Guest Battle Pope Posted April 5, 2005 Share Posted April 5, 2005 I did a search but didn't find anything super-specific... has anyone done this? I have a friend who's parting out an '87 Supra, and I could probably pick up the front running gear for 50 bucks or so. I was just wondering if anyone has done this setup and what it would take to get it working. This is for fronts only by the way. Quote Link to comment Share on other sites More sharing options...

blueovalz Posted April 7, 2005 Share Posted April 7, 2005 Jon, thanks for takin' care of business while I was out of town! When I did the 300ZX rotor/280ZX caliper upgrade, it was better than the OEM brakes in performance, but not yet what I was comfortable with. Then when I upgraded again to the Supra brakes, the improvement was another full step upward. So much so that I've decided to call it quits on any further upgrades (even though I've got a Cobra rotor bolted onto the Z hub) until I see any need for more heat dissipation.

Guest Battle Pope Posted April 7, 2005 Share Posted April 7, 2005 Do you have a write-up on this? A parts list? Maybe a little how-to? Any info would rock, I can pick up some mk3 Supra calipers for next to nothing. Quote Link to comment Share on other sites More sharing options...
blueovalz Posted April 8, 2005 Share Posted April 8, 2005 My Fototime photos are the only documentation I've done. With that said, I believe the rotors are the same width (thickness) as the 300ZX (but you should verify this first) which would mean, that with the appropriately fabricated bracket, you may be able to us the 280ZX front calipers (if you couldn't locate good Supra calipers). The pad area, and piston diameter are all the same between the two calipers. I had a machine shop opened the center hub hole, and drilled 4 new mounting holes on the new rotors for $30/rotor. The only concern about doing this is that the rotor needs to be a fairly snug fit (but not too snug) over the hub. I had mine machined so that the bolts would draw the rotor down onto the hub. I believe it is 81mm in diameter (3.1907 as the machinist measured). This kept it true with no run-out. The Supra caliper's mounting bracket also spaces the caliper further out from the mounting bolts (as seen from the photograph) which may benefit those attempting to fabricate an adapter plate) than the ZX caliper does, and this increased offset looks to be by the same amount as the increased diameter of the rotor over the ZX rotor.
