Rota GTR-D on wide s14 wheel offset help!

[Gti-james]

I'm part way through my S14.5 project and am now looking to get wheels this weekend so I can fit my rear arches.
Ive decided on getting GTR-D but have been convinced to go for 18x12 on the rear as i love the dish and 18x9.5 front.
I'm just really stuck on offsets as I want the wheels to sit with the arch and not stick out.
I've got 50mm SRB power Rear arches and S14.5 20mm front wings so am trying to find out what offset I need and if I'll need spacers?

think they only do the 12j in an et0 so dont think youll have any choice on the reat tbh lol. 9.5 will be too skinny behind a 20mm front wing so id probs go 10et25 ish on front and just see how the rears fit and go from there. i run 9.5 et25 on the front of mine on a standard wing with a 5mm spacer and it hardly pokes at all..

Think you can get ET20 in the 12's aswell

12Js only come in ET20 - the ET0 was not popular so we're not doing them any more.

18x9.5 ET12 or 18x10 ET12 should be fine on the first if you want full size tyres, if you'd like stretch then you might want to space them a bit for the correct 'stance' that is currently cool

[Gti-james]

So if I get Et20 12j rears, how much do they stick out on a standard rear arch

[clive]

a **** load.

[Gti-james]

I surpose there will be less dish on Et20 than Et0 and I'll need spacers no matter what offset I get to fit 50mm arches?

I have a similar setup on my 14.5

Rear 18x12j et20 with a 5mm spacer to clear coilover, standard arches rolled (alot) and flared slightly







FRONT- 18 x 9.5j et12 with no spacer and 25mm ( i think ) s14.5 wings





Hope that helps mate.

The dish is exactly the same on all 12s, ET20 and ET0 - it's only the very centre that changes - so no need to worry there

Hey guys slight thread bump here but I have a few questions,
1) what is the finish on the GTR-ds on the yellow car above?
2) what sort of dish do the 18x10 come with compared to a 9.5 for example?
3) do you have any decent fitted pics of gtrds in steel grey on anything?

[Evilchap]

That looks like Bronze in the picture
18x10 and 18x9.5 have a very similar dish
Steelgrey is a very new finish for this wheel, I am afraid we have no pictures fitted right now

[japdrifter]

Really!? That's the shiniest and silvery looking bronze I've ever seen mate

So what we talking on dish difference? 1/2 inch more on the 10?
