OK... So I just got off the phone with HRE. The original sizes and offsets I was suggested was; 19x9.5 +32 (265/30) & 19x11 +34 (305/30). I questioned this and was told they will fit. Well I got in touch with Lon at HRE via another forum. Told him the sizes/offsets and said they don't sound aggressive enough. So we shot e-mails back-and-forth. Anyhow... New offsets for my HRE P43SC are; 19x9.5 +20 (255or 265/30) & 19x11 +25 (305/30).
Then as far as tires go, unless your making serious HP , don't run more than a 30mm stagger in width. So with a 305 rear , run no less than a 275 up front. Even better, run a 285 up front.
Running a 10 to 30 mm difference in stagger with the same aspect ratio (example 275/30-19 and 305/30-19) will keep all electronics completely happy.

If your having HRE make you wheels, order a 10 +25 for the front. I would actually order a 10 front and 11 rear in +25 for both.

OEM rear camber specs are -1.1 to -2.1 , -1.75 is actually very average for these cars. With high HP i would shoot for the lower side of the range -1.0 would be ideal.

I already have the rims. Volk GT-S 9.5/10.5 + 17/18. I'm not even close to rubbing with my 275/35's currently. Will 20mm make that much of a diffence (and going down to 30's)? The guy at the tire shop doesn't seem to think it will be a problem. I just don't want to find out the hard way.

There's no reason to be afraid of rolling your rear fenders. The Z has a huge lip on the fender and a roll gives a lot of extra room. Why don't you want to roll the fenders?

Question for the experts: ill be running an 18x9.5 +15 up front. Will a 275/35 be too tight of a fit with rolled fenders? I have zero intention to tuck tire or anything of that sort.
If 275 is too close of a call, I can just play it safe and do 265.

+18 is quite aggressive for fat tires. The 295/30 will fit fine but you will need a roll or more camber if you are planning to tuck a little tire. Ideally you should roll the fenders and adjust camber to get it as flush as you would like.

Looks great!!! What size did you calculate mine to be at? 295/30 or 305/30? I'm getting excited! What mods have you done? Are you rolled/lowered/changed camber? Also, what do you have on the front?

I just calculated the actual wheel/offset itself. Are you lowered?
I know I am going to have to roll my fenders for sure and possibly run just a TAD more camber than that picture when I find time to put my springs on.
I would assume around the same for your setup but a little less camber.
That picture is 305/30.
Edit: here is a little better picture to show clearance.

mounted the 305/35/19s from my rear to the front (370z 19 rears) with no issues (no spacer +33) I didnt drive it, just a quick test fit. Now running a 275/35/19 on the 10 inch wheel for the front. 305/35/19 on a 10 inch wheel for the back.
So the second set of 370z rims was ordered to get 19x10s on all fours (no spacers front, 20 mil rear) (See attached pic) Before and After RIP Rice Version. Ill miss you! LOL Rice version had 20x9.5+13F (255-30) 21x10.5+17R (295-25)
sold the 4 19x9.5 to G37X sedan owner
Next sending the 19x10s off to get widened to 19x12 or 12.5 (havent decided yet) next week.
345/30/ Nitto Invo 19s are in route also.
Cant wait to claim 300s on all fours for my G35. Simply for bragging rights and to launch this 22 supercharged PSI beast to aircraft speeds in the 1/4 on street tires!
Stay tuned!

I've got 255's in front, my wheels were discontinued so I had to settle for a smaller one.
I would probably go with a 275 on your wheels or even maybe a 285 but I think that is the limit.
