Personally, I haven't try drifting in my V35 coupe. But there are videos on Youtube that show V35/G35 coupes driftings, burnouts, etc. so should be fine with abit of mods.
If it's for daily as well, V35 coupe is a go.
If it's only for track, I think 350Z is better as it has shorter base which can help in drifting and has more aftermarket mods background.
Good luck in your choice.
