Only times I've seen temps higher than 220 were during the summer here in Texas when temps were over 100 and that's with just normal driving. I don't think I've actually hit 260 but definitely around 240 driving from Dallas to Houston.
I daily drive my Z and essential mods I think are Tints, Valentine 1 or some sort of radar detector, navigation if you don't have it already and some sound deadening. Exhaust would be up there too but you may not like it if it's too loud.
