I'll get on to my parts man and see if they are availible new? If so Ide emagine they cost to much from nissan, and not likely to finde some at wrecker. might still wind up going withthe RX7 ones??

What about the Nismo MK-63 4-pot aluminum calipers? They are designed for 280Z, will they fit 280ZX?

B310 with A14/A15 used 88.9 mm (3.5") caliper bolt spacing.

Bummer.

very much doubt that the z32 rears would be enough, they use a tiny pad and the pistons are midgets also....just coz they are twin piston calipers doesnt really mean much as they are doing the same job as a single piston caliper of the same piston size would do

infact id go as far as saying that a stock coupe caliper would be just as good apart from the solid disc VS vented disc

Im going to hav a crack at useing Z32 rear calipers on the front of my 1200. should be more than enough and nige and light.

Nick, as mentioned Wilwoods will be the ticket. They made a bolt on for ZX carriers. One thing to keep in mind for 13" rims; the top of the caliper needs something like 8-10MM milled off to fit inside a 13" wheel and will still need a wheel spacer. I too have the 2 ton ZX Calipers on my car and will eventually use Wilwoods. We used Wilwood calipers on the sports racer and they work very well. Also for a mildy tuned engine like mine the ZX brakes are overkill but they came with the racing suspension I bought 15 years ago, so I've used them ever since.

As far as I know and I have been at it for a while now, there isn't an easy answer to that one Nick. The commodore calipers have a 3" spacing, but apart from that they are quite compact (they do fit in 13s I have done it) and quite lightweight (half al. alloy). In the 3.5" spacing, IMO wilwoods are about your best option. You could engineer some OEM four pots from Nissan/Mitsi/Mazda/Subaru/whatever but to get them to fit in 13s is a big ask. Not impossible though. But tricky. Early Z has a cast iron two pot caliper not particularly light and whether it's any better or worse than the 280ZX caliper i don't know. You can still get sel kits and pistons for 280ZX calipers I overhauled the ones on my old rally car last year.

yeah all the Z/ZX guy's seam to go big.

There was a kit selling on ebay for wilwood calipers but I can't find the link.. maybe adapting something yourself would be the best bet, try find some cheap wilwoods from the US for 10"x19mm rotors and go from there.

I am using the standard heavy zx calipers for now, I just got some lighter 13's instead.

You guys tried browsing the zed forums for some ideas or are they the big setups?
