F14 fitment

speedworks

I don't understand why you wouldn't order the right offsets from Forgestar and forgo any spacers? If you can get the right offsets from the beginning, that is the best. With this setup you have moved your fronts out 23mm and only 10mm for the rear. Why not move the rears out 20-23 to match the fronts, so that would make the rear an offset of 10-7?

NISMOFO

My guess is that he wants to use stock tires with these widths?

speedworks

Offsets don't affect widths of the wheel. He can go with his stock sizes with the 9 inch wheel, and choose an offset that doesn't interfere with the fender.

You'll need a 10 or 15 mm spacer for the rear with the specs you ordered. I would go with 15 mm since you'll be lowered.

I want to use stock tires but i got the lowest offset that they had for 10 inch which is +20. I did not want to use spacers but its the only choice

NISMOFO

You beat me to it :-) I was going to mention +20 is the lowest.

And the truth is that forgestar does not make awesome offsets. They are limited to what they can do since this is a one piece wheel.

Personally I'd love my wheels about another 5mm front and 10mm rear farther out. The most I can push the rears out is 1mm with their specs. I have talked with Peter at forgestar about this. He says there is a 19x12 F14 in the works....but a +42 offset I believe which will suck them in farther.

oleg

what the widest size tires would you be able to run on the 12 width once than, and would that even fit on the Z

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?

Nitex

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.

NISMOFO

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.

oleg

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

NISMOFO

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.

oleg

wouldn't that big of a difference on wheel width cause a car to have huge under steer, because thats why initially i was planning of just going with 19X10 all around from forgestar but i didn't see anyone do that before so i didn't want to risk it

mine shipped yesterday!!!!!!
