Why Widebody Fitment Needs a New Approach
Wide-body kits, lip kits and one-off aero are now normal requests in Aussie and Kiwi custom shops. Customers want tight panel gaps and show-car stance, not rough edges and rubbing guards. To hit that level, the old mix of cardboard templates, tape measures and eyeballing is starting to show its limits.
Manual methods often lead to small errors that only show up once the car is back on the ground. You get uneven gaps, tyres catching on lock, or bumpers that need last-minute trimming. A modern 3D scanner for cars, paired with the right software and materials, gives you a digital copy of the vehicle so every part is designed to the real car, not guesses.
The full workflow runs from surface prep and scanning, through CAD surfacing and design, to print or CNC, then on-car validation before the final paint. It is a repeatable way to get OEM-style fitment, even on one-off builds.
Prepping the Car and Workshop for Clean Data
Good scans start with a tidy workspace. In winter, when daylight is short, consistent indoor lighting helps the scanner track surfaces. Try to:
- Control bright spots from open roller doors
- Clear at least a metre around each side of the car
- Keep floor clutter, cords and stands out of your walk path
On the car itself, set ride height and wheel offset as close as possible to final spec. Clean guards, bumpers and wheels so sharp edges read clearly. For tricky surfaces:
- Use a removable matte spray on glossy black, chrome or glass where needed
- Remove bolt-ons like mudflaps or splitters if they confuse the scan
- Watch out for very dark PPF or ceramic coats that may need extra care
The goal is a simple, clean shape that represents how the car will sit once the kit is fitted.
Capturing the Vehicle with Artec 3D Scanners
Handheld scanners like Artec Leo or Eva let you walk around the car and see the data build on screen. You can sweep over bumpers, guards, doors and especially wheel arches, including inner lips and undercuts that matter for widebody design.
Common scan paths for local builds include:
- Street cars, following the lower body line and arch edges
- Lifted 4x4s with bullbars and flares, working around bars and steps
- Time-attack cars with splitters and diffusers, capturing underneath areas
- Utes with canopies, scanning tray edges and tailgate alignment
On-the-spot QA is key. Check the live model for gaps, soft edges or missed zones like door shuts and mounting faces. Rescan anything suspect while the car is still in the bay.
From Raw Scan to CAD Surfacing
Once you have solid scan data, bring it into reverse engineering software. Clean loose noise, align any multiple passes, and trim away areas that do not matter so you are left with a tight shell around the kit zone.
From here you can:
- Build reference planes, symmetry lines and section cuts
- Lay smooth surface patches over the mesh for guards and bumpers
- Create mounting faces for brackets, wings and diffusers
With a digital twin of the car, you can check tyre sweep at bump and lock, exhaust clearance around a new diffuser, or space behind a custom bumper for ducting or intercoolers, before a single part is made.
Prototyping, CNC, and On-Car Validation
When the design is ready, export the kit parts for real-world testing. Many shops will 3D print test-fit arches, lips or inserts in tough engineering polymers or composite-filled materials. Others will CNC foam bucks or moulds that later become fibreglass or carbon.
Then comes the on-car loop: bolt on the prototypes, cycle the suspension, check full lock, mark any tweaks back into CAD and print or machine the next revision. This process is especially handy as builds ramp up for summer shows and track days, when deadlines are tight and rework is painful.
Choosing a 3D Scanner and Building a Repeatable Workflow
When picking a 3D scanner for cars, think about:
- Handheld freedom versus fixed rigs
- How it handles dark paint, wraps and lifted 4x4s
- Accuracy around panel gaps and mounting faces
- Colour capture if you want visual references on-screen
Artec 3D scanners are well suited to custom and motorsport work, giving fast capture and clear feedback that fits shops without full-time metrology staff. With the right support, your next widebody or kit can become the master project that builds a library of CAD, scan data and toolpaths. That same data can then be adapted for repeat kits, new wheel specs or interstate and New Zealand customers, turning one-off success into a standard way of working.
