The diffence between the two are GTR measure 296 x 32 and GTS measure 280 x 30

I upgraded to GTR front brakes on my GTS and it is a worth while upgrade out on the

race track I had no brake fade at all and they felt very strong and consistent.I still used

the GTS rims (16 x 6.5) GTR are (16 x 8) and the only drama that I had was the the rim

was very close the the Nissan logo on the caliper about 2mm gap so what I did was file

the logo off and repainted them in high temp paint.With after market wheels this won't

be a problem apart from that it is 100% bolt on fit.The rear brakes on the GTS are the

same as early model GTR's same part number on the rotors and pads.

I think your money would be better spent on good pads, and when the 280mm rotor screams enoough then consider changing to another Skyline brake setup then, but i think you will find that on the street you wont notice any difference at all. A

At the track, if you go then i think again you will be hard pressed to tell the difference between the setups if you are running the same pads. But no doubt it is a good upgrade but maybe not so budget by the time you buy the GTR calipers, buy new rotors, and throw your pads in there it is probably a $1000 upgrade,

Not meaning to sidetrack this at all but a semi-relevant question..

Roy, What do you think are the biggest brakes to fit on the front of a gtst/gts4 under a 17x8 rim (unsure of offset but all inside guard)?

Currently I am running r32 gtr sumitomos with 296 rotors. I am thinking of going to dogbones and 324 rotors with these callipers.. do you have an opinion on this?

James.

Yeh, the 324mm will fit under majority of 17" wheels, I know i have never had a set of wheels that have clashed with my 324mm setup, and i have probably had 8-10 set of wheels on the car.

Biggest problem i have had is going to an aftermaket caliper with 330-343mm rotors which is when it becomes dependant on wheel types and quality, along with offsets etc.

33gtst setup is pretty much the same as 32gtr but a tad heavier, I'm running them but I put braided lines and a master cyl stopper in at the same time so can't really comment on just the calliper/rotor upgrade.

I don't know what people charge for 32gtr brakes but 33gtst would do the job without the gtr tax..

Alcon make 343mm, CSC/B-spec make 343mm. Performance friction also make 343mm. Project U make 345mm. RDD made 343mm, Biot make 340mm. Brembo/Stoptech/Dixcel all make 332mm. Alcon, AP and Wilwood all make 330mm. Just Jap and the G4/K-sport along with Greddy do a 330mm rotor as well. Then you have a bucket load of people making 324mm replacement rotors for GTRs and Supras

After getting halfway through this project, and then finding that I needed to remove both front driveshafts as 3x cv boots were stuffed and had to be repaired in between, It seems that I have a rare set of 17" rims that the 324mm discs and caliper adapters will not fit under..

Seems that the inner diameter of these gmax m100 rims are just too close.

Just a heads up for anyone else heading this route. Now I have to work out which way to go.

ffs.

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      By Duncan · Posted

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)
