Check out the wool tufts on the wing. I wool tuft tested all the bonnet vents, then i did fastback, and the wing. everything checked out really well with attached flow, and in the direction i expected. The wing worked so well, beyond what i could have imagined. Need some front aero now. Massive understeer all day. You can see in the pic i dropped the aoa down as low as i could get it to get some steering back.

Did you notice any difference in top speeds by comparison to your old hardtop/wing setup.
Does the new layout favour higher straight line speeds, by staying lower and using the coupes shape to apply downforce?

I have never done winton long in this car, so have no previous data. But i compared my speeds to brendans data in the first sessions. And all speeds where higher, including the max speeds at the end of straights. The fastback was helping to keep the air flow smooth. When Brendan uploads the video with data you will see it bottoming out on the sweeper. Rough ride, but stuck like glue to the track.

Video footage is up on Mazda Australia's YouTube page of the Phillip Island 6 hour, specifically of the start of the race from Dave's car. Footage is all thanks to Ben Sale http://www.othersideproductions.com

There's a little bit of fancyness in the video which allows you to choose your camera angle... here are all 4 angles:

Thanks for doing that.
On the sat practice run I was battling it out with that mustang. There would have been some great footage, as I was within an inch of his rear bar several times. There was a lot of cars behind me at the start of the race, felt good to be right up the front.

I am uploading one more video now of the Phillip Island 6hr.... will post it up in the next hour or so.
Then, I'll start on the Winton video from last weekend.
