This may have been covered before, but I couldn't establish for certain an ideal offset for the r34 gtt

Ive got a r34 gt25..

Im looking to buy DTM Rush in matte black from access autoworks off the forum...18 inch, 8.5 fronts and 9.5 rears

What offsets would suit?

Ive asked around and most people say 35s or 38s, but since I am getting two different widths for fronts and rears, what should my offsets be?

I want to acheive something that looks PHAT

Cheers.

Shane

I'm fairly biased and like drift style low offsets, i think those wheels come in +25... that would be hot, just sit out the guards a little. or even +25 at the rear and +30 at the front. Or something like that. +35 or +38 is fairly standard would sit in the guards about the same as standard gtt wheels. Hope that helps a little.

You gotta work out what will fit.

Think of it this way, stock GTT rim is 7.5" wide with an offset of +40, this sits the outside of the rim 55mm out from the hub. An 8.5" rim with +40 will sit the wheel 68mm out from the hub (13mm or roughly 1/2").

7.5"x25.4(mm)=190.5/2=95.25-40(offset)=55.25mm from hub to outside of rim

8.5"x25.4(mm)=215.9/2=107.95-40(offset)=67.95mm from hub to outside of rim

Extreme example: 10" rim +20 offset

10"x25.4(mm)=254/2=127-20=107mm from hub to outside of rim

You can use that to figure out pretty much where a different sized/offset rim would sit compared to what you currently have :P

WOW +25 it might be then.

i want to get rid of my current sunken in look.

those rims on the above white gtt is what im getting for my silver gt25...red turbo brakes too :)

what you guys think?

will probably get +25 offsets, 8.5 inch fronts and 9.5 inch rears.

okay guys,

might put my order in this week

18x8.5 +29 fronts

18x9.5 +35 rears

or should I go for +29s at the rears too? thought the wider wheels might fill the guards...

what do you guys think?

Not too sure...havnt seen many more pics of +25 offsets on a 34

Go the +29's at the back to. Will need to run an undersize tyre though. Alot of wheel fitment also comes down to the ride height due to camber change and i think people forget this. I put R34 GTR rims which are 18x9+30 on my wifes 34gtt 4 door and the front the rim lip sat dead level with the guard lip at slightly lowerd and the rear they sat way in. On my old R34 Gtt sedan which was dumped i had 17x9 + 30 and needed a 20mm spacer to bring it out because of the camber and at the rear had 17x9.5 +15 and the rim lip sat 15mm out of the guard. So a 9.5 +29 should with a decent lower and some negative camber have the rim lip level with the guard. The front go for sure the 225 and be aware that if you are running it low the tyre will grab the inner gaurd liner at its taller then the stock tyre.

In all honesty it looks phat having the rim out of the guard and a stretched tyre but for daily use go it sitting level with the gaurd lip.

The pic of the car when its lowered is with the 20mm spacer and the pic of it at slightly lower then standard is without. You can see the diference ride height plays.

Then the black skyline is my wifes with the 34 gtr rims on it.

Yo Shane,

I thought that you would need a +35 just to clear your brakes mate.

Every time I get my ass into a wheel place for some pricing...............it's.................oh no mate, those wheels won't fit, you need a +35 offset. The wheels on the white GTT are awesome. For me, I'd settle for a set of Drifteks any day. They're cheaper! LOL

Hope all is well.

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
