Sisu Performance Labs Racing Team

Mimi was back in action a few weeks ago… so happy the new owners will be turning her into a track toy!

There’s been some progress over the years… I’ve really enjoyed the learning curve associated with racing - the car prep, the driving, and (less so) the occasional repair work.

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.
