zguy95135 Posted September 7, 2003 Share Posted September 7, 2003 my father bought a 81 1/2 turbo 280zx. i know that it is possible to put the rear disc brakes onto a first gen Z but what about the fronts w/calipers? since they are vented would they be too big for the spindle?

blueovalz Posted September 7, 2003 Share Posted September 7, 2003 You could put the entire front brake assembly onto the Z, but it would require more work than simply using the 280ZX front calipers with the '84 300ZX rotors (these rotors are larger than the 280ZX rotors). Reason: the 300ZX rotor is large enough that you can remove about 1/4" off the diameter of the rotor (any brake shop can do this) and still bolt the 280ZX caliper onto the original Z caliper location. Using the smaller 280ZX rotors without modifications to the radial location of the caliper will result in only a portion of the ZX caliper brake pad making contact with the rotor face due to the smaller rotor diameter. All of this information is based on having the early (240) hubs which have a thinner flange, which allows minor work to fit the caliper over the rotor correctly (thin spacers or washers). The thicker 280Z hubs space the rotor too far inboard for an easy fit with the caliper mounted to the Z caliper mounting bosses. In the end, there are much easier and better ways to improve the Z brakes than the use of the 280ZX rotors. Quote Link to comment Share on other sites More sharing options...
