hi guys, Can someone please tell me which r32 calipers were made from aluminium ? i know they came in GTS/GTS-T/GTS-4/GT-R was there a certain year of which they were then manufactured in cast iron. For example, the 300zx z32's came with aluminium only between 1990-92, then after that regardless of NA or TT model they all used cast iron items. can any one please tell me which year/models came with aluminium calipers, (only after information on 4-piston calipers and the r32 model) thanks for your time.

still have individual throttle bodies. ???
