo on the computer during high school physics: downforce is created by creating low pressure areas on one side of an airfoil (high speed air), while simultaneously creating high pressure areas (low speed air) on the opposing side. Successful race-oriented aerodynamic enhancements will increase downforce, reduce drag, or increase the effectiveness of other aero additions. Like splitters and skirts, rear spats influence the behavior of atmosphere around the vehicle. Like any aero component, spats are bred from function. The BRZ and FRS have been welcomed with loving arms from the aftermarket aero enhancement community, as the increasingly popular platforms simply belong amidst the be-winged attackers of time. Not to be confused with rear wheel covers of similar nomenclature from the malaise era, rear spats are fitting in a culture that is increasingly interested in aerodynamic improvements and track-oriented performance. Regardless of my understanding of the etymology of the term, rear spats have become a fashionable accessory for many modern tuners. It is an incredibly UK-spec word and I am incredibly from the southern United States. The exact history of how the popular aerodynamic additions became known as “spats” is somewhat of a mystery to me. ![]()
