Thats definitely part of it, Steve has done a great job.
The track had very little grip, Willowbank is bit like Phillip Island in that the grip varies an aweful lot from temperature & what has been running there before.
Thats not too bad for this time of year, I wouldn't expect to make it into the 10's until some more cars have run & it's cooler. We'll be looking to break the DJR lap record there at a test April, if not the one before Willowbank.
At the end of the day your benchmark is the other teams running there, and we were quite happy with the result of what was basically a shakedown test.
