There are a couple of tracks in the Formula One calendar that are infamous for wet races.

Unsurprisingly, Spa-Francorchamps in Belgium is one of them!

So, let's take a look at what setup you should be using to be fast in the wet at Spa!

Aerodynamics

Belgium is a relatively fast track, so despite the rain, we can run a relatively low aero setup.

This means we've gone with a front wing value or 4 and a rear wing value of 7.

This should keep your speed high through the infamous Eau Rouge and Raidillon!

Transmission

We've got a rather typical wet setup as far as the transmission is concerned.

As such, we have an on-throttle differential of 50% and an off-throttle of 55%.

This should keep the car driveable throughout the lap, as well as helping to maintain grip in the low grip conditions.

Suspension Geometry

The speed of the track and few sharp corners means we can run a setup that focuses on straight-line speed.

For camber we have -2.70 on the front and -1.20 on the rear of the car.

With toe, we've gone with 0.06 on the front and 0.20 on the rear, which should help with that straight-line speed we mentioned earlier.

Suspension

This is where the setup differs the most from a dry setup. As such, we have suspension softness of 1 on the front and 2 on the rear.

For anti-roll bars, we've gone quite soft again with 4 on the front and 7 on the rear.

Finally, ride height is high at 7 on the front and 9 on the rear again.

Brakes

We once again have a very typical brake setup, which is designed around avoiding lockups in these low grip situations.

This means we have a brake pressure of 88% and a brake bias of 52%.

This should be a good compromise between stopping in a stable manner and avoiding lockups also.

Tyres

For tyre pressures we've gone with a relatively high wet pressure.

This is obvious in the 23.0psi on the front pressures and the 20.3psi pressures on the rear.

There is of course scope to lower these if you wish, however, your performance will likely suffer.
