Putting one of these into my S13, but unsure what D Bush to buy. SuperPro has them up to 24mm, but the bar seems to be 25mm (admittedly measured with adjusting shifter with measuring marks, tape backs this up but both could be 1mm out). I've also read some people state t's 26mm. Nolathane lists odd sizes.

Can any shed one some light on this?

Also do I need to use grease on the bushes when installing them? Seems to be a lot o conjecture around this also.

Um, Shirley this is a function of the actual bar that you have in your possession, and not something that anyone else can know?! Buy cheap plastic vernier calipers from Bunnings or Jaycar, measure and revel in your newfound ability to correctly measure this stuff.

As to the lube - any time urethane touches metal, moly grease goes in there.

Are you telling me Nissan just randomly put different sizes rear swaybars in the back of all their cars... surely there's a factory size.

Not grease - special lube.

I have Lithium grease, good enough or is it something more specific and does it normally come with the bushes?

I use moly grease on all urethane bushes. Always have. Always will.

OK, but now you tell us that it's factory. You didn't before. And I'm pretty sure that the factory GTR bar probably isn't that large, although I'm willing to stipulate that it might be. See below for comment on that. The manual GTSt one is ~17 or 18mm or something, the auto GTSt one is only ~13mm. Stiffness goes up with the 4th power of diameter, so 24mm is a hell of a lot stiffer than 18mm, even if comparing hollow with solid.

The heavy duty Whiteline GTR rear bar is 24mm. Not a real big step up from a factory 24mm bar.

Try the Nolathane site again. Do the Make/Model search

You will find rear sway bar mount bushing and it will be an ID of 18mm (part#42478)

The rear sway bar you have is likely aftermarket and requires 24mm.

I'll have to get some moly grease then, I only have generic heavy duty industrial and lithium at home.

The bar is definitely 24mm+ I'll buy some verniers and confirm.

Yeah I found the 18mm one, but this is much larger.

It could be after market but it was sold as having been removed from a 32 GT-R that was being wrecked, the colour/age implies that also. The same smokey black colour as all the others I've seen where as almost every after market bar I've ever seen was anything but black.

The size surprised me too, concerned it's going to be too stiff for a grip setup.

Just use the lithium grease

Shouldn't use a petroleum based grease on poly - many petroleum greases have moly in them, so I'm surprised that just a "moly" grease would be any good.

Lithium grease is made for situations where petroleum greases are not suitable, so perfect for poly bushes.

.

Edit: just had a quick search, and it looks like some (maybe most) moly greases are used in a lithium grease base. These would be OK. I know that they used to put moly into petroleum based greases (when I first came across moly greases 20 odd years ago) so guessed that this was still the case.

Just make sure that whatever grease you use has a lithium base and all should be good.

Define "too wide". As in "too wide such that if I cut some off it it would be fine"?

FWIW, when I put the 24mm bar on the front of my R32, I spent about a half hour going back and forth between the car and the pedestal buff removing material from the outside of the bracket bushes so that they would fit inside the brackets.

      What brakes on R34 GTT(Europe)

      By Duncan · Posted

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      What brakes on R34 GTT(Europe)

      By Kapr · Posted

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.

      Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.
