ACS Composite Canards - C8 Corvette Grand Sport and Grand Sport X
The ACS Composite Canards, part [50-4-172]CFZ, are a molded PC composite pair that bolt to the inner fender and the front splitter of a 2027 C8 Corvette Grand Sport or Grand Sport X. They are cut for the factory Aero Package splitter, RPO T0F, and for the ACS splitter [50-4-158]CFZ, and they are finished in Carbon Flash Metallic Black.
Here is the part worth knowing before you buy anything else for the nose. The factory Aero Package gives your car the front splitter and stops there: GM omits the canards from delivery. That is why the front corners look unfinished next to a track car, and it is the gap this pair closes. Set at the outer edge of the splitter, they turn air outward around the front wheel instead of letting it pile into the corner, which is what the c8 corvette aero pieces above them are already doing further back. Owners searching c8 canards are usually looking at exactly this shape.
