The Youkai

1550mm matte carbon splitter with dual dive planes per side
Ducted front brake cooling through fender recesses and internal carbon channels
Full-width rear diffuser (7 fins) integrated into widened rear bumper line
Hydraulic dual-element rear wing on tall carbon pylons with adjustable AoA

Set for wet, neon-lit street circuits where bumps, paint lines, and short straights punish unstable setups. The lowered ride height, stretched wheelbase, and big staggered tire package focus on confidence through fast direction changes and repeatable brake zones—exactly where a heavy platform has to earn its lap time.

Volk Racing TE37SL: 18x10.0 +45 front, 18x11.5 +55 rear
Toyo Proxes R888R: 285/35ZR18 front, 315/30ZR18 rear
Aggressive alignment target: increased front negative camber for turn-in, rear set for traction and stability
Big brake package with dedicated ducting and caliper shrouds for repeatable laps

3.6L Pentastar V6 shifted rearward ~130mm for improved front axle load and rotation
Sequential 6-speed with motorsport-style control logic for rapid, consistent shifts
AWD conversion with center differential and torque-vectoring strategy for corner-exit drive
Split cooling: main radiator up front, auxiliary oil/trans coolers in ducted sidepods

Composite flare layup uses carbon for stiffness with aramid reinforcement at edges and fastener zones
Internal ducting built as sealed carbon channels to prevent pressure bleed into wheel wells
Diffuser and rear quarter integration designed as one continuous underbody exit to reduce separation
Wing pylon backing plates tied into hatch structure and rear reinforcement to manage bending loads

The Youkai starts with the most unassuming platform in the paddock—a 2013 Grand Caravan—and drags it straight into the midnight time-attack lane. The roofline and glass stay unmistakably van, but everything below the beltline is re-authored: a +180mm/+200mm track swell wrapped in carbon/aramid flares, a hard-edged front clip with real brake ducting, and a splitter you can measure with a tape—because it’s doing work, not cosplay.

Under the demon vinyl and satin obsidian/red pearl, the engineering reads like a serious street-circuit weapon. The Pentastar is pushed back toward a front-mid layout, cooling is treated like a system (not a single big opening), and the chassis is set up to put 285/315-section rubber to the ground with stability. It’s a family hauler silhouette with the stance and aero vocabulary of a night-run time attack car—built to look wrong and feel right.
