It's not that simple. The amount of offset needed on the front is controlled by what sort of maximum front track you can get. If you already have sliding front hubs or have particularly long stub axles, you don't need a lot of offset.

Usually, people tend to use narrower rims in the wet, both front AND rear. The logic is that, as you will be using higher pressures, you need the side walls to have some 'give' in them. With wide rims, the side walls act more like 'buttresses'. Also, the narrower rim tend to bulge the tyre more around the centre of the tyre. Added to the higher pressures, this reduces the size of the 'contact patch' which aid water clearance and raises the temp of the contact patch (as so much LESS tyre is in use).

However, it all depends on what you MEAN by 'wet'. The range from 'damp track' to 'rivers across the track' require different approaches. One-size does NOT 'fit all' in that range.
