Is it twitchy on the freeway? I'm debating upgrading UCA's when I do a 2 in. Dobinson lift.The road manners are definitely an improvement over the non-A Wildpeaks. Just a ride in my friend's 4Runner with the same lift could tell me that. They're definitely solid on-road and I haven't had an issue with them in the sand. However I have yet to take this thing to the mountains due to my extremely limited free time this summer.
As far as fitting a spare, I haven't tried. If it does fit it'll be tight.
