Hey guys,

Looking at getting some of these late in the year, JDMconcept told me that this customer had the 18x9.0 +30 and 18x10 +38 but weren't sure on tyre size. Is the owner on here or anybody know what he would be running?

Looks like a 245/40 front and 265/35 rear

might be 255 rear but 265 should fit easy, could even probably work a half to full degree positive camber if you’re making some power to put to ground.

always best to check clearance to your suspension as that will be the deciding factor

I bought that specific set couple months ago for my 34. The tyres I went with where 235/40/18 on the front and 255/35/18 on the rear. Easily could go 265 on rear. I will say I dont think the offset is aggressive enough though. If I could go back I would get a more aggressive offset for the rear.

Agreed but I believe it is a fairly safe size if you want to mount fat tyres

the white r34 is probably running spacers.

to get that flush finish with some tyre stretch it’s best to use a 9.5 wide wheel with +15-20 offset. You can make a 235 stretch nicely and still fit a 255 at the back. Seems to be a fairly common size amongst most brands

Cheers, wanting as flush as possible but dont want to draw attention with them sitting outside the guards. Just went through 6 months of defect/engineering because the last wheels were too phat haha.

they were 9.5+15 all round and had 235's on them. 

Making ~305kw at the wheels so want some rubber on the back but doesn't have to be crazy.

Edited by Moshpit95

I have managed to fit 265's all round on 18x9 +30's on all 4. There's a ton of room for more rubber at the back, I have something like 35mm of inside clearance. Fronts are pretty tight, in a "Yeah you'll need to get it rolled/yeah you'd better think about relocating the loom under the driver side fender" kind of thing.

I used to have 18x9.5 +27 with a 265 there too, unsure as to which setup went through the plastic. Maybe both did, and maybe a 255/35/18 is a better idea on the front ?

Yeah I've read that there is heaps of room up the back.

I just want to make sure the wheels will be flush if im dropping 2k+ on them haha, after scouring through forums all over the place I thought these were the answer. Guess Ill keep looking.

So im looking at getting rota p45f for the fronts and p45r2 for the rears, but i really don't know much about the offset choices, hopefully someone can help.

 

I am looking at getting the following rim and tyre sizes:

18x8.5 front with 245/40/18

18x9.5 rear with 265/35/18

The rota website only offers +28 offset for the fronts and either +12 +20 or +35 for the rears. I have bc br coilovers and i am lowered to the maximum legal height in Victoria. I'd like my wheels to sit just slightly inside the guards, not outside, as i use this car for track days. 

Would +28 for the fronts and +35 for the rears be ideal?

 

 

Yes.

The front will tuck 1mm more than a 9+30, rear will be +1mm pokey vs a 9+30, but people run 10+38 on the rear all the time (with is +4mm of poke in the same example vs 9+30)

They will fit. You will likely need to roll guards in order to fit them depending on how much tyre you want on said rims.

This is a square set of 18x9.5j wide +20 offset.

235 tyre front, 255 tyre rear. 
rolled guards, no camber

any chance of 10.5 +30 fitting on the rear of a r34 sedan?

and 9.5 +23 front?

It will sit 2.5mm out more than the photos I posted above with the bronze work xt7’s

below is a couple more pics of my sedan with 18x9.5j +20 fronts, 235/40 tyre

18x10.5j +25 rears, 275/35 tyre.

as you can see the tyre is poking out a bit too much at the rears and caused scrubbing which resulted in me getting 2 degrees negative camber as opposed to 255/35 tyres which would be a better solution and also match the stretch on the front

If you have a widebody, sure.

Both will sit out about 15-20mm from the guard.

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 is bizarre. I have 18x9 +30 and I need rolls to clear..

Also the rear on the 34 pokes out more than the front. At least it does with the Sedan, perhaps the coupe IS different!

(I have 265 tyres on all 4)

I'm at 340mm rear eyebrow height with no camber arms maybe that might have something to do with it?

Nope, my car is higher than yours too, and I have only -1.5 deg camber at the back - It could be tyres in my case.

Its worth mentioning that the rear pokes a good 10mm more than the front, for the same fitment which I found suprising! I could take pictures of how it sits, mind you its been out in the weather for a month now ?

Strange as the fronts definitely poked more from the guards when I was running 9.5j +20 square set up on my sedan. Pics above with the xt7’s should confirm.

must be difference in coil overs?

    • I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.  
    • Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
    • You can use your VIN to look up the factory part number somewhere like amayama, and then look to order new if necessary. https://www.amayama.com/en/genuine-catalogs/nissan Depending on price you might want to rebuild instead. @GTSBoy I had an interesting insight into US market parts when the Titan rear calipers were sticking. New calipers were dirt cheap, about 20% more than a rebuild kit....they are just considered throw away maintenance items
    • Funny, but really not funny. Thank god (most) f the world has moved on since then
    • Lots of votes for driving onto a plank first; that is the quickest way I've found, 25mm is enough for my case but that will vary by car It also depends where you are going for. On the 32 I can get to the rear diff with my floor jack if I do that end first, and get it up on stands. Then I lift the front from either front tow hook as high as needed, also onto stands. Sometimes I need a small lift on the other tow hook to get it level enough If I do the front first I can't get to the rear diff because of the angle of the car Other options are getting to the front mount of the rear subframe from in front of the wheel (if only lifting one side, or just do both which is a bit of a pain compared to one lift from the diff), or also the gearbox cross member mount on the driver's side if you are  just trying to lift the driver's side. I This is the jack I use; it says 75mm clearance but of course that is only on the lower section so if you have to reach too far in like the diff you still get stuck. https://www.snapon-bluepoint.com.sg/category/Floor-Jacks/product/Floor-Jack,-2-Ton-Low-Profile
