concept z performance & z1 (both states based) both sell the akebono kits to suit z32 (& thus r32). Sub $2k plus post for the full kits, then can option 2 pc rotors, etc. Just the fronts is about $1100 I think, plus post.
Another recent z32 option uses z34 rotors with the brembo calipers from a 300c str8. Calipers can be had for reasonable money from ebay US, dogbones are done by a guy on 300zxclub.com
