For your 6thgen’s you need either the 30MM Aluminum or 30MM Iron Z32 Calipers for proper fitment. They are 4-Piston calipers. You will also need the brackets for them. You can usually find the calipers on eBay for good pricing. I would say approx. $200-$250 for a good set of rebuilt calipers.

Weight Difference:
Stock: Approx. 15 LBS
300ZX: Approx. 6 LBS

The brackets used to be made by a member Matt Blehm. They are no longer available. However, you can find them used on the forums or Facebook groups from time to time.

The following is a comparison of some different Z32 300ZX brake calipers.

The “26mm Aluminum” calipers were used ONLY on 1990 non-turbos. They used a 280mm x 26mm rotor.

The “30mm Aluminum” calipers were used on 1990 Twin-turbos and ALL 1991-1992.5 300ZX’s (both turbo and non-turbo alike). They used a 280mm x 30mm rotor.

The “30mm Iron” calipers were used on ALL 1992.5-1996 300ZX’s (both turbo and non-turbo alike). They also used the 280mm x 30mm rotor.

Of course, the easiest way to tell aluminum from iron is to use a magnet, but I hope this helps some people trying to figure out what they’ve got/are getting if buying with just a picture for info.
