Rim help

[Notorious Skyline]

So I’ve got a r34 sedan that I managed to get green stickered, meaning I need to go through government approved wof station for my car to be allowed back on the road

for some reason my car is certed for 19x8 rims.. I need these wheels 

does anyone know what offset will be fine to clear Nissan big brakes? I saw 35et for sale near me, I can’t drive the car to test fit or risk being fined ..

 

I searched heaps online couldn’t find anywhere..

Define "Nissan big brakes". You just mean standard R34 4 pots?

And...it's not even the offset you need to worry about. It's really a detail of how much clearance there is between the caliper and the back of the spoke/face, which is affected more by the design of the spoke than it is by the offset.

If you think about it....take any wheel, say a 19x8 that does fit and clears the caliper. Then add or subtract an inch of wheel on the outside, without changing anything else. You have changed the offset by half an inch, but not changed the clearance situation at all. Same for if you add or subtract an inch from the inside edge.

The way for you to work this out is to take a wheel off the car, grab a straight edge and a ruler or two, and start to measure the distances from the wheel mounting face on the hub to the outer face of the caliper, and the outer diameter (that faces the barrel of the wheel) of the caliper. Armed with these dimensions and any other measurement that grabs your fancy while you are there, you can then go to the seller of the wheels and do the reverse measurements from the wheel's mounting face and see if there will be clearance to the caliper. There really should be. I have 17x8 RPF1s +35 clearing the caliper face by a finger tip. Those wheels do have pretty thin spokes with some curvature.... but then so do most wheels to suit Jap cars.
