Here's an example on my old rims, and yes in this photo the front is clearly higher than the rear as it's on a slope too.
That said, if the front was lower, it'd tuck further in, but I can't really find anything more conclusive. Clearly the above photos are gonna work if you're a coupe, and everything on the internet I have found says the front track is 10mm wider than the rear track on a 34 GTT.

So I could just be fkin wrong lol. However, I definitely don't need a spacer on the rear with a 9+30, so perhaps the coupe does have a little more space in the guards.

I guess the rear quarters on the coupe poke out 10mm further than the sedan's rear quarters

I always thought the coupe rear guards were wider. 
I also had 2 different guard rollers tell me the sedan rear guards could be rolled but not pumped as it buckles the door latch and affects the rear door - unlike the coupe

all this is doing is making me more confused over sedan 34 fitment haha

This has been my thoughts for the past few months looking at fitment hahah I thought I had it worked out but now I'm a bit confused again

I avoided getting the 10 inch rear because I wasn't comfortable risking having to roll my guards so I got a square setup of 18x9 +30 and put an extra 5mm slip on hub centric spacer on the rear

I reckon it needs just about 2mm more on the rear to be perfect

My tyres are square too at 245/40/18

Hopefully one of these pictures gives you an idea of fitment

That helps heaps man thanks.

Putting it in a offset calculator going from 9+30 to 10+38: The wheel will extend (poke) out 5mm more. So that should put me into the same fitment as yours with the spacers. That decides it all for me.

18x9+30 Fronts

18x10+38 Rear

245/40/18 for the fronts and I guess I'll run like a 260 something on the rear.

Nice car as well. Like the look of more meat on the tyres opposed to the crazy stretch lots of people are rolling

What style rim are you getting

Went and test fitted a 18x9.5 with a +20 offset on the rear of a r34 gtt coupe with coilovers, lowered but legal height and no guards rolled. Rims stuck out of the guard quite abit, so +20 is definitely a no go. 

 

Ordered for the front 18x8.5 +28 and for the rears18×9.5 + 35 

Unsure of the tyre size, most likely a 235/40/18 at the front and probably a 265/35/18 rear. Rota wheels expert who supposedly knows all about our cars, is going to call me on monday and recommend me either 18x10+35 or 18×9.5+35 with either 265 or 275 tyres on the rear.

  • 1 month later...

Hi, does anyone know if a 18x9.5 +22 265/35 square setup will fit a r34 gtt coupe?

I'm looking for a set of SSR GTX01 and I would like to run this size for the concave look. I don't like streched tires so thats why i chose 265/35 on a 9.5j

Hope anyone can help me.

Thanks!

Thanks for the info.

Would you reckon the same setup with +40 offset will fit? Or do I need to go to 18x8.5 in the front?

a 265 is far too big on the front and with a +40 offset you’ll likely have issues clearing suspension - especially on full lock.

 

8.5 is better if you don’t want stretch tyres, a 235 will fit nicely. +22, definitely not +40 or the wheel will be far too recessed inside the guards

265's can fit. I have them all round on an 18x9 +30.

They will pretty much only fit in that space. I also had them in the past with 18x9.5 +27 (because the tyre was mounted in the same spot, centrally speaking).

Mind you, you will want to roll guards, make sure your liners are absolutely clipped in, and potentially relocate the driver side loom under the right/driver side front quarter panel, because you can/will rub through it if your springs aren't ultra rock hard.

Will your life be a hell of a lot easier with a 8.5in rim and a 255? Yes.

 

Thanks for the replies.

Think I will go for

Front: 18x8.5 +44 (245/40)

Rear: 18x9.5 +40 (265/35)

I've compared this setup to some others and I think it will look good and clears fine.

I know +40 and +44 may seem like a high offset, but the rims I want jump from +22 to +40 on the 9.5j and +44 is minimum on 8.5j. Since the +22 will poke out I think the higher offsets will be better. I still need to measure for clearance on the suspension tho.

But like I said I've compared this setup to several others in this forum and it seems to fit fine.

That's because the +44 is for Subaru STI

I'd look at other options, there are wheels of similar style with Nissan RWD offsets.

* edit * looking at the Japanese SSR site

https://www.rd-tanabe.com/ssr/wp/wp-content/uploads/2020/03/GTX01_2020_spec.pdf

There is a 18x8.5 +38 option, which would be a tad better.

    • 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.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
