S30TRBO Posted February 12, 2009 Share Posted February 12, 2009 Maxima bracket/280zx caliper swap Description: Using '85-'88 maxima rear caliper brackets, 280zx rear calipers and rotors to convert rear to disk. Source of parts would be mainly junkyard, and you would have to either remove the stub axle (don't do it unless you absolutely have to) or cut out the drum backing plates to install. The downside is sourcing your own caliper brackets at the JY, and then REMOVING them. You will likely need cordless power tools to do so. Motorsport auto sells their bracket swap kit, which is CNC'd maxima brackets here. It is $320, and does not include rotors, pads, and calipers. You have to source your own. from: http://forums.hybridz.org/showthread.php?t=104735 Quote Link to comment Share on other sites More sharing options...
autospot Posted February 13, 2009 Author Share Posted February 13, 2009 Yes but my 1981 280zxt rear calipersa dont bolt up to the maxima brackets . The bracket bolt pattern is about 1 inch wider. Also what rotor [stock 280zx ] Are the 1981 zxt calipers different than the 82,83 zxt? If someone can post what caliper what rotor and what year these parts need to come off of that would be a big help thanks Greg Quote Link to comment Share on other sites More sharing options...
Trevor Posted February 13, 2009 Share Posted February 13, 2009 Are the 1981 zxt calipers different than the 82,83 zxt? Yes, they are. '79-'81 are "sheet metal" and use a deeper rotor, '82-'83 are cast iron and use a shallower rotor. Quote Link to comment Share on other sites More sharing options...
