That is a serious splitter, you are going to get much better front end grip out of that!
Yes. I think Zozzy has posted here, first time out with one he knocked off a 12 year old lap record, with no testing and the wing set at 0 deg.

I misread a post on your thread as you starting a new wing, it was someone else said that. If you have access to McBeath's profiles, the 132 would be the better profile than that one if you do start a new wing. If you don't, the S1223 would be my pick but I would be interested in any other suggestions from other people.
COT would be another option, but unless you buy one, as far as I can see nobody really knows what profile it is, there are a few guesses but nothing definitive.

I started the day with the wing at zero degrees, and kept increasing AOA until the rear edge of the wing was slightly above the end plates. After that, I drilled new holes in the front to lower the front edge to increase the angle to 12 degrees. Top speed dropped about 3mph. But it set its fastest lap time of 1:43.8. Equal lap time to many big dollar V8 race cars.
The pics are from the morning at zero degrees angle. The front springs are more compressed than the rears, so the front splitter/undertray is working very well. Last lap in the last session - the front splitter mounts let go. The bolt heads ground away underneath causing the right side to be unsupported, then the middle alloy tube snapped at where I bent it (weak point) from the extra weight on it. I have a solution, and will have it ready for Saturday.

Good to see the addition in the front prove itself for you. I hate trimming out rear downforce just because there isn't enough in the front to capitalize on it. That 3 mph loss at the top is verrrrry worth it. Make stronger mounts, continue winning.

Well done, congratulations!!! I look forward to the video, especially the bit around Lukey!
I am surprised that you only lost so little top speed. What was your baseline, and was that at max AoA?
Are you planning on changing the front springs, or otherwise stiffening the front end, to reduce the rubbing? Maybe just a rubbing block in front of that attachment if time is short?

Lukey is fun, it still has the *** hanging out if I push it a bit too far. It's fun. I haven't seen the video myself yet. I must get onto that. I hope the video looks as exciting as it feels from the drivers seat.
Starting with the wing at zero, I actually picked up speed at around 5-6 degrees. There was a tailwind that may have influenced the data. But it wasn't that windy. And if anything it should have kept the same speed, as the tail wind would have canceled out the extra drag.
Spent a bit of time today making camera mounts under the car, and some measuring devices. So come Saturday we should have a lot of info.

I thought as much.
I guess I will keep hunting. Bizzare that something so readily available in the states, just doesn't seem to exist over here.
I have even called a bunch of plastics suppliers and while they do HDPE sheeting, they dont have any flexible enough to be rolled.
Thanks

3mm sheet of this then?
Polyethylene Sheet HDPE 2mm-3mm-4mm-5mm-6mm-8mm thick
Even if they don't normally shop in rolls you can probably ask them to roll it up for shipping.
The 2mm roll I have would probably work as a airdam with suitable support (it's not flimsy by any means), but a thicker one would be sturdier of course (and give a smoother look).
It's working well for generic patchworks though
