Universal Brake Duct

Scalable-mouth front brake cooling duct with a fixed hose collar. Four mounting styles: side zip-tie ears, top zip-tie pads matching the Fusion original, bolt-through tabs, or bare.

Hood / Fender Extractor

Raked louvre panel that vents hot air out of a hood or fender. Bends to sit on a curved panel. Countersunk fasteners sit flush with the outer face.

NACA Submerged Duct beta

A flush intake that takes air from a surface with nothing protruding into the stream. The ramp walls diverge along its length, which rolls a pair of vortices that drag the boundary layer aside so the ramp can reach clean air — the feature that makes a submerged inlet work rather than just being a hole.

Universal Rear Diffuser beta

A rear diffuser from numbers you can measure off your own car: how wide the floor is where the diffuser starts and where it ends, how far it runs, and how high its two ends sit above the floor line. Strakes are laid out from a nominal channel width and rounded to a whole count, the outer pair can be full side walls, and the trailing edge can carry a lip. The preview shows it as it sits on the car, strakes down and tail up; switch the orientation to flat before you export and it lies body-side down on the bed with nothing overhanging. Like the splitter it is cut into tiles both ways, with dovetails, and the cuts across the car always land in the middle of a channel rather than through a strake.

Splitter Extractor Cowl

Bolt-on undertray extractor: a flat countersunk flange with a single smooth swept cowl rising off it into one large tunnel-shaped exit. Vents the high-pressure region under a splitter or flat floor out over the flange's trailing edge.

Universal Front Splitter beta

A front splitter generated from a handful of numbers you can measure off your own car. It spans the whole range from a bolt-on lip that follows the bumper to a full front undertray the bumper sits on top of, with the nose arc as its leading edge, squared outer corners, and a notch cut out of the trailing edge to clear the crash beam or subframe. It can cut openings for the Splitter Extractor Cowl straight into the floor, drilled with that part's own bolt pattern, so the two bolt together. Because no printer has a 1.4 m bed the board is cut into tiles both across the car AND fore-and-aft; each tile carries dovetails on the joints it owns and the matching sockets on the others, so joined tiles cannot pull apart sideways.
