Last week we had the pleasure of welcoming Seattle-based racing outfit The Heart of Racing to Catesby Tunnel. The American team, supported by Aston Martin Racing, race a Vantage AMR GT3 Evo in the World Endurance Championship, and it was the LMGT3 title challenger that paid a visit to the tunnel. The Heart of Racing also compete in the IMSA SportsCar Championship.

At Spa, which is a long lap, the top 5 LMGT3 teams in qualifying were separated by just 0.595 seconds, highlighting the importance of optimising setup and extracting marginal gains from the car. On the day of testing at Catesby Tunnel we were treated to some true English weather. The persistent rain, that would have wreaked havoc with any outdoor testing,  demonstrated immediately the advantages of testing at an environmentally stable facility.

The importance of these aero tests was heightened by 24 Hours Le Mans, the team’s next race, and arguably the biggest prize in endurance racing. Circuit de la Sarthe is a low-downforce circuit, meaning it features lots of straights and slow speed corners. With relatively few high-speed corners it can be afforded to sacrifice downforce in favour of reducing drag. But, by how much? Well, that’s what Catesby Tunnel is all about, providing a real-world and repeatable environment for aero mapping and setup optimisation.

“It’s fantastic to see teams racing at the pinnacle of endurance racing, utilising Catesby Tunnel to find performance gains that will translate on the track.”

Jon Paton, Catesby Projects Managing Director

The team also do a lot of fantastic work raising money for the Seattle Children’s Cardiology Research Fund, we wish them the best of luck for the rest of the season.
