I am not sure that I understand what the fuss is all about with changing rotor diameters and the effect that has on the pad shape. Sure the inside and outside radius of the pad will be ever so slightly different to the inside and outside radius of the rotor. But is it such a big deal?

The first picture Roy posted shows that he could have used a 2 mm larger diameter rotor with those pads. Noting that there is not really much of a problem with the different radii.

If you are currently using a 280 mm rotor (R32GTST) then you could be using pads shaped for a 280 mm rotor or a 296 mm rotor. There are far more compounds available for R32GTR’s, hence 296 mm rotor. So if you buy GTR pads for your GTST (with its new 324 mm rotors) you are only talking about a 28 mm increase in diameter from where those pads are designed for.

Hardly a big deal, since the same pads work OK on 280 mm versus 296 mm ie; a 16 mm difference.

The next step up would be to use the R34GTT pad which, being designed for a 310 mm rotor, would just about fit perfectly on a 324 mm rotor. I haven’t actual tried R34GTT pads in an R32 (GTST or GTR) calliper. But that could be the answer, to what is not really a big deal anyway.

:D Cheers :D

I spoke to Race Brakes Sydney and they will do the 5000series 2piece for $450ea or 4000series 1 piece for $245 ea better for a group buy.They told me to have a look at the db1170 and db1199 bendix pad and you will see the pad material sits lower on one pad than the other this may or may not be the secret of pad overhang.They are also happy to organise group buys if we can get anything together let them know.They do AP kits and also have the caliper kits for the nissan 4pot calipers and 1 /16 brake master cyl kits as well.

Thankyou very much for the explanation, much appreciated and very logical!

I will get a price for the DBA 5928-1 tomorrow and see where it sits.

Cheers,

Caz.. :action-smiley-069:

Hey Caz,

Did you manage to get a price on this??

Thanks

Dane

Any word on the 33GTS25t adapters for the 324mm disc? Also would these adapters mean that you cant use your standard spare tyre on the front of the car?

cheers

My calliper brackets arrived the other day, they look good

1. solid construction

2. nicely machined out of the appropriate alloy

3. steel hellicoiled threads

4. High tensile allen bolts and spring washers

Picture follows;

I am going to use them with the DBA 5000 series rotors, which I picked up at oran Park last weekend.

Hopefully I will get some time tomorrow to fit them onto the R32GTST, take some pictures and post them up.

:miner: cheers :rofl:

Has anyone been incontact with caz, i have pm'd him and got no response. I am keen for a set as i have some 324mm rotors here. just a question though, will they fit under the standard 16" wheels on a 32?

not a chance

Do you have R32GTST or R32GTR?

Because the current kit won't fit R32GTST's, Caz is currently working on a new kit for them.

:laugh: cheers :mad:

:P cheers :woot:

do they work on GTRs though? that's a bit of a shame :( I thought they had been tested/developed for GTST too?

:( cheers :no:

Did you get the last set SK? Any idea on how long untill there is more as per your pics for the r32 gtst?

Cheers :P

hoping this bumps gets this thread some attention....

i want to fit 324mm GTR rotors to my R33Gtst with standard callipers and need the brackets (well depending on how much they are - if they're not too expensive, for sure, if they are, well i don't think the gains will be worth it - but anywaaaaay!)

so does anyone know where you can get this brackets from and approx. cost??

Cheers

I used the Unique Autosports calliper extenders and brake scoops on the R33GTST for the recent SAU day at Wakefield with DBA 324 mm 5000 series rotors, Nismo braided hoses, Castrol Response Super Dot 4 Brake fluid and Bendix Ultimate pads. No problems locking the brakes on demand using Yokohama R tyres even after 2 consecutive 15 minutes sessions. No fade, no shudder, no problems on the day or since.

I will post up some pictures of the installation process and the finished result when I get a chance.

:laugh: cheers :domokun:

yep UAS make and sell them. sure they may not be dirt cheap but they use good materials, and have done all the testing and design work for you. www.nismo.com.au

    • So the original radiator is leaking now. Looking at getting a fully aluminium one next. Am I correct in saying that the Series 2 Auto Stageas have a separate trans cooler from factory (located in between the rad and intercooler in my previous post/message).   Currently looking at Fenix $460, Blitz $700, GReddy $800, and KoyoRad $740. What are everyones thought on Fenix ( ive read a few comments saying theyre cheap Chinese rebrands etc and how their build quality is... well.. chinese...)  compared to the others? Worth the extra couple hundies?
    • Man, different parts but the same numbers is terrible @dbm7! And it doesn't help that most online shops don't list the part numbers at all. They just give a list of compatible models...
    • Slow when hot could also be because its getting more dynamic compression, OR things are getting a bit tighter once it is all expanded. If it were an earthing issue, typically I'd expect you to have it have issues all the time. Unless it's really a combination of both things. Where the higher compression, and things being a bit tighter, is giving that bit of extra load and you do need a slight clean up on the cables/connections.
    • Yeah, this is one of the most annoying things about nissan part numbers... I've got an unrelated example... Image is of the AT output shaft ~ they have the same part#, but clearly the shaft on the left is beefier design to that on the right ...the difference (essentially) is the 'lighter' shaft on the right, is for engines up to RB25DE (this includes RB20 variants) : the shaft on the left is for RB25/26DET(T)....are they interchangeable? Yes...but obviously one shaft is going to be stronger than the other...and, the lighter shaft is around USD115, but the heavier shaft closer to USD150...same part#... ...epc-data usually tells a tale ~ the amayama listing for 39100-23U60 has a note "Longest side is between 60 and 105 cm" ; no such info is there for 39100-23U70 ...and given the great disparity in price between the 2 parts, it makes me at least curious (to the point of caution) where the 'extra money' went? ...ie; these 2 parts have a cost difference that (to myself at least) isn't explained by 'plastic boot'...ie; with amayama there's AUD700 price difference ...plastic versus rubber?...I'm not seeing it like that...and 60cm ~ 105cm...??...that's a huge disparity....something hinky going on here... I'd try searching by VIN, not model... /2cents
