I had the afternoon off so I've been going through most of the cars at Monza in similar conditions to the storms last night. I've made some very basic changes to the default wet setups to try and help the cars cope with that level of rain better. I didn't spend much time on them so they wont be a magic bullet but they should be an improvement. I did try some of the defaults and they weren't awful. The Audi and Merc had a bit of trouble at Curva Grande. The brake bias on the Merc is a very long way forward and the abs isn't at max so that could improve that.
The biggest differences came from tyre pressures, they need to be at least 30 psi. It's better to be higher than lower. Also Aero balance rearward helped a bit as well, so raising the front relative to the rear and adding rear wing are the main things to help with that. Full TC is pretty much mandatory, I got away with less in the 720s and porsche. Its a huge help in the puddles. I think that's part of the reason why the Lambo is the hardest to drive, The TC on max doesn't seem to cut in as quick once the wheelspin kicks in. I found running that on max power was better than the wet maps because it made the wheelspin happen fast so the TC activated quicker.

Theres also some Motec from a run in the Lambo in that.
Few notes on some of the cars.
The NSX and Merc are bad for locking in t1. The NSX has to brake really early, well before the 200m board to make the corner.
The Ferrari is tricky at the start but seemed to come good as the tyres heated and came up to pressure.
Theres a big spread laptime wise over the field. The fastest were the lambo and 720. They did high 2:10s. The rest of the cars were spread over 4 seconds. Easiest to drive was probably the Aston, it was also pretty quick.
The biggest thing to remember is not to lift once the car gets loose on a straight. Lifting puts the weight over the front which gives it more grip and less at the rear which will make you spin faster. Keep your foot in and hope the TC sorts it out. Entering a corner like Curva Grande make sure youre already slowed down enough, ~170 for that one, and then keep a bit of throttle to keep the car balanced. As long as its not aquaplaning the TC and slight steering adjustments should keep you out of trouble. During braking slam the gears down as fast as you can. Engine braking seems really effective in the wet and I haven't blown one up yet.
Another trick you can use during the corners sometimes is to turn much more than you need into a corner. Doing this overloads the front axle and puts the car into understeer. It will keep the car from oversteering if you need to be off throttle during turn in. If you're going to do it don't turn only a little more than you need to, theres a pretty solid chance the front axle will grip up as you slow down and then it will snap, make sure you scrub the tyres a lot.
Heres a vid from a run in the 720 and the Hurracan Evo. Should help explain everything a bit more.
Think that's everything...
