Brackets for Z32 brakes on a S30

Recommended Posts

Got mine today along with a bunch of other Z parts. Was hoping to post some installed pictures for everyone but either I didn't see the part about the center bore of the rotor or I selectively forgot about it. Therefore, my rotors won't fit over the Z hub. Oops.

 

Everything else looks good. Hopefully I can get back in touch with my machine guy and get them knocked out.

 

Thanks Arif!

The set up will be identical to the brake set up here:http://forums.hybridz.org/topic/105586-z32-caliper-conversion-kit-front-only/?hl=brakes&do=findComment&comment=987858

 

It uses the Honda Odyssey rotors which does require redrilling for a four lug set up along with enlarging the center hole to 81mm.

It must of gotten buried in the posts but the center hole needs to be enlarged. I used my old ring adapter from my Toyota 4x4 calipers as a template. 

 

Also you have to install the calipers to the brackets BEFORE you mount them to the car. There isn't enough room to install the brakes with the adapters on the car.

I got mine last night too. I was hoping to post installed pics, but decided to paint the rotor centers to prevent rust where it was cut and redrilled. Parts look real nice.

Glad you guys like the way they turned out. The machinist didn't get a chance to polish them when I showed up. I figured you all would rather have the parts a day sooner rather than waiting on polishing.

 

I've got 3 adapters left and yes I can ship overseas as well. The price is the same, $185 for the adapters, bolts, paypal and shipping in the CONUS. If you're overseas send me a PM for a shipping quote. Thanks guys.

It's been brought to my attention that the 240z hubs are a little different from the 280z hubs which are on my car. I went back and looked at the DIY facebook page and sure enough you either have to swap out the 240z hubs for a set of 280z or utilize a washer. Here's the portion of the write up addressing it:

 

The final piece of the puzzle (if you are a 240Z owner and you purchased the same adaptor as me) is a set of 260Z front hubs. This is because the original setup was not performed on a 240z, and the hat height of a 240 differs by about 3mm. This causes the caliper to not centre over the disk once it’s bolted on. You can offset this with a small washer/spacer, but I thought best to just get the hubs.

 

JoeK brought it to my attention and he's going to see what needs to be done to get everything lined up. If anyone else that has a 240z and has installed them please chime in so I can see what I can do on my end. Thanks

I just got mine a few days ago and I'm very impressed with the part. Great job. Have not, and will not be fitting on car for some time but I am waiting to see install on a 240z how many shins I will have to use.

Thanks Gord I'm glad you like them.

I've been pming Joek back and forth. So far it looks like the 240z hubs require a longer bolt (45mm) and two washers. I'm sure he'll chime in when it's sorted out. Once we know for sure what's needed I will send out the bolts and washers to everyone that needs it.

Yes, I have found that the adapter brackets were designed to be used with 260/280Z hubs. Not a big deal, but it did turn out be a little more than just washers between the caliper and adapter bracket. I had the clearance the caliper a little, but being aluminum, it was pretty easy. But here they are installed. Place a single washer between the caliper and bracket. I used 12x1.25x45mm bolts, with a lock washer between the bolt head and the adapter, to bolt the adapter bracket to the caliper. I found that adding a lock washer behind the 12x1.25x35mm bolt that came with the kit makes it the perfect length to mount the caliper bracket to the spindle ears.

 

See the pictures and let me know if you have any questions. The last 2 pictures show what needs to be clearance, and the two before them show it clearanced. It's not much, but it rubs on the spindle ear.

When you look on the Japan auction sites with this "type" of adapter there is two different prices. I never understood why. I just looked them up, and there is something written that says the reason for the difference. The pictures on the two ads one uses the 240z hub and one uses the 260/280 hub. All the other pictures are the same? It states odyssey rotors for the 260/280 hubs, however when I put everything into google translate it states for the smaller hub 240z a r33 gtst type m rotor is used. This rotor is still 296 mm and 30mm wide however I'm guessing that the hat height is different. Which I'm assuming makes up for the difference in thickness of the hubs. I'm in Canada so getting these rotors is fairly easy, I might try eventually to get a worn out rotor off someone for free pay to get it machined and give it a try. But just looking at this it looks like it could work, maybe........

If you could just get the hat height of the R33 rotor, it could be compared the odyssey rotor and you'd know the difference. I could tell you hub thickness of the 240z hub, someone else coud measure the 260/280z hub, and bingo.

Well, this is interesting.

 

I just got my rotors back from my machinist again and he opened up the center bore as required.

 

When I flipped the adapters and used a washer as JoeK did my pads were offset with a large gap on the outboard pad.

I flipped the adapter back and removed the washer and then I had a large gap on the inboard pad.

So I kept the adapter facing the same way and added the washer back. Ended up about as centered as it's going to get. Eyeballing the pads it looks slightly off but if you judge the center seam of the caliper against the center of the rotor it is right on.

My calipers may be off of a different year Z, so that might make the difference here.

 

Just need to make a new hardline and we're good to go! Fills out the 15" wheels nicely, don't think 14" wheels would clear the caliper. There is just enough room to use sticky weights on the wheels without them hitting the caliper.
