bah.. i have an SH.. and i LOVE it.. drove my friends non-sh 98 lude, and it didnt grab the road as well.
you can disable ATTS by removing a fuse. simple as that.
i can handle curves at high speeds pretty damn well.. i have sway bars front and back, coilovers and springs...
if you have the chance, drive a sh, and non-sh.. and take the same curve with it. then decide.
i havent had any problems with mods or anything. the oil is a little harder to change though

but oh well. it's worth it.
