I bought it because I didn't want to have an insufficient cooler for when I went to the track, the HD just wasn't big enough.
Before the cooler I saw the temp up to 250ish when I really got on it. Most of the time a little bit of spirited driving had me sitting between 220-240+ all day and that really pissed me off.
Get a cooler, the Z needs one, the size of the cooler will depend on your intended use of the car. I'm sure eventually either GTM or a fellow member can construct a shroud for you.
BTW: what temperature is considered overcooling?

Below 160* or 170* is way too cold to be romping on it hard -- insufficient lubrication, although it's probably less of an issue with a good synthetic, which may have a wider heat range, hot and cold. I'd say 180* is the bare minimum and 200* is probably ideal.
Anything north of 250* for extended periods is iffy, but a good synthetic will still provide protection, for short bursts anyway, well over that.
Looks like a lot of folks on here like redline -- I'll probably go for that.
