took me well over a year to get used to my sierra with an open diff all i say is drive with care in the rain coz if you dont it will bite ya in the ass and youll be hitting the cerb have some fun aswell when knowone is around, learn the way the car steps out then when it does go sideways you dont just panic and lose it you have a little bit of a headstart on what its going to do but imo rwd in the rain sucks but can be very fun
