Rotors For A Fat Pig

Hi all.

I'm after a new set of rotors for my M35 Stagea. Already got a set of QFM HPX pads to go in, and will more than likely replace the standard lines with braided ones.

I was all ready to order a set of slotted DBA 4000 rotors, however when doing a bit of research found that a lot of people on here had issues with them cracking some time ago after track days. I was looking at doing an occasional track day or hillclimb once the brakes and suspension were done, so I'd like to upgrade with this in mind. It'll be about 95% street, 5% track.

Not sure if these rotors are still having cracking issues, or if being a 1.8 tonne wagon I'll just emphasize the issues.

What would you recommend as a suitable upgrade? Or can I safely order the DBA 4000 series without killing them?

Hey Mate,

Honestly I think you'll be pissing in the wind with the Std Braking system. I know you can get uprated pads and rotors for them, but in reality, I think your better off using something a bit better out of the nissan stable.

The single piston, thin rotors they come with really are not up to the job of stopping these beasts!

See if you can get a front set of either GTR brembo's, or if thats too pricy, go to the R32 GTR/ R33 GTS-t 4pot Sumitomos.

These provide better Pad/rotor Choice as well.

Just my opinion.

Thanks for the feedback guys.

I think I'm going to go with an upgrade to the stock system for now. At first I was just looking for a simple upgrade to the stock setup, and didn't want to bugger around with getting different setups engineered.

Now that we're looking at doing more track days, hillclimbs, etc, the stock system may not be good enough, but it will be interesting viewing for people now that we're shooting it all for the web site.

I can already see you being right mystery_kid, but we'll bake the HPXs now that I've got them before switching to the A1RMs.

So the upgrade for now is a set of DBA 4000 series rotors in the new Clubspec T3 design, which we will be evaluating for DBA, the QFM HPX pads and a set of Stoptech braided lines.

Still trying to get my head around brake fluids, but I think it'll either be the Valvoline Performance DOT4 or the Motul RBF600.

Depending on how this setup goes we may move to 350Z/GTR Brembos Alex, but it'll be a worthwhile exercise either way I think, now that we're doing some evaluation work and some write ups/videos on what we learn.

You would be surprised at how well the stock brakes can work with a few upgrades. I've got the slotted DBA4000 series rotors in my C34 S1 with Maltech lines, Motul RBF600 and Dixcel (jap brand) pads. The pad choice came down to availability at the time a couple of years ago as there wern't many choices for S1's back then here in Aus and I kind of bought them blind (seeing as I don't read Japanese) so I can't tell you the specs of the pad but I was surprised at how well the combo preformed on what you could say is a piss weak system compared to the rest of the Nissan lineup. Cold performance is not as good as I'd like but once you get some heat in the brakes they can take a fair amount of punishment. I have been able to get them to fade during some spirited mountain driving but for what the system is it does well. And as for cracking I haven't had any issues in the couple of years I've had them.

      LOL.... a good amount of people (not all) on that continent seem to know everything and like to measure things in bananas, football fields, statue of liberties instead of the metric system lol.

      M35 Aftermarket Fuel Pump

      By dawhitehonky · Posted

      I assume the modules are similar enough, so if you've had no issues I don't see why I would. I have tried to find a wiring diagram for the FPCM / fuel pump circuit, but I can't find it anywhere. Otherwise, I would just do some wire cutting and joining at the FPCM and give the 12 V supplied to the FPCM directly to the pump instead. If you know anyone that could help with wiring diagrams, I'd be very happy

      If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.

      Rapid-fire squeaking/creaking from rear suspension

      By GTSBoy · Posted

      Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.

      Jacks that fit under GTR lips that can reach the subframe?

      Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
