:happy: So, 2 weeks on and no news ? BTW, do you still have our money or do they ? :ninja:

Your money is safe with me. I never hand it over to them until they charge my account.

I need to play it safe for everyone's sake.

What I'm worried of is something has happened since the whole economy went into resession.

I rang and didn't get through yesterday, only a voice mail, will try again some time today.

Whats the chance that they will arrive before the 13th? Ive got a track day on the 14th and one of my front ones is cracked so will be in real shite if they dont show up...

I've left a message on their voicemail asking my contact to call me back. If they process and ship everything by Mon-Tue next week then there's a chance you'll get it before 13th, if not then it will not make it.

Surely SAU alone would keep them in the black :)

Just a word of caution, with heavier vehicles you may notice a lot of rotor wear on the fronts. My front rotors lasted the same time as the pads.

I have read that the RDA rotor are designed and manufactured to be a little softer to give better bite and stopping power but at the expense of rotor life.

They're cheap anyway so why not............

Interested to know what car have you got when this happened. I had someone said their 300ZX front rotors (gold passivated) also wears out very quick.

Oh and was yours slotted or the gold passivated grooved/dimpled?

I personally have used it on the front of R33 Gtst without any premature use (even tracked it - with greenstuff which is not really for track pads),

and currently on a V35 with redstuff pads - but I have only done 5000km in my V35 so hard to say...

So perhaps the gold passivated one is 'softer' than slotted...

This happened on my VX Calais which is quite a heavy car (read "slug") :P . The V35 is only 100 odd kg lighter so could be a candidate, although I've read it is a much better balanced vehicle so may not suffer the same fate.

the rotors were the slotted non-passivated. I've got the passivated slotted on now and well see how that goes. Has anyone tried the moly rotors?

I am trying on the passivated rotors. If it's right then it's softer than the slotted but so far I haven't had any issues yet.

But again, V35 Skyline is 1590 kg and in a coupe the weight distribution is 53/47 front to back (in sedan it's 52/48).

It has 296mm front and 292mm rear in touring trim (non brembo) or 324mm front and 322mm rear in track / brembo form.

I have the later (brembo) size

A guy in his 300ZX said his car has 80/20 brake bias front to rear, unsure of static weight distribution on 300ZX though,

anyone know what are the brake usage on 300ZX? Worn his gold passivated rotors fairly quick as well.

The Z32 turbo has 280mm front and 297mm rear, same sizes like R32 Gtst, but I'm sure the Z32 with VG30DETT engine weighs

a lot more at the front than a single turbo R32 with RB20DET.

R32 Gts-t weighs 1260kg manual or 1280kg auto according to my JDM brochure, 300ZX is 1460kg in hatchback

or 1560kg in convertible ( targa roof ? ) form, so it is a much heavier car with an undersized OEM brakes - in my opinion

Added: as a comparison a 1340kg (man) / 1390kg (auto) R33 Gtst which is still lighter than 300ZX is already equipped with 296mm / 297mm rotors by standard. bigger diameter would logically mean less effort required to stop the car on daily use, and logically would mean the rotor should last longer.

ive got R32 gtst front brakes on my r31 with the rda slotted rotors and bendix ultimate pads (average). been on for bout year and a half now, pads are about 40% and the rotors are lipped (only slightly though definately machinable) this is mainly street driving. so yeah the rotors arent the longest lasting rotors there are.

btw did you get prices on R33 na rotors? pretty keen..

how many kms is that? just to give a rough idea how long they will last...

my stock V35 OEM front rotors were less than minimum legal - that was I assumed 49000km never replaced from japan, on a stock pads. didn't pass RWC, I needed to get a new set. The rear was lipped but legal (machineable).

I'll check on NA R33 rotors - forgotten about it.

      R32 non hicas power steering solenoid issues!

      By D.phantom · Posted

      So I’m having issues with my power steering. the obvious heavy and light and comes on and off randomly now it’s constantly heavy. I’ve read through forums regarding this issue and what I’ve gather is that it’s referring to hicas deletion. That’s the problem mine didn’t come with hicas.    I’ve rebuilt the steering rack, pump, changed the bent hardline on the rack and taken out the solenoid to clean and loosen up the actuator, applied 12v to get it moving. Roughly checked the loom to see if there’s any damage to the loom and nothing. Now I’m checking the wiring. I’ve tested the wiring to the solenoid and it’s fluctuating between 0.07v to 0.03v. Does anyone know what it’s supposed to be reading? 5v? Anyone one know how this all works? Is there a fuse in between? What else is it connected to? How does it connect to the speed sensor? A resistor fried in the ecu? Please help. It’s been years Thanks in advance

      Chips/Dents in wheels

      By niZmO_Man · Posted

      that's pretty good condition, those chips are nothing. Get a mobile repairer to sort it out. Nice wheels, I had white 17's on my GT-R once, looked nice.

      3D printing fun

      By Sean'O · Posted

      Howdy friends, So this evening I had a need to remove the rear compressor turbo pipe (long story, but I'm replacing it due to a bolt snapping off in the pipe and managing to then snap an extraction bit in the broken bolt, fun times -_-). The rear bolt is a bit of a bastard and very little room to get good leverage. I was able to get a 12 mm socket onto the bolt head, but none of my ratchets were able to fit, so I put together a "stubby" socket wrench to get it out and it worked surprisingly well 🙂. In the past I've "made" tools by cutting down spanners and bending them with a torch etc, but this 3D printed wrench was way less effort. I'll be keeping this one in my "special tool draw" from now on for sure ^_^b https://www.printables.com/model/868973-half-inch-stubby-socket-wrench
