Hey guys, first post here. I've tried digging around on American forums but I keep finding conflicting information.

I was looking at replacing my brake pads until I noticed something had cut a groove into two rotors, and then noticed another one had decent wear :(

I'm looking to replace my front and rear rotors, but the sizing keeps changing between places. Places like Supercheap auto list the sizing as 326mm for front Brembo, 320mm or 296mm for normal and 292 at the rear. However one American forums lists 12.6(320.04mm) at the front and 12.1(307.32mm) at the rear.

At this point I'm completely clueless on which size is correct and all I can think of is pulling a rotor from the front and back and just measuring it.

 

Any info would be appreciated.

Sorry I can't confidently answer the correct size....but I can say that pulling a rotor off and measuring diameter, thickness and offset (distance from bottom of disc to top of hat) is a good idea, because that way you can't go wrong. 

DBA website has a good catalogue to cross check once you have those measurements, often you can find a match against another Nissan of the same age if your model details are not there

Welcome to the group!

First question.. do you have twin piston callipers on the front?

Twins look like this -

If So, you have the upsized brakes that came with the series 2/3.  Sadly many parts suppliers refuse to acknowledge this and list the smaller rotors for all V35s.

The front rotor size is 320mm and the rear is 308mm.  The rear pads are the same as the earlier models, but the front pads are different.

You should be able to look up the non-brembo brakes for the 2005+ 350Z to get the correct specs.

However, if you have the single piston front brakes like this -

Then you have the smaller 296 front 292 rear rotors.

I order mine from the states many years ago and when i got them they where to big. 👎

Got them machined down to fit in the end. Painful ordeal 😵

Best to get your measured because there are a few different sizes. Even the info on old threads in this forum are conflicting too.

Cheers man! Good to find fellow like mined V35 lovers.

Definitely rocking twin piston. And that's a huge pain with vendors. 

Crud now I'm worried. I ordered pads from Z1. Hawk Performance. They did say it'd fit the twin pistons though so hoping they'll be fine.

Would any 2005+ work? I think a tour or track version existed at some point so I'm imagining some variations won't do the job. Edit: Scratch that, saw they had different sizes 😅

 

Question about how the sizing works. So for these https://www.supercheapauto.co.nz/p/dba-street-t2-slot-kp-nissan-350z-05--f-/SPO7423864.html?cgid=SCN01080117&vid=OBmEBn9ZtK3rMhgNDCxRgA%3D%3D#vid=OBmEBn9ZtK3rMhgNDCxRgA%3D%3D&start=3

They say 320mm, so they should do the job. However I'm confused on the 11/2004 --> portion.

Oooof that would've been nasty. Trying to avoid any pain here lmao.

 

But yeah seems it's best to pull one of each rotor and check 😮💨

They should be correct for all V35 models from nov 2004 onwards (except brembo option)

Look up your car on here.. it seems to be fairly accurate -

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
