R33 Rotor help

[SandmanST6]

Hey guys, ok so I picked up a pair of what I thought were R33 GST-T calipers. Now after some research They are suppose to work with Z32 TT rotors. However That is not the case for me. There is about an inch of rotor that is not being used. I called around and sent some pictures to some Nissan guys around the country and they told me I had a pair of GTR calipers. This does not make sense to me because they say Sumoto on them ? I was under the impression that GT-R calipers said Brembo ? I could be wrong ( usually am ). Any way I have been waiting for a long time for some GT-R rotors and my Z32 rotors look stupid small on my car lol. I had them for about 2 months and I feel bad cuz there good rotors (brembo) just not for my calipers. Everything checks out to me when I bolted it all up. I don't know what the problem is or if I in fact have GTR calipers.

I did the google search thing and saw the comparison forum with the pictures and that is one of the reasons why I am still confused. If anybody can help me with locating some GTR rotos I would greatly appreciate it. I cant wait to much longer for the ones I ordered to come from Jap Jap land.

Try not to flame me too bad I really did do alot of reasearch. I tried Z32 rotors, 06 Maxima rotors, Z33 Nismo rotors (324mm). The Nismo rotors cleaned up the pad surface problem, However they would not bolt up ?? Only thing left to try is the GT-R rotors, unless I made a careless mistake somewhere. I will try to post some pictures later all and all any help is greatly appreciated.

If it is the Z32 with the adapter bracket, The size rotor you are looking for is 324mm by 30mm thick. It is a R33 GTR. They also have a bracket for the the Z33 brembo rotors which are the same size just less offset.

Where did you get your bracket from?

[Guilty1s]

Hold on... I read that wrong...

[Guilty1s]

The R33 GTST uses a 296x30 mm rotor and is the only sumitomo caliper to not use 280mm rotors aside from the R32 GTR which uses a 296x32 with luckly the same offset. Even though it has 2mm extra, it seems people have been making them work.

Until now, I thought all sumitomo calipers only used a 280mm rotor.

Are you saying that you've been driving around with R32 GTR calipers on Z32 rotors for TWO MONTHS? How the hell did you miss that red flag? If you truly believed that everything "checked out" when you installed the calipers with the setup you claim, then you have no right to turn wrenches without being helped/supervised by someone with reputable experience. :duh: Just because you have google, doesn't mean you know what you're doing as a mechanic.

It sounds like you bought a set of R32 GTR (non Brembo/V-spec) Sumitomo calipers. The R32 GTR V-spec and the R33 GTR came with Brembo calipers, so they are not from a R33 GTR. The stock 300zx rotors size is 280mm x 30mm, unless they are from a 1990 non turbo which uses 280mm x 26mm rotors. I am not surprised that they look small being 16mm off in diameter.

If you have R32 non-Brembo calipers, you'll need these rotors:

Project μ, one piece = SCRN001 (http://www.nengun.com/project-mu/scr) (discontinued)

Just so you know, the Z32 and the R32 GTR non-Brembo calipers use the exact same brake pads for the front calipers, so at least the pads are easy to source.

Just say "Japan" from this point forward. Not only do you sound offensive saying "Jap Jap land," but also an idiot for sure. Also, "alot" is not a word it's two. Hopefully my post prevents you from making "a lot" of mistakes in the future.

When installing this setup, you'll need to either remove the dust shields, cut the lip off, or bend them back.

