WHAT'S INCLUDED Full rear diffuser assembly for the 4th Gen Mazda 3 Sedan, consisting of the main diffuser body, side extensions, and rear spats. Designed from the ground up using precision 3D scans of the actual vehicle for guaranteed fitment.

MANUFACTURING Every component is 3D printed in-house using ASA (Acrylonitrile Styrene Acrylate) — an engineering-grade thermoplastic chosen for its superior UV resistance, thermal stability, and structural rigidity compared to standard PLA or PETG. Parts are printed at high density for strength and designed with assembly tolerances built in.

AVAILABLE IN TWO OPTIONS

DIY Unassembled Kit — All components shipped flat, unassembled. Ideal if you want full control over the build and finishing process. Requires assembly, bodywork, and paint.

Pre-Assembled — Delivered fully assembled as a single unit, ready for bodywork and paint.

Both options ship in raw 3D printed finish. This is not a plug-and-play painted part. The kit is designed to be finished by a body shop or experienced DIYer — expect sanding, filling, priming, and painting before installation.

WHO THIS IS FOR Builders who want something that doesn't exist anywhere else. This kit was designed, scanned, and built entirely in-house — not sourced, not generic. If you want a factory part, this isn't it.
