Hey all and thanks heaps to anyone who replies with helpful and knowledgeable stuff....

I am looking to upgrade/replace my rotors (mainly) as I have been told mine may not pass a RWC inspection.

Basicly I would like to know if the rotors (and brakes) off an R32 GTR will bolt straight onto my R32 GTS4?

And if not, could you please suggest another model option that has been proven to work with a simple switch-a-roo...

Cheers :-)

EDIT: I should also mention I have R33 gtst rims on the car, if that could affect the new rotor or brake size with clearance and whatever :)

Buy a set of R32 GTR calipers and get soem DBA4000 rotors. The GTR rotors you buy with the calipers will want to be in good condition to warrant putting on your car as they will be just as old, possible travelled as many kms, with possibly more spirted driving, and are cross drilled so have been known to crack.

But with the R32 GTR sized rotor and caliper it will be a bolt on upgrade for the front. Dont bother with the rears though, well thats my opinion anyway.

A better buy if you can find them at a reasonable price would be a set of R34GTT brakes. larger 310mm rotor vs 296mm, newer caliper and rotor etc, and 99% sure they are still bolt on. (That last 1% is because i have not done it personally so would still recommend checking im not talking out my a55 before spending you dough:))

Don't worry too much about the calipers. The GT-R rotors tend to crack around the cross-drilled holes, and they really don't contribute that much extra to braking efficiency.

Just get some DBA slotted rotors. (@ www.dba.com.au)

My view on R32GTR brakes is that they don't pull up consistently at the end of a straight after 3 laps on a 35 degree day... :cheers:

That's because you go round the corners too slow. :matrix:

I agree with Roy if you have the money to spend. Seriously though save your money on the cost of a new set of set of calipers. The skyline ones really arent that bad because you'll be forking out big bucks for a different set of calipers. Just go with the DBA's roy suggested above.

Why exactly are you replacing your discs?

Thanks for all the replies guys, keep 'em comming! :-)

I need to do this to get a RWC I am told, my mate thinks (90% positive) my rotors are undersize and need replacing, so I am trying to find a decent replacement which it also low cost....

When you mate says ur rotors are undersize, he means they are too tin, not too small in diameter. So why not just get standard sized DBA4000 rotors? They would be a great upgrade and be a lot cheaper than buying slightly better calipers and new rotors. Maybe even get slotted ones?

Thanks xRHETTx, I will look into those DBA4000 rotors, I just hope they will be cheap as I am a poor uni student....

Yeah I thought "undersize" meant too small diameter, but he soon clued me into the proper meaning....:-P

I was also actually looking into rotors off another skyline, say an R33 as there would be plenty of these around that are not running ie wrecking...but I am not sure what models will be a straight swap onto an R32 GTS4.....

The R32 GTR front rotors for the dba 4000 series are 4926.

However, that's for the gtr made between 6/89 - 8/93.

Between 8/93 and 12/94, they are 4928 becasue they had 324mm diameter rotors.

As for rotors for the gts4, i'd recommend getting dba 4000 series to suit the r32.

The part numbers are: 4909 for the fronts, 4908 for the rears. They are both slotted as the part numbers should also have either SL or SR on each (slotted left, slotted right).

That's what i'll be getting anyway for the gts4. :rant:

As for the price, I was quoted over $900 for the whole set though!!! So, i guess it would be even more expensive for say the gtr brakes as they are bigger! But keep in mind that's the retail price :Pimp2:

      From Japan and back to Europe, my sh*tbox R34 GTT

      By GoHashiriya · Posted

      Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.

      Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?

      I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
