B00STDZ

Interesting... I've pretty much thrown this idea out as it makes more sense to just keep with the stock position.

Top three are Cal Poly's z project.

I say fabricate a very thick(to close gap between stock mount and caliper mounting ears using a "slip-over" rotor), strong, and light bracket and mount it as this one is mounted..

Here is what others have done...

Recieved a Pm questioning about the caliper mount, rotors, and 5 lug hubs. Thought I would share the information on here... Yes it does place the mounting ears farther away from the stock mount. Big brake kits for the 300zx could be used as a model of what we are trying to accomplish such as this kit. http://www.conceptzperformance.com/Cart/description.php?II=881&Car_Type=300&UID=2011042207493998.19.146.227 Why this mount wouldnt work with an s30 is the bolts are spaced 90mm apart and on a z32 they are 100mm. But a bracket of similar design needs to be made using the z32 calipers to be able to mount on a z33 track rotor(has to be the TRACK edition 350z rotor as that is the biggest one to be offered on a 350z) Just when you buy aftermarket make sure you check to see if it is for a track edition 350z. As far as rotors, 350z brakes have a HUGE aftermarket selection for rotors. Ive seen rotors as cheap as $88shipped for a pair to $1000 PER rotor(The most expensive rotors being DBA 2 piece 5000's, ENDLESS brake rotors, and Project MU brake rotors. Personally I like the ENDLESS brake rotors the best, but are waaay too expensive for my budget. But in the future if I ever want those rotors if I have the bracket already all I have to do is swap the rotor out. On the 5 lug hubs, You dont need MM 5 lug front hubs! Z31 88-89 T hubs are just as good. Now on the rear you will have to order from MM to convert to 5 lug. I do not have the round z31 hubs but am trying to find a set. Not only are they more desirable for us s30 owners but I have figured out through z31performance.com that these hubs are necessary to put a big brake kit on a 84-87 z31. That or you have to get the pentagon hubs machined round which seems to me as to much trouble so hopefully I will run into a set of round hubs. As far as the parking brake goes, check out AZC's seperate ebrake caliper. This is not a new concept as Lamborghini's and other exotic cars use 2 calipers in the rear; one parking, one braking. For the rear rotors I posted in that thread the rotors I THINK should work with the z32 calipers. Diameter and thickness checks out, so we should be good. Back to brake rotors, the ones I am looking at for the front and rear are DBA 4000's. They run about $200 per rotor, middle of the row, slotted, offer decent performance. But like I said earlier you can go crazy on the rotors if you want and spend a whole lot.

Iron late model caliper 93-96 300zx z32

Bore the disc rotor? Are you referring to the hat? With a z31 round hub no boring is required. And to add to the information in this thread to anyone searching Z32 calipers, 240sx calipers AND Skyline GTR calipers ALL bolt up the same! Another question, I take it the GTR rotor is 4 lug? Do you know how big the disc rotor is?

Never seen a write up on the swap before. The combinations I got from the first post is information that I have pieced together from different websites/threads/posts/research.

I guess im on my own with this one. Uncharted territory! Well I'll post up how it works out.

Alright Here is what I have gathered about the swap. This is what I plan on using, converting to 5 lug in the process. Front -Z31 5 lug round hubs (88-89 turbo 300zx)[These are the hubs that allow you to slip a rotor overtop of the hub] -Z32 Front 4 Piston Caliper -Z33 02-08 Track Edition front vented Brake Rotor (Rotor size = 12.75" x 1.18") -Custom fabricated bracket to fit the z32 caliper to the z33 rotor Rear -Either prepped Modern Motorsports 280z 5 lug stub axle hubs or Modern Motorsports's machined 5 lug stub axle hubs -Modern Motorsports Rear disk conversion Bracket -Z32 Rear 2 Piston Caliper[should bolt up same as 89-94 240sx caliper as they carry the same bolt pattern; but they clamp a different thickness rotor] -96-05 Acura TL front vented brake rotor (Rotor size = 11.4" x 1.1")[should be a perfect fit thickness wise for the z32 caliper to clamp and diameter wise to work with the MM conversion bracket] -ArizonaZcar parking brake caliper http://www.arizonazcar.com/parkingcaliper.html Looking at using DBA brand rotors or Powerslot. How does this list look? If all my calculations are correct it should workout/fit perfectly.

