I am not an expert wheel fitter, but it looks like you'll have no worries.  I measure about 21mm gap from rim to that suspension arm.

Wow, thank you so much for the effort!! ?

Just wanted to say a big thanks to @ob1, @r34.bryan & @Gazzaa

Ended up going with some Rota's. Really happy with the result. Thanks to your kind replies and info they fit perfectly. No scrubbing or guard rolling and car is lowered. Looks 100% better.

For any other budding R34 Gtt drivers out there, this is what I went with.

F: 18 x 8.5 +30 - 235/40R18

R: 18 x 9.5 +35 - 255/35R18

Damn, fit looks perfect!

R34 with Rota D2-EX in 18x9.5+18 all round.

tyres - 235/45 all round.

Fit perfect. Has BC BR coilovers set to fairly stiff. Slight rubbing on front inner plastic guard at full lock. And only rubs on the rear slightly if I hit a huge dip in the road at speed. Will probably give the rear guards a slight roll and lower more in the back.

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!

Supposedly a 18x9.5 +22 will be flush fitment. I just can’t seem to figure out whether 255/35 or 235/40 is the move on tyres.

I’m hoping someone can enlighten me on that.

I'm figuring out my setup at the moment - alignment isn't for another 5 weeks.

For the front I'm running TE37s in 18x9.5 +22. Camber arms are Cusco and they're set at the max negative setting, which is -2.2 according to the manual, but are likely around -3 with the drop. 

Front tires are 235/40 Hankook V12 Evo 2s which I'm using for getting the sizes right. 

Arches are rolled flat and pulled very slightly. As you can see, there was probably no need to do this.

I'm contemplating getting 255/35s up front and dialing the camber back to -1.35 (as per the manual) but it will be tight. I am currently hitting the fender liners at full lock.

Sorry the pic is portrait, I took this to send on my phone.

 

[GoHashiriya]

Dialled the front camber back to 1.35 degrees (as per the cusco manual), it's probably around 2.5 degrees with the drop. Rear camber is unknown at the moment. 

Wheels: TE37 SL 9.5J, +22/ 10J +10

Tires: Hankook V12 Ventus Evo2 235/40/18 front and 255/40/18 rear

Fenders rolled flat. 

[GoHashiriya]

Whoops, that's actually 10J +20 for the rear.

Thankyou for that last update, I went measuring based off your previous post (cause it looks great) and I was thinking the differential between the fronts and rears was a bit weird for it to fit so nicely.

Looks awesome dude

No worries, cheers for the appreciation.

I should probably note that the rears are hitting the bumper tabs under high compression - happened a few times on the highway. I think the toe is out quite a bit (toe in) - just from eyeballing it. The 255/40s were the fronts off my Z, they're not ideal but they fill the gap well. I'm undecided of where to go from here, possibly 265/35 rear and 255/35 front when i upgrade (hankook V12s are sh*te).

The fronts are scrubbing the liners on full lock and again under compression. I'm gonna heat them up and try to push them back, possibly try and push the fronts up with the arch roller, then I've got some weather stripping to seal the newly-formed gap between the liner and the fender.

Did anyone manage to fit a 18 inch 275 in the back without stretching the tyre? Chasing the Performance here, so a meaty tyre is desired.

As i'm reading 255s are scrubbing the liners in the front, anyone fitted 245s? Since any visible scrubbing on the liners will get your car immediately impounded here and they check that in EVERY police control 😕

[Kinkstaah]

You can put huge tyres on the back with custom wheels, there's a ton of room on the inside of the R34 rear to pick up some seriously large rubber. I think I measured I had something like 40mm extra room to play with when I stuck my head under there and measured. (and I have 275's back there already)

Would need a rim with a custom offset to make use of this though.

Fronts you can run 255 without scrubbing. I run 265's up the front (265/35/18) and didn't have any scrubbing until I took it to the race track. Even then if I got creative with a heat gun I could have moulded it further away/clippied it closer to the body if I had've cared a great deal.

(I care a little deal)

Funny enough if you have wide enough guards a 285/30/18 (or 295!) will avoid liners better than a 275/35/18. But that's future talk.

Is there actually no one that uses the performance of their Cars? Barely getting any information out of this thread... Seems like people love putting 235 tyres on a 18x9.5 Rim... (My GFs Mini Cooper has bigger tyres btw.)

Trying to figure out which size and offset i should order my Volk Ce28n in is a nightmare, since i currently only got 255 in the back and they can't hold the power on a mountain road. Should fit beefy Toyo R888R but can't have any rubbing or scrubbing under any circumstances, full lock steering in a circle 5x at 40 km/h will be tested, else the Car gets impounded.

[Ben C34]

Just limit full lock by spacers in the rack. Problem solved.

[r34.bryan]

Got my new wheels and tires!

Wheels: Work Emotion ZR10 (front: 18x8.5J +32 rear: 18x9.5J +30)

Tires: Toyo Proxes R888R (front: 245/40 rear: 265/35)

Car: 1998 R34 GT-T coupe with stock fenders, lowered on coilovers.

Camber: front: -2.2° rear: -2.5° I will reduce camber on the rear to about -1° or -1.5° soon.

I hope this can help someone. Fitment is perfect I would say.

Thanks to everyone on this thread for your info, experiences and helping me choose the right sizes.

Keep on topic or you get a holiday.

I recently just changed the tire setup on my car. As mentioned, the previous setup was for trial purposes and I really wasn't a fan. The rear profile was just too large and it kept clipping the bumper tabs.

I'm now running Accelera 651 Sports in 255/35 18 front and 265/35 18 rear. It's clipping the liner in the front under lock but as @Kinkstaah mentioned, you can push them back with a heat gun.

Wheel specs are the same: Volk TE37SL 9.5 +22 and 10 +20 rear. If I were buying these again (I orginally bought them for my Z33), I would likely get 9.5 +22 all round.

Camber is -3 front, -2.4 rear.

I may have fixed my wheel problem.  I purchased URAS superwide Aero.  

[Drkirby]

Hey guys anyone tried fitting 

Rays TE37 18x10+45 

[Kinkstaah]

The rears may actually fit, barely, but won't be in line with the guards.

The fronts will absolutely smash about 25mm into your front struts 😛
