According to the official CCP Fabrication product lineup, these lightweight hardtops are constructed from high-quality fiberglass or optional carbon fiber/Kevlar composites. They feature a streamlined aerodynamic profile that extends all the way to the rear decklid, replacing the factory trunk layout. The kits are shipped securely packed in foam and bubble wrap as pictured, and include a separate Lexan window opening, specialized side seals, and an installation instruction packet.