This is saved for my own referance. The 5-lug swap is quite easy, the most difficult part will be getting the caliper-disk spacing correct. I have done this swap on several 510's and it works really well. Get the front hubs and rotors off an 84-89 300ZX Turbo, or an 86-89 non-turbo 300ZX. Remove the hubs and rotors off of your 280ZX struts and slide the 300ZX hub onto the spindle. You will note that the spacing for the rotor does not match the caliper. You will need to make or fabricate a spacer to match the difference between the rotor and where the caliper mounts to the strut. Another way to do this is to seperate the disk from the rotor and make a spacer that fits between the hub and rotor. This is also an excellent opportunity to upgrade to a better front brake caliper. The 300ZX disks are 11" diameter and vented-- even bigger than your 280ZX disks. One swap that I saw that worked really well was the use of Toyota four-piston truck calipers on the 300ZX disks. The Toyota calipers are very common and easy to find. They are however, very heavy as they are made from iron. Another brake caliper to use is the one off of the 86+ Mazda Turbo II's. This is an all-aluminum, four piston caliper, and can be found quite easily. The RX-7 caliper is very light, and there are plenty of performance pads to be found for them. This is the setup that I am using on my 510. You will have to build a spacer to use these calipers (but you have to do that anyway) and you will need to match the RX-7's caliper bolt pattern (easy to do). ** note from Ross: these pads are ~4x3", a huge pad by any standards!** The rear disks are easy to convert to five-lug. I am using 280ZX rear trailing arms so I have direct experience with this part of the project. First remove the four-lug disk, caliper, and stub axle from the control arm. You will need a large impact wrench to remove the stub axle, they have a single, very large nut that requires an impact to remove it. Slide the stub axle out of the control arm and use a press to remove three of the four studs. Since the four lug pattern is 4x4.5, and the 5-lug pattern is 5x4.5, one of the studs is in the correct place. I had a spare 5-lug disk that I used as my pattern. Slide the disk over the remaining stud and center the disk onto the stub axle. Once you are sure that the disk is centered, mark the other four holes. Use a drill press to drill the holes just barely larger than the new studs that you are going to install. You want the studs to just fit through the hole. Using the press again, press the other four studs splined ends into the stub axle. One of the studs will be close to the edge of the stub axle because of the 5-lug pattern. We determined there is enough material to support it, but if you are concerned you can easily add more material. You can redrill your rear disks for a 5-lug pattern, which would be nice because then your rear caliper would work, or use the 300ZX turbo rear disks and calipers, but they are a larger diameter so you will need to make a new caliper mount.

Interesting... Your probably right. I see what your saying, keep the caliper position matching with whatever suspension/chassis you are using.

I heard it was ideal for cooling. But after further reading I have done just now, they say it really doesnt matter all that much. They talked about the calipers mounted center most being better for weight transfer? So idk. Also they commented that you dont want the brakes too cool as they wont work properly? Maybe it would be better to just keep the stock position. Anyone have any input? I just thought that because the z32's caliper was positioned that way and it being newer if you were to switch the calipers that you should retain the stock z32 caliper position.

Well I think I am going to attempt swapping the assemblies this coming week.

If thats for a z32 front caliper I need that too. But I know no one makes that bracket that I know of so I was going to have it custom fabricated. Also on switching the s30 front brakes to z32, check out this thread I posted. http://forums.hybridz.org/index.php/topic/99573-front-caliper-position/page__pid__933738#entry933738

Haha I wish man. Thats why I posted a WTB thread for the brackets. I already have z32 rear calipers...

There is no documentation of using a z32 rear caliper on an s30. But it makes sense that it would work as 89-94 240sx guys can switch to z32 calipers on the rear without modding the mount at all meaning the bolt pattern is the same as well as the distances.

Either works from my research. Also the bracket doesnt mount right on the hub, but rather a few inches behind the hub on a bracket used to mount the drum assembly. So the hub can be 4 or 5 lug. 4 lug you use a 300zx 1984-85 NA rotor. 5 lug you use a 1984-85 T rotor.

Not really. I was asking if the lower assemblies can be switched L to R R to L allowing the z32 caliper to mount in the same stock position as it is mounted on a 300zx

I guess no one has ever thought about doing this? Makes sense to me that it would work and should look better and operate better in the z32 position...

Yeah 300zx rear brakes are more ideal. They have the same mounting/bolt pattern as the 89-94 240sx. So I am planning on buying MM adapters and putting z32 rear calipers on them. Should bolt up perfect. Ebrake might be tricky. As z32 uses a drum ebrake that sits inside the disc. But I say z32 rear brakes are better than mustang rear brakes and 240sx rear brakes. z32 rear brakes are 2 piston aluminum calipers whereas mustang/240sx rear brakes are 1 piston.

Dont think they work with 89-94 240sx/90-96 300zx calipers though...

Well insince I'm having difficulties getting in touch with ross as usual, I was wondering if anyone has a set they would like to get rid of? I have paypal ready...

Haha wow. Could this really be a 260z? hmmm... http://cgi.ebay.com/ebaymotors/Datsun-Z-Series_W0QQitemZ120708888759QQcategoryZ6187QQcmdZViewItem

What is circled in green is the "assembly" I am referring to. The caliper mount is welded to that. I say you take the right, put it on the left side and take the left and put it on the right side. Putting them on opposite sides would thus switch the position of the caliper into the position it is on a z32...
