Wet set up tips
mikeb - 12/5/11 at 01:01 PM

I'm racing this weekend at snetterton its likely to be dry practise wet qual or race.
We have our dry set up nearlly nailed to give us podiums.
But we've not run this car in the wet.
Its a caterham with LSD

i have a list of changes to make.
Tyre pressures (new set, higher cold pressures)
Camber angles
Roll bars (front and rear off or just rear and run the softest front)
Changes in toe to get a bit more heat into the tyres or leave it more neutral as we don't need it too twitchy in the wet.
Ride height and Rake angle?? lower rear?

Any tips, if we had a wet practise I could get it sorted but I have feeling we are not going to be that lucky!

Brake balance - slightly more rear.

fogot to list this one.
The logic is to stop the fronts locking into the corner,
I guess the downside is loosing the back end under heavy braking?

With the cars I have raced the balance bar generally required exactly 1 turn to rear between wet and dry but that was using proper slick and wet tyres respectively, err on the side of caution to much rear has more potential for disaster.

With less grip there's less weight transfer so less chance of the rears locking. Hence you can up the rear brake effort.
