ABOUT US
Motorsport Design & Engineering
Closed Loop Racing designs and manufactures precision 3D-printed parts for motorsport applications. Backed by over 12 years of engineering experience, we exist because the parts we needed didn't exist — or were overpriced for what they were.
Every part starts as a problem on a real car. We design in professional CAD, prototype rapidly, test on track, iterate, and only then offer it for sale. If a part doesn't survive our own abuse, it doesn't make the catalog.
We're committed to high quality — every product is our own original design, engineered with proper tolerances, material selection, and print orientation for the intended application. All parts use brass threaded inserts for durable, reliable hardware connections that won't strip or wear out.
OUR PROCESS
1. DESIGN
Parts are modeled in professional CAD with engineering tolerances. Designed for print-in-place with brass threaded inserts for all hardware connections.
2. PRINT
Printed on calibrated machines with engineering-grade filaments. Material chosen per application: ASA for heat and UV, PETG for impact, Nylon for flex and fatigue.
3. TEST
Every design is tested on our own cars in real conditions — track days, autocross, and daily driving. We iterate until it's right.
4. SHIP
Parts are printed to order and inspected before shipping. No warehouse of aging inventory — fresh prints with current revision designs.
WHY 3D PRINTING?
Modern engineering-grade 3D printing materials rival injection molding for many automotive applications. ASA handles 200°F+ engine bay temps. PETG absorbs impact without shattering. Carbon fiber composites match aluminum for stiffness at a fraction of the weight.
The real advantage is iteration speed. When we find a fitment issue or a better design, we update the CAD and the next print is the new version. No tooling costs, no minimum order quantities, no warehouse of obsolete parts.
This means every part you buy is the latest revision — designed, tested, and improved by people who actually run these parts on their own cars.
