Hi, new to the forum. Just got a '98 R34 GTT Sedan. Looking to swap out wheels. Is anyone running hub adapters? Looking to fit a set of work meister s1 3p, 18x8.5x10.5 +49. Tires are slightly stretched. Bolt pattern is 5x130 ( they were on my Porsche 944 turbo ). If I get 19mm adapters that go from 5x114 to 5x130 that should give me 20mm offset, correct? My only worry here is if the stock hub studs would be too long, hitting the back of the rim, popping out of the hub adapters. Does anyone know the length the stock hub studs stick out from rotors? Just trying to see if I can make this work. Thanks in advance.

I don't think that that's your only worry.

First up, it's not a problem in itself. If it happens, you just put shorter studs into the original hubs.

Secondly....to try to fit a 10.5" wheel on the back of an R34 is an exercise in getting the offset absolutely perfect. You'd want to be damn sure (measure it yourself 20 times) before committing. Because you don't have the option to do anything except just throw that wheel onto the (probably only choice of) hub adapter, you only have one outcome. Either it fits or it fouls and you probably can't do anything about it if it fouls (beyond guard mods, perhaps coilovers, whatever it takes to find the required space).

I'm running 18x10 +20mm rear on an R34 2 door GTT and it's too wide. It works, just, with 265/23 tyres and rolled fenders. But it would be about perfect at +25mm offset. If I were buying the wheels again - bought originally for my 350z - I would opt for 9.5 rear then f*ck around with a 5mm spacer if necessary. 

Edit: I should add that the coupe has about +10mm body width at the rear fenders.

Need some advice myself.

These are my wheel options

19x8.5 +35

19x8.5 +43

19x9.5A +25

19x9.5A +35

19x10B +25

19x11B +18

 

I'm thinking 19x8.5 35 front and 19x9.5 35 rear
Not many people running 19's, I've mostly seen 18's.  But staying between 30 - 35 offset seems to be the consensus

I'm wondering if I could do 9.5 +25 or 10 +25 in the rear.  

I'm looking for flush, not slamming the car or any camber.

I guess its hard for me to visualize not knowing where the fender is.

What car? Do you not have it in possession?

The reasons I ask are:

  • Obviously it differs between the different models as to what will fit, including choices like strut/coilover choice,
  • It makes no sense to be buying wheels for a car that is not in possession. When you have it in possession, you can actually measure what is on there and how much clearance you have. Then the answers just fall from the sky.

Yes, so then my advice is as I have given in the past. Don't rush it. You don't have to let the excitement make you make bad decisions. You don't have to have the nicest wheels immediately. You can wait a few extra weeks. Get hold of it and measure it yourself.

It is important to realise that the subframe might not be evenly set left-right across the car and you could easily have a 10mm difference left to right. And if you're trying to do this from internet measurements and pushing it to the last mm, you will possibly find yourself with it rubbing on the inside on one side of the car, and on the outside on the other. The only way to win in those circumstances is to go with a more conservative wheel choice, because, while you can put a 5mm spacer on one side, there is no such thing as an "unspacer"** for the other side.

**even if I did manage to convince some numpty that they existed abut 20 years ago.

forgot to mention, R34 GTT Sedan

The car is not with me at the moment, in the shop getting some maintenance work.  I just got it a few weeks ago

I agree with GTSBoy on this, but I will say that 19x10 +25mm will be a stretch on an R34 sedan body. Out of your options, I'd wager the 19x9.5 +25mm as being the closest to perfect (flush), but I'm not considering the implications a 19" wheel will bring over an 18". When you get real close to making it perfect, your alignment settings will have an impact too; I rubbed very slightly on hard corners/rumble strips at -2.5 rear and not at all when set at -3.0.

Just trying to make wheels I already have work. If I cant get the rears to fit properly, Im looking to get Okubo Factory rear fender flares. The adapters have been ordered from Caold in Australia. So itll take a bit to get to me in Hawaii.

Thanks for the specs and pic. So my 10.5x18 at +20mm definitely wont fit. Lol. Lucky I ordered a pair of 15mm and 20mm adapters. Ill keep this post updated Once I get them.

Adapters came in. Got them from Caold Technology in Australia. 20mm in the front and 15mm in the rear. Front looks like it could take another 5mm. Work Mesiter S1 3P 18x9.5 and 18x10.5 +49. Coilovers are Blitz, may go lower a bit but the exhaust is already scraping alot of driveways. 😂

You're right, the front needs about another 5mm and a size wider on the tires. Rear needs to lose about 10mm in offset.

The wheels work well with the car though, I would just see if there's any machining that can be done with the adaptor and original studs. Studs are easy to replace so you shouldn't be too frightened about shortening them. Just buy some spares first. Of course it's your car, not mine, so do what you want.

Fitment is nice and overall it looks good, albeit 19s are too big for me - I've been tempted to go with 17s. Did you roll the fenders and is there any rubbing up front at lock?

I initially rubbed only on the driver front because of my fat ass, lol, so just adjusted the coilovers to support my 220 lbs of weight lol.

Didn't need to roll fenders or camber.

ER34 GTT Altia 

I want to have such setup: 

18x8.5 ET35 - 235/40R18 
18x9.5 ET22 - 265/35R18

I have no worry for front. 
I'm confused about ET22 rear.
Is anyone ride on 265 at rear with ET22 or less, I don't want to roll the guards.

Wheels: Work VS-XX
F: 18x8.5 +28 r-disc  235/40/18
R: 18x9.5 +32 a-disc 255/40/18

Regarding the fronts:

  • I'm not sure if I needed to get r-disc since there's about 1/2inch 2/3inch gap between the R34 GTT brakes and the wheel.

Fitment:

  • I would say it is almost perfect. The fronts could be a bit more aggressive though.
  • No camber adjustment, just lowered.

Since this is the page where i found myself while searching for wheel fitment, i will add the ones im looking to replace too.

Fenders arent rolled, so in big bumps they touch the tire (tires could be narrower). no any adjustable arms, so the camper is what it is (dont know).

Wheels: 5ZIGEN Fireball

Front: 18x9.5 ET12 - 245/40
Rear: 18x10.5 ET25 - 285/35

Rear: 18x10.5 ET25 - 285/35

So, they simply stick out too far because very wide + very low offset (at the front).

At least it's up nice and high so they shouldn't bang into the car too much.

    • Sorry, just assumed that talk of coloured pads meant EBC red/green/yellow/shit stuff. I don't know the DBA pads, but it's a reasonable bet that they will be OK. DBA make good stuff generally. Those 4000 series rotors I linked to are very good. I may well replace the RDA rotors I have with those when required.
    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
