I've raced the past few years with an open diff (ITA crx) and am planning on using a welded diff for the upcoming season.

I likely won't have much opportunity to practice with it beforehand, so I'm wondering how my driving technique will need to be altered, and what to watch out for.

I've gathered that turning is much easier when you're on the gas, and braking is much easier when you're not turning.

What kind of craziness should I expect in the rain?
