So Formula Drift has revised the track layout for Irwindale Speedway, the new track is said to encourage more tandem drift action, but it is not a real dramatic change. But the new course is shorter and cuts one of the best sections in the whole course by ending in the middle of what was the final S turn.
Below are the two course side by side. (old course from previous press materials)
While it is not a big change it will mean we can't get photos like this any more in the final turn.
