Trackit in Action hero banner: Digital Auto Body Kit Development, SHIN-GI's high-precision, high-efficiency approach

The Challenges Facing the Development Team

In body kit development, it is essential to capture not only the overall shape of the vehicle but also the mounting positions and reference points of each part with high precision.

Traditionally, the process involved manually measuring each vehicle one by one and fabricating and refining clay models to finalize the shape. However, this method made it difficult to ensure left-right symmetry and required repeated fittings on the actual vehicle, demanding significant time and effort.

Even when scanning large vehicles with a typical handheld 3D scanner, the need to attach markers, spend long periods on alignment, and merge scan data all became factors that limited development speed.

How Trackit Transformed the Development Workflow

To solve these challenges, Studio FinalTAKE adopted Trackit.

In the early stages of development, Trackit is used to capture the vehicle's overall exterior data along with the layout points needed to mount parts.

Because Trackit supports markerless optical tracking, there is no need to attach large numbers of markers to the vehicle body as before. Even with large vehicles, high-precision 3D data can be acquired quickly without worrying about positional drift.

The acquired 3D data is imported directly into CAD to design the body kit. From there, CFD analysis is used to verify aerodynamic performance, and the shape is refined to balance both design and functionality.

The completed CAD data is then used to produce prototypes with a 3D printer, or to manufacture finished products in FRP or CFRP.

By building this end-to-end digital workflow — "Scan → CAD design → CFD analysis → Prototype → Manufacture" — the team has significantly improved both development efficiency and product quality.

The Impact of Adopting Trackit

Adopting Trackit has driven a wide range of improvements on the development floor.

First, being able to digitize an entire large vehicle quickly and with high accuracy has drastically reduced the time needed for initial data capture.

Since the captured 3D data can be used directly in CAD design, left-right symmetry and part-fit accuracy can now be guaranteed digitally. As a result, the process of repeatedly test-fitting prototypes onto the actual vehicle has been greatly reduced, shortening the overall development timeline.

In addition, with less need to attach and remove parts on the actual car, the risk of scratches or damage to the customer's vehicle has been lowered. This is a major benefit not only for developers but also for the owners who entrust their prized vehicles to the team.

Trackit's Strengths in the Field

What Mr. Takeda values most is Trackit's ability to scan large structures with high precision, completely markerless.

A single scan captures not just the entire body of the vehicle, but also sharp edges and the fine details of mounting points, allowing broad body geometry and localized structural information to be acquired at the same time.

Trackit is also a powerful tool beyond body kit development, particularly for on-site measurement of large structures.

For large structures, checking overall distortion and hole-position accuracy is critical, and Trackit makes it possible to visualize and verify those factors with high precision.

Customer Testimonial

"The greatest strength of Trackit is its ability to scan large structures with this level of precision, completely markerless. In a single pass it captures broad body geometry as well as fine mounting-point details, making it indispensable for body kit development."

Mr. Takeda also recalls that "in the past, we had to attach a huge number of markers to the entire body, and just removing them afterward took a significant amount of time."

He values Trackit's markerless scanning not only for improving work efficiency but also for reducing wear on painted surfaces — a significant benefit in the automotive industry.
