Seeing the red900ss made me think. A lot of bikes have cross-drilled disc rotors and yet cracking, even under extreme race conditions, does not seem an issue. I understand the weight differences however after a few laps I am sure the heat factor is similar to cars. Food for thought or just demented ramblings?

Hey dbasteve...any news on the rotors?

The castings still haven't been machined. Production is a bit of a bottleneck at the moment because of some big orders going through. I'll keep pushing for this month though.:D

The part number is DBA 963 for this GTST R33 rotor.

Any idea when the kpaw design kicks in for slotted 909 and 908 models?

No rush either just trying to plan things :)

The DBA 908 K/Paw are in stock, the DBA 909's will change over next production run which could be a few months now. We still have heaps left from our last run.

Looking at the sizes, can't see anything else fitting the front...

What's ure impressions on the kpaw design compared to the normal 1s?

In regards to the 909;

The 909 has been around for a long time and is a very heavy duty disc. To change it over to the new skippy design would enable us to reduce the weight of the disc and maintain or improve stability and strength. The pillar system offers a better distribution of support between the two braking surfaces and more surface area for better cooling. I wouldn't say it will make as big an improvement on the 909 as it would for a lighter duty disc but there will be an enhancement.

Hey steve, just read the entire post and am a fair bit confused by the whole thing.

I have a '95 R33 GTS-T, i want your slotted rotors front and rear with the 'skippy paw' ventillation.

I've searched your website and found part numbers:

FT: 926

RR: 908.

Questions:

1. are they both the kangaroo paw system now?

2. how can i tell if my car was 32mm min thickness 30 OR 30mm min 28?

3. all the R33 GTS-Ts have 296mm diameter front discs, right?

Thanks for your time.

Not half as confused as I was sifting through this mess.

O.K There are two 296mm discs out there;

1. DBA 926 = 296mm x 32mm R32 GTR RB26DETT (Soon to be listed as DBA 4926)

2. DBA 4963 = 296mm x 30mm R33 GTST RB25DET

3. DBA 908 = Rear for all non Brembo brake kits for R32 to R34 GTR and GTST

a. All of the above are Skippy rotors (K/Paw)

b. Your car will be the DBA 4963. The catalogue is wrong as the 32mm rotor only fits the GTR.

c. There is one other oddball GT with 310mm rotors. I haven't seen one in Australia yet.

All the above discs are in stock.

We decided to only make the new front Skyline rotors as 4000 series rotors. Considering the application, there was no point making stock standard product to compete with imported chinese product.

The prices haven't changed but if you order a DBA 963 you will get a 4963 which is our premium one piece GTP and Rally class rotor spec.

I hope this helps clear things up. Even though I've probably added a bit more to the confusion with the last bit.. :rolleyes:

Is there any other alternative to using 909s on a r32 gtst?

Thanks again for all the time uve spent helping out here :D

I'm doing my best to push it through!

For every one disc we tool up for or rebuild we get 10 more requests. :eek:

Steve,

I was wondering if you knew anything about changing brakes from a R33/34 GTR onto the R32 GTR. Is it worth the upgrade or am I better off with something more exotic like AP or Alcon calipers?

I'm keen on a set of the dba5000 rotors. And sorry for bugging you again.;)

Thanks

I haven't done it myself. I am told that you need to replace the struts, but I can't see why unless there is a unusual clearance problem. The offset is the same but the R33 GTR rotor is 30mm instead of 32mm.

If your in Sydney you are welcome to borrow a sample rotor over the weekend or something. You would need to check out the R33 caliper or it may be more ecconomical to use a radial mount Brembo of similar spec and have a bracket made. There are quite a few good Brembo calipers that aren't too expensive. The AP's and Alcons are excellent but quite expensive.

Do you plan on doing this upgrade yourself or having it done in a workshop?

DBA 5000;

There isn't enough clearance between the caliper and hub to allow a conventional two piece design on the R32 GTR rotor. It can be done using a castle drive system which is very expensive to do correctly and you really couldn't justify the cost over an R33 upgrade.

If it is done properly, Yes it can make a difference in racing applications. For the street; I don't think it's as much a benefit.

I assume you are refering to the article in "Zoom" a few weeks back.

You can email me if you would like a more in depth explanation.

    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
