Guest Anonymous Posted July 2, 2001 Share Posted July 2, 2001 Does anyone know if this will work? What are the Mods? Also, With the rear disc conversion (83 ZX to Z), will the stock Proportioning valve work? Thanks for the input. Chris 77Z Quote Link to comment Share on other sites More sharing options...
blueovalz Posted July 2, 2001 Share Posted July 2, 2001 Chris, If I remember correctly, the 280ZX rotors where too small not only for a simply bolt-on operation, but because they are simply smaller than the OEM Z rotors. The 300ZX rotors are a different story. The 4 lug 300ZX rotors will fit fine using the 280ZX calipers and 240Z hubs (the hubs with the half moon shaped cutouts on the circumference of the hub between the wheel studs, and with the 17mm thick flange). Later model hubs have flanges too thick to make this a simple swap because they set the rotor too far back to make the attachment of the caliper easy. If you take the rotors to a brake shop and have them remove about 1/8" off the circumference (radius, not diameter), then the calipers should bolt up nicely with only a small thin shim (I used a thick 12mm washer as the shim), and this is a close estimate so don't quote me on that dimension).
