Gtt Rims Offset

[SHANE666]

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.

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

if you want fat then anything lower then +25 will suit ya =)

+35 & +38 won't fill the guards!! it will give the gay sunken wheel look

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.

[dori34]

^ should look tough

im trying 17x7.5 +22 (f) 17x9 +15® so ill post up pics when i get them fitted...

[SHANE666]

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

[SoFly]

might as well get +29 on the rears also, you can just put a smaller size tyre on if it sticks out abit. ie 235/40/18 on the rears and 225/40/18 on the fronts.

[msports180]

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.

[SHANE666]

[dori34]

hope all goes well lol

[SHANE666]

dori, if you could do that it would be great help!!

I want the rims to fill my gaurds....pics should be wonderfull....ill be waiting!

[dori34]

update: now got 17x8 +17 for the fronts.

definately will have to roll the guards & i need new tyres so just waiting for $$ to come back in..

should be another week or two hopefully.

pics soon shane.cheers

[SHANE666]

too easy dori...

im going to hold back on my rims for a while....

huge paper losses tis week on the stock market.

need to revaluate my financial position this weekend.

[TR34GT-000]

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.
