Not that i am aware of. You have to DIY. A swooping arc towards the back on a piece of paper and then see how it looks like. Then cut out of lexaan or whatever.
Here is a picture of my peugeot MD so you can eyeball it a little.

Mikus paintwork
Great paint schemes on your 2 Peugeot 908's. Love the choice of colors.

Thanks. It is a RC10L2.5. I use dampertubes instead of sideshocks though. Even after 15 years it is still a capable car.

Hey guys, I have another noob question for you. Should I keep my setup symmetrical, and allow the tires to wear different, or adjust the setup so tire wear is even?
My track is clockwise and is often dominated by right hand sweepers that are rough on tires, so my front left tire is getting a bit coned, the right appears to be wearing flat.

Blow-over prevention?
I would imagine I'm not the first Pro10 racer to experience an unwanted aerobatic display at speed, and 9 out of 10 times the car usually slaps back down to earth with enough space left to save it before car/barrier interface...
But on the weekend my luck ran out!
It was a bit gusty in the wind department and at the sweeper end of the straight, leaves and all sorts of crap kept blowing across the track. I did a few warm up laps before my heat and went in there full throttle committed and ran over a twig or something just as I turned in, nose went up, car left ground, heaviest part (ass) went around then the lovely aerofoil shape of a 50mph backwards travelling Pro10 kept itself airborne all the way to the kerb then a lamppost...
Result was a broken rear axle, top section of motor pod, chassis brace, spurgear, rotor bent in motor and 1 saddle pack lipo split. I guess I am lucky it didn't burst into flames
Anyway, back to the question in hand - what tricks do you know to minimise the risk of a blow-over (other than slowing down of course!).
Has anyone ever tried creating a flat pan under the chassis sealing off the underneath of the body to avoid air being caught up in there? Or what about Nascar style flaps

John Stranahan Had a forum going for a while, and one of the first things he did was made a small air tunnel for the front of the car. Said it helped make a vacuum at the front end to keep the front down..
I was also told you need to have a big hole in the front of the chassis to make sure the air presure doesnt build up by the front axle. It wont help for a sudden burst of air under the car, but going down the straight it might.

Against the car going airborne like that, or as we call it on our local track "having a LeMans-Moment", there is not much you can do. As you said, you ran over a twig or something. It happens and usually you land on the wheels or in the grass, then you are lucky. You really just had a moment of bad luck, really bad luck in this case with all the damage but there isn't really anything to do against it.
I myself, when I am done marshalling I usually look on the track for twigs and debris and clean a little in my section. But with the wind doing his own thing, there is not much you can do...

John eventually found that the limited front suspension damping and travel cause blow overs when you hit a bump at high speed. You can apply his ultimate solution by going with a full on shock adsorber front end. Otherwise, you can add a small wing to the front of the body as many IMSA cars did, or drive around the bumps.
