Brake Upgrade Thread

I wanted to start a Brake upgrade thread.

I know most of you have probably done the z32 front swap, but now there are more options since new kits have come about such as the 350Z track rotor swap and new light about the rear z32 calipers fitting, and now even swapping the z32 master cylinder

here are some links for that said equipment

300gt VR-4 Rotor adaptor kit, 12.5" rotor

350Z Track edition adaptors for the z32 that could theoretically be used on the Z31
http://www.yugobernie.com/brake_adapter.html

Apparently this will happen to your pads due to the z32 caliper designed for a smaller diamter rotor…see image below

After seeing how the kit mounts to the z32 caliper bracket, I would suppose we need to measure the thickness of the z31 caliper bracket for compatability

Here is the thread from z31.com about the rear calipers fitting

Here is a write up about the z32 master to a 240sx, I think it is easier to swap to the z31 than it is a a 240sx, rick88ss has said he has done it already

And here is the z32 caliper write up

oh, and here is a link to ArizonaZcar for the line-lock for a parking brake if you do decide to use the z32 rear caliper or equivilent without the cable pull parking brake, Arizona Z Car also make a complete upgrade kit which could theoretically could be made to fit the Z31

And after doing some research, here is the push button Line lock for sale separately
http://www.spidertrax.com/s.nl/sc.2/…it.A/id.620/.f ~$35.00

AP Racing makes 3 kits for the Z32 which theoretically could be made to fit the Z31
http://www.brake-pros.com/specs/AP1145info.pdf 14.5" rotor= ~$2800
http://www.brake-pros.com/specs/AP1100info.pdf 13.5" rotor = ~$2800
http://www.brake-pros.com/specs/30-1100info.pdf 13" rotor = ~$1700

Rear Z32 caliper upgrade

well I slapped them on today…the centerline of the caliper and rotor match perfectly.



The only problem is that the rotor is a tad too small, you can just barely make this out in this shot(i know crappy cameraphone)





the dark orange band is where the stock pad stops, this picture shows how much higher the z32 pad rides above that line where the screwdriver is pointing

The difference on the bottom of the pad(closer to center of rotor) is that it rides about 3mm higher than the stock pad. and at the top of the rotor(farthest from the center) is about 2.5mm above the rotor.

that means something like this might happen



I say go for it as the weight savings is massive…only downside to this mod is that you loose your mechanical parking brake

Jason, I don't have the time to do a full write up, but maybe we could do a jont effort to preserve an archive of this info for ourselves on one page incase any of these links go down. I will be trying most of this stuff on my 89, I might not go with the Track rotors just because I think it's overkill, I personally don't think they are necessary unless you are going all out track car, or you're into the bling

I'll be adding info once I get my brakes(just got them off ebay for $190 front and rear z32 calipers) trying to fit the rears to the vented rear rotors and whatnot

Please add your input to make this a great Brake Upgrade Thread!
