Yeah we were. That was the only stage we had the centre diff working. All the other stages it was overheating and blowing the fuse. It held out for 4 laps of Barnard Park though. When it's all working as it should be the car is great to drive, so balanced and predictable. Without the centre diff control it stays out sideways too long and too far, wastes time and is always in the gutter risking rear bumper and tyre damage. The other thing that was in the back of my mind was the potential to break a driveshaft and be stranded where we would usually lock the diff and limp out of stage to service and continue.