Thank you all so much for your help in this issue. King ur a bit of an A$$ but your knowledge on the subject is defiantly on point so I don't care LOL! Here are my calipers of which really look like R33 GTS-T but somehow are acting like GTR calipers??? As you can see there is about an inch of the rotor not being utilized down towards the hat in the top picture ... This bugs me because they are suppose to fit the R33 GTS-T calipers, However they do not so KING can you confirm that these are in fact R32 GTR calipers ? The second picture is 06 maxima rotors just ignore the rotor part. I put it up so you can see the calipers. The only thing I can see is that the Sumoto is by the NIS and not that SAN part like the other R32 calipers in the picture. As far as the casting it looks like GTS-T"S ?? I really dont know too much about Skyline parts, just what I have to deal with so please bare with me ! Lastly as I previousely states the rotor I currently have on the car do not fit these calipers? They are Z32 TT brembo rotors so I believe they are 280mm by 30mm. Just so we are clear I had no choice I had to use the Z32 rotors to drive the car.... I was not going to wait almost half a year for the correct rotors, call it what you want but i needed wheels! As soon as I bolted it up I knew it was wrong, but my options were few and far between.

Those are R33 GTS-25t calipers. Every bit of the supporting hardware for them is the exact same as Z32, R32 (GTS-t) etc... and the calipers & JDM GTS-25t rotors are the same dimensionally as the R32 GT-R (non-V-Spec); except in a slightly different casting. I run the exact same calipers with R32 GT-R (296 x 32mm) rotors that I brought home from Japan...

They should look like this installed:

The rears are identical between R32/Z32 & R32 GT-R.

Hope this helps, or at least reiterates what has already been stated=).

[brndck]

wow either way, that much of the rotor being exposed/unused should have been a HUGE red flag. at this point its pretty common knowledge that GTR front calipers do NOT mix with z32 rotors. 30 seconds on google will confirm this.

[garagelu]

DBA sells the rotors you need. Just google it and find DBA rotors for R33 GTS. I had R33 GTS calipers and I ran into the same issue as you. Well, I knew beforehand that Z32 rotors wouldn't work though. But in the end, I found some OE Nissan R33 GTS rotors that were nearly new on zilvia. But before I found those, I almost went the route of buying DBA.

In the end, I would much rather spend the money on STI or EVO brembos. Rotors and pads are much easier to find and performance is so much better than OE Nissan calipers. My first upgrade was Q45 which was a big improvement and then went to the R33 GTS calipers which I felt were not that big of an upgrade over the Q45. Later I got STI Brembos that blew everything out of the water. And now I have project mu BBK and they are just unbelievable.

[thefro526]

I had the same exact problem with my R33's.

There's kind of a grey area of for information on these, it's easy to find that R33 GTS-T Calipers DON'T work with a Z32 Rotor, but it's hard to find what they DO work with.

The easiest/cheapest/fastest solution is to run a 97-01 Q45 Rotor up front. All of the dimensions are the same between an R33 GTS-T Rotor and a Q45 other than the width, the R33 is 30mm where the Q45 is 28mm. IIRC, I paid something like $60 for two front rotors from a local store.

Yes, It was a red flag but like I said I did not have a choice .... I knew what did not work I just did not know what did fit until now. Thank you all so much for your help so the solution is 296x 32mm R32 GT-R rotors !!! thank you

Mike where did you find one of those rotors with the hat ? I hate when mine rust looks so sloppy. I kinda want to paint them but im sure that will mess up the heat displacement or something ???

I just painted them w/high-temp Rust-Oleum before I got them turned. Not a lot of heat displacement going on in the hub region if they are installed correctly- unless you spend lots of time at the track. Much nicer than letting them get all rusty=)

As far as 296 x 32mm Skyrine rotors go, Ebay usually has them for decent prices as well.

To the OP your calipers are NOT r33 gtst calipers there r34 GT-T and look identical to r33 but the ears on the caliper that mount to the spindle are longer.

both made by sumitomo

just look at the spacing from the hub lug to the actual caliper and compare the the distance and you could see there is a difference.

you will need r34gt-t rotor not r33gtst.

you need a 310x30mm rotors not 296x30mm rotors

[Mikester]

^^The spacing was there in his second pic b/c he staged them on Maxima rotors for a better view of the caliper. They are R33 GTS-25t calipers. The 14mm difference is only 1/2", so it would only bring them 1/4" further out on a 296mm rotor- not all the way out to where they are in his pic=)

As far as the pic of my installation goes, I personally took the calipers off an R33 and the rotors off a GT-R so I know my setup is correct~ Not trying to argue, and we may very well be saying different versions of the same thing.

