This listing provides a high-resolution 3D CAD model of a ZCar-style Mini space frame chassis designed for rear-mounted K20 VTEC engine conversion. The model captures the full structural layout including chassis rails, mounting points, suspension pickup geometry, and integrated body panel interfaces, making it ideal for custom fabrication, swap development, and motorsport-oriented builds.
The design is based on a space frame architecture intended to accommodate a transverse Honda K20 VTEC engine in a mid/rear-engine configuration. It includes integrated provisions for body panel alignment as well as a built-in roll cage structure.
The model is provided for engineering and visualization purposes, supporting CAD-based development, packaging studies, and fabrication planning workflows.
Compatibility
Designed for custom Mini-based space frame builds utilizing Honda K20 VTEC engine swaps and rear/mid-engine conversions (professional verification and adaptation required for individual builds).
Common Applications
Custom chassis and space frame design
K20 engine swap and drivetrain packaging
Suspension geometry and pickup point development
Body panel integration and fabrication planning
Motorsport and track-focused build development
3D visualization and engineering simulation
Common Vehicle Applications (Real-World Use)
Custom Mini-based space frame builds
Mid-engine K-series swap projects
Track-only and hillclimb prototypes
One-off motorsport fabrication projects
File Contents
CAD model (format as provided)
File Suitability
Ideal for advanced CAD workflows including chassis design, fabrication planning, and vehicle concept development.
Important Notes
Includes integrated roll cage structure; however, we cannot guarantee structural performance, crash safety, or compliance with any motorsport or road regulations.
This design is intended for reference, development, and visualization only.
All structural and safety-critical elements must be independently validated by a qualified engineer or fabricator before use.
Final build requirements may vary significantly depending on application and governing regulations.
Disclaimer:
We encourage you to review provided images and any available sample files to assess quality, structure, and compatibility with your workflow. Different CAD software may interpret assemblies differently, so validation within your environment is essential.
While every effort is made to ensure accuracy, we strongly advise full engineering verification before using this design in any physical construction, especially for load-bearing or safety-critical applications.
