Travis, you're completely missing the point. The Autosport ones ONLY suit calipers that came on cars with 296mm rotors. The cheaper ones from eBay are designed to suit calipers from cars with 280mm rotors. If you look carefully at the two different adaptors you will see that they are completely different design. The cheaper ones just push the 280mm legged caliper out to the 324mm rotor position. It does that radially. The Autosport one pushes the 296mm legged caliper out to the 324mm rotor position also, but because there's not enough room to do this purely radially, the adaptor also has to move the caliper around circumfrentially a little to provide room for both sets of fasteners. THIS is the giveaway that tells you you're not looking at the same thing. If you apply the 280-324 adaptor to the 296mm caliper, it will push it out even further than the 324mm position. About 340mm in fact. It is important to remember that the Z32 uses the same sized caliper as the R32, not the R33.

^^This guy knows.

I've actually got a few different types drawn up, if there is enough interest I can go talk to a laser cutter :thumbsup:

showing interest for r33 gts-t to suit 350z rotors as they're much cheaper and can be easily sourced from the US compared to R34 GTR 324mm rotors

rough idea on approx cost??

Laser cutter?

Many of the cheaper R33 kits are 3 piece brackets and that in my eyes is pretty nasty compared to the one piece UAS ones

Like I mentioned earlier, if you laser cut the main plate, then what are effecively thick ass washers to match the thickness of your hub then those setups often cause vibrations in the pedal as tolerances are far easier to get wrong. Well thats been my experience at least with some R33s I have driven with that setup.

Its just a note of caution as people have been able to get the setup to work fine.....but is another reason why I like the UAS one piece machined ones

No idea, hence why I said if there was enough interest I will go out of my way to find out :)

Is 350Z brembo the same offset as skyline? I know the stock 350z discs we use on the Stageas are a different offset to the skyline discs.

The ones I have been running (for several years) have the spacers welded to the brackets, have seen the loose spacer types which would be easier to make (no welding) and easier to change offsets according to what disc you want to run.

I made my own 10 years ago out of some 8mm steel plate and welded on lugs before you could buy adapters. Scabbed the steel so they cost $0. Weight wasn't issue due to the small amount used. Only took half hour to make after a few hours making a mdf template. Also had less pad overhang than bought adapters you get today. GTST to GTR rotors. Recommend giving it a go! Mine survived many track and few drift days without ever loosening.

hey guys,

just spoke with GK-TECH (sponsor on here) as he just finished a set for Z32/R32/S14/S15 brakes to run 324mm rotors, and i've asked him to speak with his engineer to see if he can make a set to suit R33 GTST calipers with either 324 or 330mm rotors.

Will report back with (hopefully) good news. :thumbsup:

It would be interesting to see whether they can do something for a lower price than the UAS version; I'd definitely be interested :thumbsup:

dori34 the 350z brembo type rotors you mentioned above, are they the same hat offset as 324mm gtr rotors?

The 350Z brembo and GTR Brembo use a different hat offset. From memory, the GTR Brembo is 54mm and the 350Z Brembo is 49mm.

350Z Brembo Rotors are almost always significantly cheaper than the GTR version.

how does the hat offset make a difference when fitting? (noob Q here)

Well GK-TECH is selling the Z32/R32/S14/S15 adapters for $99.

and he did mention about one store selling the R33 GTST adapters for $350 is a bit rich and his cost will be well below this.

so take that as a hint it will be decently priced like all his gear :thumbsup:

$99 is a good price, but that particular adapter is fairly straightforward. It's literally a rectangular block with a step, two threaded holes, and two through holes :thumbsup:

The hat offset is the distance from the wheel mounting face of the disc rotor; to the front braking surface of the rotor.

This dimension dictates where the Caliper needs to sit in relation to the hub face; and therefore the thickness of the mounting spacer.

:yes:

I was going to swap my 324mm package over to my 34 but I managed to get a GT-V so it already has the 310mm brakes, seems like a lot of effort for only 14mm increase in OD.

Anyone know of an 337-340mm rotor with a similar offset?

There are loads of options if you want 2pce. If you want single piece then a little more limited. About the cheapest I could find was a modified Mercedes ML rotor that was 340-343mm, but needed some machining to suit a Nissan. All up it was only going to be about $450 pair.

That is the only generic option you have. If you want to go 355mm then there are loads of opptions but the suitability of the Sumitomo caliper is questionable

330mm nissan rotor

334mm toyota/lexus rotor

334mm vw golf R32 two-piece rotor (offset is very little though)

340mm audi tt-s rotor

345mm merc rotor

345mm audi rotor (3 different offsets)

make up your mind :)

Agreed, fitment under my rims would probably be an issue at that size too.

There is a bloke db power I think it is that sells an adaptor and rotor kit, bout 700 delivered to Aus. Mild steel adaptors and 345mm brembo rotors. Does one for 33 gtst, 32 and one for S15 etc.

Yep, he uses OE replacement rotors off W163 Merc ML, so if you find rotors locally, you can save money on delivery and order brackets only. Rotors will have to be modified - mounting redrilled to 5x114.3 and hub hole extended to 68mm.

    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
    • Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
