Engineered parts.
Built for the track.
We design and manufacture custom racing parts for Mazda, Caterham, Matra and more — 3D printed, CNC machined, or engineered from scratch.
What we do
From rapid prototyping to precision machining, we cover the full range of parts your build needs.
3D Printed Parts
Custom FDM parts in ABS, ASA, PA-CF and PC-CF built to survive the track.
CNC / Billet Parts
Precision milled and turned parts for when FDM just isn't enough.
Engineering
From sketch to CAD to finished part — we design what you need.
Electrical
Custom PCBs, harnesses and CAN integrations for modern data logging.

What people say
A few words from the drivers and teams we've built parts for.
"Shiba Performance installed a MaxxECU Race with PNP on my Nissan S14. On top of that, he made me a custom wiring harness for the addition of a flex-fuel sensor, IAT, and a Bosch oil pressure/temperature sensor. A wiring harness for the installation of R8 coils and the connection of a Hall sensor in place of the original CAS. Everything works perfectly and allowed me to drive my S14 again after a long period of troubleshooting with the old factory ECU."
