ACS Composite Front Splitter - C8 Corvette Grand Sport and Grand Sport X
The ACS Composite Front Splitter, part [50-4-158]CFZ, is a single piece PC composite splitter for the 2027 C8 Corvette Grand Sport and Grand Sport X, coupe and convertible. It mounts to the factory front fascia with the hardware supplied and is finished in Carbon Flash Metallic Black, and it goes on with no drilling and no modification to the car.
Every splitter argument is about downforce and almost none of it is about the driveway. The shape is cut to increase frontal downforce for grip and stability through turns, which is the reason to fit one, but a c8 corvette front splitter that grinds itself away in a season is a consumable rather than aero. That is what the nine skid plates along the underside are for: they meet the concrete first and they wear instead of the splitter. Owners shopping a c8 corvette splitter compare profiles and finishes; this is the one whose underside was designed to be dragged. It is also the 50-4-158 the ACS canards are cut to sit on, so the c8 corvette aero at the nose can be built in two steps.
