which caliper is this???

[nlzmo400r]

hey guys, these calipers are from a 91 n/a 300zx 5spd. I dunno if they are the 26mm or 3omm, i know they are aluminum, but how can i tell which they are? i really need to know because if they are 26s im picking them up and going to rebuild them, but if they're 3o's, they wont fit behind my stock rims. Help please, thanks in advance- Rob

go to zilvia.net and check in the links section. Then scroll all the way down in till you see the section about the 300zx brake calipers its very helpful

well judging by this site http://www.princeton.edu/~asad/zbrakes/ , the brakes are 30mm aluminum,ive found the same results on numerous sites. So i guess im going to autozone and trading them in (plus 1oo bucks) for some rebiult 26mm calipers
