Hi all,

Im about to purchase some wheels for my r34.

front: 18 x 9.5 + 20

rear: 18 x 10 + 15

car is a r34 gt-v

Has kyb coilovers.

Now my questions are:

How much will effort will i need to make these fit?

I know ill need rolling but also flaring of guards.?

Would hicas be affected on the rear?

what tyre sizes would be ideal?

would i need to run camber? etc.

Any help from people running similar sizes/offsets or any good info will be appreciated.

Thanks in advance,

Ang.

Those are some wide wheels mate lol

How much will effort will i need to make these fit? a bit of time and money will have to be put into it - a good weekends worth

I know ill need rolling but also flaring of guards.? not if you run crazy stretch and camber both front and rear - prob easier to and more beneficial to get camber arms than f*k with flaring the guards

Would hicas be affected on the rear? no idea bro

what tyre sizes would be ideal? 225/35/18 on the front. thats a fair bit of stretch and you will still need a touch of camber. 235/40/18 on the rear + couple of degrees of camber

would i need to run camber? etc. Oath.

Hope i was some help mate, im no wheel fitting wizard but i have played with a few sets of different sizes/offsets/tyre sizes on my own cars.

Best of luck, it will look tough as nails

thanks for the reply mate.

I ve finally decided to go with

9.5+20 rear

9.5+35 front with some spacers

with stretched 235/40 all around.

basically id already bought them (rota grids, dont hate :blush:) already but was trying to figure out what sizing to get.

I fitted some 9.5 + 25 on the front and rear yesterday to see what id be up against. front had a bit of scrubbing with the coilovers and the rear sat inside the guard a few mm.

hoping to get a decent stance with what im planning to run.

I'll post some pics when im done for the hell of it.

thanks again pez.

Hey matey, i have the same wheels on my r33, well i have 30offset all round, will be interesting to see how yours fit on the 34.

i would maybe recommend 35 profile on the front, on mine the 40 profile makes the whole diameter just a touch too big, so rubs a bit more and the spacers might not be needed on front depending on how different the 34 is to the 33.

good luck with the fitment, sure are a big wheel , will be an agressive fitment.:thumbsup:

Hey ang, nice buy on the rotas, they should look real nice. When I had the car with gtr rims on I was running 245/40 on 9" +30.

It would occasionally scrub on full lock on the inner guard. Never had any issues of it hitting the coilovers., I think if you go down to 235/35 it shud be ok, maybe even a 235/40 if your gonna use spacers on the front. Are you gonna get camber arms? I was really considering adjusting camber for my rears as the stock camber when lowered puts it inside the guard too much. Either way it should look nuts man, all the best.

looks like you've got it under control Ang!

definitely post pics - they are a TE37 knock off, and there isnt a car that TE37's dont suit

Enjoy

i meant to say i fitted 9.5 + 35 the other day.

now I just have to wait ATLEAST 4 weeks for the new shipment :down:

will post pics on this when on!

awesome, thanks for that info. with the front it did scrub a tiny but that also could be because it was running 245/40 (just because they were on already and wanted a rough idea)

Hope to get an agressive stance.

Thanks again.

is your GTV a sedan? im looking at going 9.5+20 all round'

Nah mate its a coupe.

If the coupe and sedan are the same in regards to offset etc; the front will stick out more than the rear if you have the same offset.

Thats the reason why I didn't go for 9.5+20 all around like your thinking off.

I would rather them be even or the rear be out more so thought this might be the better option.

Thanks maqshood. I was going to text you actually to ask what offset they were but looked them up myself.

Havent really decided on camber arms, hopefully wont need them but I guess I'll find out when im in the process off putting them on.

Hoping for it to look the goods thats for sure, now just have to wait patiently.

they will stick out unless you run alot of negative camber.

rolling/lipping the guards will be needed.

heres mine with 9.5 +20 (front) 10 +23 (7mm slip on) (rear)

the fronts stick out quite a bit (need camber arms to adjust) and the rears are on -3(ithink)

hope this gives you a rough indication on how it will sit on yours.

