This NSB (Never Seen Before) shifter is our complete redesign for the Audi A4/S4/RS4 platform. The original Coolerworx shifter for these cars was released back in 2015 and served thousands of customers around the world. It worked well, but we always knew we could push the design further — make it easier to install, better to use, and more solid overall.

In 2025 we decided to redesign everything from zero and build a proper, modern shifter for the B6–B7 chassis.

The Story Behind It

For this new model we bought an Audi B6 and fully 3D-scanned the center console. This let us engineer the parts with high level accuracy and design the shifter exactly the way it should be.

One of the biggest issues with the old design was installation: the mounting plate had to be installed from underneath the car, which meant dropping the exhaust, removing the prop shaft, and taking out the whole OEM shifter housing. We wanted a better solution.

So we created a new CNC-machined adapter plate shaped exactly to the tunnel’s contours. Now the entire shifter can be installed from inside the car. No cutting, no trimming, no butchering any interior parts.

What We Changed

We didn’t reuse any parts from the old Coolerworx Audi shifter. Everything is new:

- new handle
- new tower/frame
- new mechanism layout
- new geometry
- added self-centering spring

Because the mechanism sits higher, we also designed a custom plastic cover (based on the 3D scan) that fits exactly where the OEM leather boot was. Clean, simple, OEM-friendly.

Engineering and Feel

We tested around 20 different handle ratios to find the exact one that suits the B6–B7 6-speed gearbox.

It’s not designed to be the shortest throw possible — it’s designed to be the right throw, with the right leverage and the right mechanical balance.

The final result is a shifter with a clean, precise, metal-click engagement that feels better than ever before.

It’s solid, direct, and gives you a proper mechanical feel every time you shift.
