Keith and Karl Brooke have comfortably taken out the Shannons Thoroughbred Trophy title in their 1980 Porsche 911.

Brett Dillon and co-driver Geoffrey Corah in a 1968 Porsche 911 were able to marginally reduce the gap in the opening stage of Day 3, but after accumulating penalties on Day 2, it was always going to be a mountain too high to climb to chase down Team Brooke.

In the end the Brooke combination drew further ahead and eventually finished 22 minutes and 41 seconds clear of their class rival.