I have been looking at +22 9.5 for my sedan this is interesting to see how it all sits.

Dori what mods have you done to the front to make it work just a roll and camber or just camber?

Is the roll needed or not needed depending the height of the car or is it so wheels dont stick out guard and my policeman comes for you lol

Cheers

Depends on your ride height.

mine needed to be rolled, it cambered in itself when i lowered it

9.5 +22 on stock height will stick out a bit and the police wont like it lol

Excuse me for thread hijacking with a noobish question but what's this eg. + or - 20 . I'm sure it's offset but I don't understand how you read it.

      3D printing fun

      By Sean'O · Posted

      Howdy friends, So another weird one today, I was looking into replacing some broken clips holding the front grille for the R32 GTR (part number 01553-03831), and noticed the brackets which are supposed to hold the grille in place were also missing 😑. I do recall seeing this issue many years ago, but didn't fix it at the time. A quick look on eBay and I was able to find the genuine brackets, along with all the screws which suited the headlights (part numbers 26042-08U05,26092-08U05). Happy days!....  Once they arrived however there was an extra nut in the packaging which implied that there should also be a bolt or a stud, and sure enough, after a bit of searching I found this thread from 2013, and @Ants clearly shows a stud should be present. Reading around a bit more, it's possible the headlights on my car are the "povo pack" headlights as mentioned by @funkymonkey in this thread way back in 2008. This could explain why the studs are missing on my set of headlights. Looking at the headlight diagram I wasn't able to see a suitable part number for the stud itself. The headlight did indeed have a recess that looked like it would accept a stud, but interestingly no thread or anything obvious how the stud would be affixed to the headlight, I suspect it may have been glued in, press fit, or melted into the plastic at the factory. Another member may be able to clarify if they happen to have a genuine set of N1 headlamps. The only thing we have to work with within the recess is a keyway which likely is there to prevent the stud from rotating within the recess. In any case, back to 3D printing, I put together a model which acts like a pug with a friction fit inside this recess, making use of the keyway so it doesn't rotate while tightening a bolt. Printing in TPU will allow it to slightly swell making a nice snug fit without cracking the part. I've designed the adaptor it to accept an 20 mm M6 bolt (stainless with a cap head in my case), as opposed to the standard M5 stud and I made use of the standard galvanised split washer that came with the genuine brackets from Nissan. Once the bolt and screws were all in place, giving the bracket a gentle shake gave the classic "shaking the car" feeling, very solid, which gives me confidence this is going to be able to hold on much better than the janky solution which seems to have been here for the past decade or so. Overall I'm really pleased with how this turned out and maybe there are more people out there running these headlights without a centre stud at all!

      R32 GTS (RB20DE) clogged cat

      By GabsReDeal · Posted

      Hey everyone, This is my first post apart of the introduction. I tried searching a bit on the forum but couldn't really get a straight answer. I got the car to my mechanic as I felt it being weak. It seems that it was missing on two cylinders due to the injectors. I had all my injectors clean and the car runs much better. The mechanic also confirmed my suspicions that the cat is clogged and needs to be tackled asap. The cat rattles a bit and the hot exhaust warning frequently lights up when driving after getting the injectors clean. In my introduction I was asked about what modification I might be interested in and mentioned a cat delete. From what I was told, this is not really beneficial on the RB20DE and there are more cons than pros.  Could perhaps anyone give some suggestions on what the best course of action would be since the current cat is toast and needs to be removed/replaced anyway? I can also sometimes smell a strong smell of fuel, but I'm not sure if this is related.

      When I was replacing my pump due to being stranded in the wrong state, I went with the Deatschwerks 320lph kit. It is a direct plug in to the stock wires, harness, everything. It comes with a plug... but you can plug the OEM plug directly into this thing. https://justjap.com/products/deatschwerks-dw300-fuel-pump-nissan-s13-silvia-r32-r33-r34-skyline-c34-stagea?currency=AUD Downside: Won't actually flow that much on boost if you want to push it on E85, but it's comparable to the 040/255 etc. Little more actually.