[thefro526]

Hey Mikester,

Did you have any issues with running the GTR rotors on your R33 Calipers when using brand new pads and rotors? I just did new pads/rotors all around on my car and ended up running 296x28mm rotors from a Y33 Q45 and I found that my pads went in a bit tight on the rotor... but I may not have set the pistons back to their fully retracted length...

Then again, I guess if the additional 2mm of thickness on the GR rotor caused a problem, it'd just be a matter of taking about 1mm of brake material off of each pad with a grinder/file/etc.

I had no issues whatsoever with them- they are dimensionally identical. you probably didn't compress the pistons far enough. The extra couple mm is not a factor.

Here is a shot of the rotor going into the channel. The fitment is spot-on with only a couple mm per side to spare & plenty of room for new pads to clear when the pistons are fully compressed:

http://farm9.staticflickr.com/8338/8255704069_f6b68affa2_b_d.jpg

Even tho you can't really see them, The pads are brand new HPS's with less than 40mi on them. The rotors were used when I got them and I had them turned before rebuilding everything and putting it all together. But the way it went together, I am certain that there would be no clearance issues with brand new 32mm rotors; let alone 30's.

Based on your uploaded pictures, I assume they are either R33 GTS-25T or R34 GTT calipers. I wouldn't be able to confirm what you have exactly unless you took pictures of the mounts. As you can see the calipers are identical except for the length of their mounts.

R33

R34

http://i232.photobucket.com/albums/ee277/289hilux/rotors/Nissan%20Calipers/R34GTTcaliper.jpg

If I had to guess though, I would say they are R33 calipers for reasons already stated in above posts. Also, I assume the calipers bolted right up. If that's true they are for sure R33 calipers because all R34 calipers use a M14 thread, whereas the S13/S14/Z32/R32/R33 use a M12 thread.

Although others have mentioned different rotor applications that work/partially work, I highly recommend buying the proper sized rotors. The proper size rotors for the R33 GTS-25T calipers is 296mm x 30mm. Now that DBA rotors are more readily available to ship to the United States, there is no reason why you can't buy the proper sizes. In the past, people with R33 GTS calipers either bought R32 rotors and had them machined or filed/sanded down the pads. Both of these things are no longer required, nor do I recommend. Another reason I recommend getting the proper rotors is because it cuts down on future confusion for you or the next owner if you choose to sell your car.

Here is the DBA part numbers for the R33 rotors; DBA4963S (http://www.amazon.com/DBA4963S-T-Slot-Uni-Directional-Slotted-Brake/dp/B007B8VC8S/ref=sr_1_1?ie=UTF8&qid=1355505688&sr=8-1&keywords=DBA+4963S). Since the rotor veins are not directional, you can purchase two from amazon for $355 shipped.

The DBA 4000 series rotors I used were garbage. Copy and paste from a previous post...

Call your nissan dealer (or favorite online dealer) and tell them to order you up one of each 40206-05U10 and 40206-05U11 (They are directional!) from Nissan Motorsports (you can also order from Motorsports directly) for blank 296x32 rotors (they fit in my R33 GTS-T calipers just fine, with brand new pads) they are about $100 a piece though. If you want crossdrilled, order 40206-05U02 and 40206-05U03, those are almost $140. Nismo calls the blanks R32 Skyline GT, while the crossdrilled are GT-R.

The 32mm wide rotors fit fine in my GTS-T calipers, no grinding/trimming or anything, with brand new pads/rotors.

Just don't waste your money on DBA 4000's. Daily Driving with some mountains tossed in, about a year of use...not sticking calipers either, they were rebuilt prior to these rotors being installed.
