Shadow Circuit Marauder

220mm-projection front splitter with outer dive planes and braced mounting points
Dual vertical radiator inlets plus auxiliary corner ducts for cooling and tire wake management
Hood: raised center ram-air box with triple slots plus twin rearward NACA heat extractors
Rear diffuser tunnels integrated into bed-cover extension with five vertical fins
Adjustable dual-element GT wing (1700mm span) on tall carbon pylons with endplate detailing

This is an elevated-highway time-attack fantasy rooted in real constraints: short pulls, hard braking, and quick direction changes on imperfect pavement. The aero and cooling choices read like they were made for predawn runs—high-speed stability, brake temperature control, and predictable front bite despite the truck’s frontal area.

Volk Racing TE37 SL forged: 20x11 front (ET15), 20x14 rear (ET5)
Toyo Proxes R888R: 305/35ZR20 front, 335/30ZR20 rear
Brembo big brake package: 6-piston front, 4-piston rear with slotted/drilled rotors
Widened track: +270mm front overall, +310mm rear overall to match flare coverage

5.7L Hemi rebuilt with forged rotating assembly for sustained high-load pulls
Reworked intake path fed by hood ram-air box; calibration aimed at repeatability over peak numbers
Upgraded cooling stack with high-capacity radiator and ducted airflow management
Flush side-exit exhaust behind the front wheels to reduce rear heat soak and keep plumbing short

Overfenders tied into a welded tube extension structure rather than relying on adhesive mounting
Splitter and dive planes designed around serviceable wear surfaces and replaceable edges
Bed-cover diffuser tunnels built as a composite assembly with reinforced fin bases to resist vibration
Ducting designed as sealed pathways (inlet-to-core and inlet-to-brake) to avoid “open-mouth” inefficiency

Shadow Circuit Marauder is what happens when a 5.7 Hemi Ram stops pretending it’s a straight-line bruiser and gets rebuilt for midnight expressway apexes. The silhouette stays unmistakably Ram—high beltline, blunt nose, big shoulders—but everything around the wheels and under the bumpers is re-authored with Japanese time-attack logic: track width first, aero second, cooling always.

The widebody isn’t cosplay; it’s structure. Tubular extensions push the front and rear tracks out into TE37s and R888Rs, while a splitter that actually projects, a bed-cover diffuser, and a tall dual-element wing turn a brick into something that plants at speed. It’s street-adaptable in the way real street time-attack cars are: adjustable, overbuilt, and unapologetically loud in function even when the paint stays stealth.
