R34 GTT stock wheel size? Fit R32?

I've tried to measure the offset of my stock R32 rims. It's a bit hard to be sure on the car but they seem to have 40mm offset.

If my 6.5" R32 rims are 40mm offset and Gtt rims are 7" would 35mm be near the ideal offset?

Does anyone know what the actual Gtt offset is?

They are 7.5 wide not 7.

Stock tyre size is 225/45/17.

Offset is roughly 35 front, 38 rear. - May want to double check that

Are you sure the offset is different front to back?

I bought a set of GTT rims today and they are all the same. The offset seems to be 39 or 40mm. It's a bit hard to measure to the mm with the tyres on.

From outside to outside the rims are 22mm wider than my 6.5" R32 rims so yeah, they are probably 7.5".

Anyway they look like a 100% legal upgrade for the R32 :)

Yes i was wrong about the offset. That was the offsets for 18x8 and 18x9 to fit my car. Nfi why i remembered at the time that they were stock offsets.

But yes they are most definitely 7.5 wide. Tyre placards etc state it.

I tried fitting them today.

Julzz was right, the fronts don't quite clear the TypeM caliper.

A 3mm spacer would fix it but aren't these illegal?

They only just touch as you fully tighten the wheel nuts.

Actually there would be plenty of thickness in the caliper to shave about 2mm off the edge that touches the wheel.

Is this too bodge?

majority of people shave off the Nissan wording on the caliper, this usually gives enough clearance for the rims.

id prefer to do that instead of spacers, as spacers are illegal.

Mine didnt touch the nissan logo, it was far from it. It was hitting the whole edge of the caliper when the tyre was rotated.

I have 34gtt rims on my 32gtst, they are 7.5" wide. I'm running 225s on the front and 245s on the back.

Initially had to run a 3mm spacer on the front as the rims bound up on the brakes, when I changed to 33gtst brakes this problem went away and I didn't need the 3mm spacer (there is barely 1mm of clearance though).

I have fitted r34 gtt rims onto a r33 gtst with no problems at all.. No need for spacers etc

However it might be ideal putting 3mm spacers on.

offsets are 38 (so i have read on these forums in the past threads)

I dont see why it wont fit a r32.

They got smaller brakes right? compared to 33s? if so then will fit perfect

I have seen pics of 32s with 34 gtt rims :P

bubba- WOW you got 245s on a 7.5inch width rim?? how? lol

thought 235s would be the most..

Yup same here.

however, its like a mm off from touching.

Rims still rotate freely!!

      And if you want more power, more reliably, and cheaper, go get the Aussie RB... The 4L Barra and put that in instead.

      No cats will keep discolouring the rear bar. Sends white paint a weird yellow stain. Cut and polish normally gets it out, but you'll be doing that every fortnight I found.

      Both heads will be equally reliable or unreliable depending on what you do to them.  Stock the RB26 head will flow more. You have access to the stock intake ITB manifold on the RB26 cheaply which flows really well(1000hp+).   Arguably more aftermarket support for RB26, though in Aus we love our RB30 SOHC heads too.    The only downsides to the RB26 head is if you have a VL commodore and want to keep the SOHC look.  Where you may have an issue is drilling out the rb30 block for the bigger head studs but if you are building a big power motor you'd probably put bigger studs on the SOHC head too.  This is just about finding a good machine shop, sometimes easier said than done.  RB30 head worked can make big power just like a Rb26 head, so really it actually more comes down to what your preference is for your car.  People now even making billet versions of both.

      2630s work perfectly well. There is something to be said for just using the 30 head, as it saves all the pain of the conversion, still makes tons of power, still sounds cool, etc etc. 2630 will obviously make more power again, but the differences are not stupidly big. It really depends on whether you're racing for sheep stations or not. If it's dead serious, then it's a 26 head. If it's just for fun, it could go either way. But the 26 head and the effort to get it set up, etc etc, is part of the fun.

      I've been building a 26/30 for a few years now. I've had the head built with all the good stuff. I had a 32 gtr but blew it up and yes its all going into a vl but im looking for some advice from some RB nuts on pros and cons on putting a 26 head on a 30 bottom end is it worth it Works are as follows Head -Extensive porting 1mm oversized supertech valves Supertech double springs Supertech valve guides Supertech titanium retainers Tomei solid lifters Tomei 270 x 10.25 cams Head drain Bottom end series 2 rb30 block Cp ceramic coated pistons Eagle rods Romac balancer Oil restrictions  O ringed blah blah spent a fortune And will get a girdle because the 30s arent used to handling that much rpm Nitto billet oil pump Hypertune plenum 6boost mani Refurbed astra pump thats the cover for it in the boot I did have a precision 6262 but sold it because drag car life. Currently building the ass end full 4 link floater rear end with a 2 speed  But the dilemma i have is my mate rekens I should just stick with the 30 head for reliability. Has any one had any issues with mounting the 26 head ie compression blowing gaskets etc. Just looking for some advice from people who have gone down this route. Here's some photos. Blew the oil pump in the gtr and decided to rip the motor out at the time and do a full build only to find it had been a repairable write off so went down this path.
