Alright guys...stop the "you got more torque now" comments. This is a legitimate safety question and you are not helping.
I have a 96 with 4.10's. It has been raining alot here lately and I do all sorts of driving from city stop and go to Interstate. The only thing it takes, like at the track, is practice. Problem is if you mess up during practice here you can get hurt. My suggestion is the next time it rains and you have free time take a spin through a quiet neighborhood or an empty parking lot. Find out how much gas you can safely use to take off, what is safe around corners and turns, and how much brake you can use for stops. I have found that sometimes taking off in 2nd gear is better for wet roads. If you find yourself breaking loose just release the gas and the car will right itself. Alot of times people will make a drastic movement in steering and then are toast. I have hit patches of water on the highway that caused my car to feel like it was about to fly off the road but you let the car drive through it with very small movements, if any at all, of the wheel. Your car will find traction soon enough although you will feel like it is an eternity. Point is that the more you do it the better off you are and the safer you feel. And the 25+ years I've been driving helps.
