what is the off set for the new Z?
 

hi guys,
im new to this, i was wondering what is the right off set for the new Z.
im planning to get this car and start to doing some research on it
thanks

Here you go!

Those are the stock specifications. Do some measurements if you can access a 370Z and go from there.

Hope that helped. :tup:

that's helped alot! however, it says "you do not have permission to access this page".
so can you guys copy the picture and post one in here please? thanks alot!

Yeah. I'll do it. Give me a few minutes.

yes, sorry the e-mail was in my trash e-mail, that's why i didn't know. thanks alot! and thanks for everyone, thats help alot.

Hopefully this info will help. The numbers to follow all should work.

For a 9.5 width front wheel offsets 30-47 should work mid to low 40s being ideal IMO

For a 10.5 width rear wheel offsets 15-24 should work 24 being the least aggressive but probably what I'll use.

Wheel Offset Calculator

^This is a handly little link I came accross and what I used in conjunction with common Volk offsets to draw these conclusions.

Just looking at the numbers you provided above makes me drool. Low offset, high width. :excited:

Keep in mind that these offsets are just a guide. Even when using one of these offsets a specific wheel may have caliper clearance problems. Most distributors allow you to test fit and return as long as no tires are mounted. Until 370Z owners have test fit wheels this would be prudent.

Too bad no 9.5 +22 on the fronts.

thanks guys, but will it be ok to use 8.5+36 for the front and 9.5+37 for the rear? because i have a set of volk for this specs and wondering which spacer should i add to it

^The front would be fine but the rear would be sunk. I'd recommend a 15-30mm spacer on the rear. To be honest, I'm pretty dissapointed with the factory wheel specs and the big difference in wheel offset between the front and rear

thanks alot!, but do they ever have 30mm spacer? is it safe enough to use 30mm this wide?

bolt-on and hubcentric is what you want, plus some threadlock for extra measure.

sorry, im not good at these term, can you give me some example for what is it? thanks alot

If you haven't already, go check out this thread:

http://www.the370z.com/wheels-tires/...s-stock-z.html

There's a post in there somewhere saying that if you're going to stick with the stock sports package wheels, you're going to need to use spacers that require knocking your old studs out and putting in some extended studs. It's a good read. Go check it out!

oh, thanks! but i read it already:tiphat:

How would +22mm offsets with a +30mm spacer on a 19x8.5" wheel look on the 370Z?

So what part are you having trouble understanding? Bolt-on and hubcentric? A bolt-on spacer is one that actually bolts onto your existing hub via the stock wheel studs, like the one I tried using in the Wheel Spacers thread. It includes its own wheels studs, which is what you mount your wheels onto. You can get spacers that are just a ring that slips over top of your existing wheel studs, and you don't actually bolt them down to anything. So that's what's meant by bolt-on. As for hubcentric, some spacers (again, like the ones I tried) come with a centering ring so that it actually snaps into place over the wheel spindle with no play. Look closely at the pic below. Look at the center of the spacers -- there are actually centering rings in place that make the spacers fit with the spindle perfectly centered. And of course, you can see that these have their own wheel studs. The stock wheel studs would come through the holes, which you'd then bolt down.

Now take a look at these el cheapo spacers, for contrast.

http://www.streetperformance.com/ART...2375_large.jpg

These spacers are neither bolt-on nor hubcentric. You just place them over your wheel hub with nothing bolting them in place, and there are no centering rings to make sure they sit perfectly centered.

understand now thank you so much, but which type are better and stronger? in your thread, you said hubcentric will not fit on stock wheels right? so we need to get the Bolt-on for no choice?
P.S. sorry for my misunderstanding, i have poor english...
thanks alot

No, the hubcentric part has nothing to do with not fitting the stock wheels. It's the bolt-on part that causes issues. You need to get something like the H&R DRS series spacers. This is mentioned in the other thread already. You will need to remove the existing wheel studs and replace them with the extended studs.

I posted this question in a different thread, perhaps it is best suited for a reply here.

I am still a tad confused with the 370 offsets. Would it be possible to run 19x9F +25 tire 255/35 and 19x10R +25 tire 285/35 without any issues (this would be for the sports package)

You will have issues. It doesn't make sense to run the same offsets on both front and rear. Look at the stock offsets already provided on page 1 of this thread (post #4). The front offset is +47, and the rear is +30. Using a front wheel with an offset of +25 means that you'd be pushing the fronts out by 22 mm! They'd stick out and give you what I call the 'skateboard effect'. Now, +25 would work just fine for the rear, because you'd only be pushing it out by 5mm. If anything, I'd be inclined to go for a +20 offset on the rear to push the wheels out by 10mm.

As for the tire sizes, the important thing is to try to keep the overall diameter of the tires as constant as possible, because your speedometer is calibrated based on the tires' OD. You can look up the OD of the stock tires at Bridgestone's website. Here's a direct link. Sizes and Specifications

Now what you need to do is look up those tire sizes you want at the website of the manufacturer (you didn't specify the make) and compare the OD. If they're reasonably close, they'll work. If not, then no.

Let's just say, as a hypothetical, that you intend to use the exact same brand/make of tire, just different sizes. Well, the chart shows that the stock rears (275/35-19) have an OD of 26.5. On that same table, it shows that the OD of 285/35-19 is . . . it doesn't even show such a size on the table. So you can't even get that size, at least not with Bridgestone RE050s. But you get the idea. Assuming that this size does exist with some other manufacturer, you'll want to pull up the spec table and compare the OD to make sure you're not changing it too much.

OR...you can calculate it the old fashioned way. 275/35 means that the sidewall height is 35% of the 275mm width, which is 96.25 mm. 285/35 works out to 99.75 mm. So the sidewall will be 3.5mm higher. That's negligible, IMO. Repeat the same procedure for the fronts.

SemTex,
Thanks for the reply.

I can see this thread turning into 150 page clublexus style "will this fit?" thread........simple math and reference to others who did similiar fitments will prevent the laziness that is the "will this fit" question. *steps off soapbox*
