What to change in wet weather setups?

Since I have now done a couple of endurance mini races in changeable (or very wet!!) conditions, and there is another one coming up tonight, I was wondering what advice anyone could give or what should be changed from a dry setup to a wet one?

I be guessing at something like:

  • softer tires / less pressure
  • softer anti-roll / springs
  • softer bump/rebound
  • maybe knock the gearing back a little
  • ...softer all round I guess :wink:
EDIT: Admins can you change the title to "change" instead of "chance" ... although "chance" would be right in my case :lol:

thats about it, i would add break bias and break pressure and your driving, changing your braking point also is a good thing.

In the E46 i tend to put the brake bias around 57:43 and turn the pressure down to about 75 or 80 to stop the brakes from locking up. Works quite well with the E90 aswell, but in that you may want a bit more bias towards the front.

On the Mini, i set the braking pressure to 80%, but the most important i increase the toe in (-40 in front and +60 to the rear). So I reduce the gears ratio. Those are the only things which I change with regard to my dry setup. :thumb:
