called forgestar today, they said:
19x9 +25 up front
19x11 +28 in the back

I trust what they say, but you guys warned of the +23 up front... +25 isn't much off of that! I would *assume* +30 would be a safer offset to go with, correct?

Seriously? whats with all the +28+43? Thats not going to be flush at all, again i do not feel im flush at all with 19x9F 19x11R +24 all around.

And when i ordered my wheels i was told i can get any offset i choose (ideally +20F +15R) However they would not guarantee fitment and in the case the wheels did not fit, i could not return them.

Just fyi, im running 275s upfront, and 305s in the rear.

I think our specs are flush on a stock height car but not a dropped car. If I had a front camber kit that would bring it out quite a bit. I have strongly considered 5 front /10 rear spacers before, but I'd rather not. Forgestar makes great offsets for stock height cars, just not lowered cars.

12" should fit fine. I wanted to go 12 but don't really want the CF5 model. Thought about 18" but tire diameters are too small, but offsets offered are better.

325/30 was the size I would probably run, although Porsche has put a 305/30 on 12" wheels for the GT3 and GT3 RS in the past....I wouldn't try it with a hankook though.

At that point I'm guessing there wouldn't be any wheel spin off the line from a 370z with out any engine mods?

Yeah and the biggest downside is the extra weight. 12" will fit fine. O had thought about doing a 8.5/12 combo like a GT3. Forgestar just doesn't make good offsets in the CF5 and soon to be F14 19x12" with a +42. If the rear suspension was a little wider on our cars we would not have this issue, but what we have is a wider car than a 350z with basically the same rear suspension...so we have to run lower offsets...which means heavier wheels as far as one piece wheels go.
