It's actually pretty awesome. It helps with understeer when you are at speed, and I'm able to parallel park the thing with ease. It feels a little strange at first, but you get used to it real quick. It's funny watching people's faces when they ride with me for the first time because it feels like the rear end is broken...lol.
My first 3rd gen (89 S) didn't have 4ws. I found an 88 4ws in one of my local junkyards, pulled all the required parts, and installed the system onto that car. I sold it to a friend and he loves it too. Now there's no going back to 2ws for me, at least in a 3rd gen prelude.
