Sisu Performance Labs Racing Team

After more than a decade as Underbite Racing, we’re retiring the name. Starting January 1, we’ll compete as Sisu Performance Labs Racing Team.

By partnering with Sisu Performance Labs, a new endurance coaching venture, we’re embracing the Finnish concept of “sisu” - unyielding grit and determination in the face of adversity - while reinforcing the link between physical preparation and motorsport performance.

Watch for a fresh livery on car #199, and follow both Sisu Performance Labs and Sisu Performance Labs Racing Team for updates.
