90-92.5 aluminum
92.5-96 iron
iron is heavier so more unsprung weight, but they are also stronger and more durable, prolly the most reliable in the long run.
aluminum will save you a few pounds and is the type i am personally going for. i doubt there is much real world difference tho.
can i ask where u are purchasing them? im looking for 240 back calipers and 300zx front calipers at good prices...
only place i have looked so far is
http://www.autopartsgo.com, they have them for around $140-160 each.
ALSO::::: anyone know if the 300zx brakes will fit behind stock 1993 240sx steelies? how about the Rage Breaker wheels?
