Keep in mind 370Zs are not supercars. Manufacturers are not going to bother making anything super special for our Zs. It’s not profitable for them. A standard BBK from a top brand (StopTech, AP Racing, etc.) will drop the weight more than a few pounds (see below). How ever 18" rims limits your choices. I have StopTech's BBK with 14" rotors which are supposed to fit under 18" rims. I haven't tried 18" rims on them yet but StopTech says 18" rims will fit over the 14" rotor BBK. If you’re not a StopTech fan, look out for BBKs with 14” rotors. Any thing over 14” and you run the risk of it not fitting under an 18” rim.
A couple of years ago I installed a 14” rotor StopTech BBK. I weighed everything and the results are below. Here’s a link to my install thread:

Also they have been resurfaced once.
