Different Wheels Size On R35 Gtr !


Recommended Posts

as long as you maintain the same diameter / height front to back you will be ok. ie. the combined height of wheel + tyre needs to be the SAME (or within about 2%) front to back, otherwise VDC will kick in (thinks you are wheel spinning). So yes in theory you can run a different diameter wheel, as long as the tyre size/profile compensates to make the front and back wheel+tyre the same approx height. Hope ths makes sense.

You might want to think about the tyre pressure monitor thing too.

how about the offset, how much different in offset can the R35 run?

A few of us have run some pretty odd offsets, the computers don't really care. Obviously there are other issues which affect every car.

yeh no issues here running larger and wider sizes, in fact the car feels even more planted and comfortable on the road

though i played it safe, and went same size increase all around - so that's 1" wider and 1" taller than stock

i put new oem sensors in my new wheels and the dealer cant get them to pair up. Last resort will be either to buy them from an Aussie dealer and cross my fingers they work, or pull apart my stock wheels and take the sensors out of those - a job for when i cbf, atm im just ignoring the light on the dash

so as long as the diameter the same the offset really doesn't make any issue with the GTR ATTESA system?

Would previous model (R34) be affected if the offset different? I hardly seen the old model running on different offset (maybe I am blind lol)

Correct r35 doesn't care about offsets, some of us have run some pretty stupid offsets, mainly due to limited wheel choice. Equal diameter front vs rear is important however. Must be within 2% or thereabouts. My experience is that anything less than 640mm height has issues too.

Sorry I have NFI about the r34 system.

R34 AWD system doesn't care about offset either but like all GTRs they need as much front grip as possible. more front track gives you some more grip so most run same offset front and rear. there is no point having your wheels stick further out in the rear just cause it looks cool. all it does is make the car handle poorly.

Problem being thanks to the hella flush fitment/stretched tyre brigade you cant even get proper sized & offset rims anymore to suit the tyres you want to run. :rant:

    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂
