964 Custom Carbon Fiber Body Backdate //

Custom front longhood and Rear 964 lenses


A fully custom carbon fiber body backdated 911 requires front and rear lenses worthy of the custom design of the rest of the car. Starting with 3D Scans of the custom body panels and stock rear 964 housings we embarked on a design journey to create lights worthy of a truely custom build. 


Fully Bespoke Lights – With non-standard front openings and 964 rear housings on a backdated car we had to start from scratch to design and produce lights that feel vintage correct and work with the aesthetics.

Modern Process for Classic Design – 3d Scans, custom CAD design and 3D printed testing made the development process a seamless experience from concept to production.

Custom Watch Inspired Gauges


As this build progressed our client discussed inspiration from his love for watches and how we could incorporate it into the build. We set out to design truely unique, one-of-a-kind gauges that fit the rest of the car and would be a showcase in this special build.


Custom 3D Design Elements – Not willing to settle for flat gauges we designed and made 3D elements to compliment the design.

Full In-House Customization – None of the typical gauge builders were willing to take on such an ambitious vision, so we customized them in-house.

Jeweled Centerpiece – The gauges have become the centerpiece of an overall amazing build, drawing viewers in to see the details come to life.

Custom Center Console


As part of a full backdated interior project, our client wanted a unique center console that would seamlessly match the style of their selected seats and tie together the custom interior. We began by performing a full 3D scan of the bare floor and tunnel area, using 3D CAD to guide the overall design, feel, and precise fitment.


The result not only adds a more refined and finished look to the tunnel but also integrates functionally, with the console including cup holders and relocated controls, enhancing both aesthetics and practicality.


Seamless Design Integration – Matches the style of the seats and unifies the entire custom interior.

3D Scanning & CAD Design – Full 3D scan of the floor and tunnel for precise fitment and a polished final look.

Enhanced Aesthetics – Provides a more finished and refined appearance to the tunnel area.

Functional Upgrades – Includes cup holders and relocated controls for improved functionality and convenience.
