Im currently lowered on H&R springs. Does anyone know if the fitment will be somewhat okay? I realistically just want the fitment to be flush and close most if not all of the gap without any slight rubbing. My friend is running the same setup so i just went with somewhat the same specs. But he’s way lower than me (bc’s) Any help/info would be good. If I need to switch it up i will try to swap the tires out for something else. I also don’t want to go crazy wide in the rear, for me I personally don’t think theres a point of running 305s considering i daily the car. Just wanted something to close the rear wheel gap but also be sort of meaty. And the front i could care less just want something to match so the fitment looks good.

Your post is just hard to read so it’s hard to give advice. You want an opinion and at the end of the day, there’s no correct answer to your question. Especially when you’re putting a personal (pretty controversial) opinion into the post. “Personally I don’t think there’s a point of running 305s considering I daily the car.”
I daily mine on 325s rear and 295/ front. How do we know what your “somewhat ok” means?
There’s over 3000 posts in here. Just go look at pictures and make your own judgment.

Or just...look at his friends car?

305's are not meaty on the rear.

New to this wheel game, some help will be appreciated. I did try to do as much research before posting here, so here are my unanswered questions.

Currently I am looking to get some Yokohama Advans RG 3, I am also looking for some good tires (all seasons) any recommendations would be great.
These are the following rims and tire sizes I am looking at.. Please correct me if I am wrong or if I am running something dangerously crazy. Wont be for track use (maybe once or twice a year but never tracked before), reason for all season tires is that I live in Canada. We always have dramatic weather no matter what, recently (a few days ago) we experienced snow in the middle of May. However, This will be mostly ridden for the spring-fall seasons.
Fronts : 19x9.0 114.3 / +25mm Tires : 255/45R19 OR 245/45R19
Rears : 19x10.5 114.3 / +25mm Tires: 295/45R19 OR (If I can find any) 305/45R19 tires

They don't seem to make a +15mm offset for the fronts. They do make a 19x10.5 with a 15mm offset, will that be able to workout? Or will it there be potential rubbing at that size (front wheels)? I am looking for a flush or a bit poking out look (not sure what the terminology is). I will be replacing out my coil-overs to the KW Variant 3 or 2, I am also not going for a "slammed" out look. Will it even fit? I am trying to find the stock offset for the 370z Sport rims, can't seem to find them with any luck. Not sure what minimum offset I should be looking at since I have the big Nissan Sport brakes. I am extremely lost on the offset part.

I understand that ideally you want to purchase both wheels and coil-overs at the same time, however I am not strapped of cash... My online research suggest that I should go coil-overs first then the wheels vice versa.... Some forums says that it doesn't matter. What should I be doing first? Currently I am running the stock suspensions and wheels from the 18" 370z Sport.

I personally would purchase coilovers and get your suspension in order before wheels. You will avoid the monster truck look and also be able to figure out sizing and how things will look especially if going wider than stock.

Thanks, that helped a lot. I now understand offset more clearly. Going to be going with a +15 mm offset on the rears, and a +45 mm on the fronts.

Good idea, the sport OEM tires and wheels doesn't look too bad. If it was lower it wouldn't look too bad. Will I need an alignment if I were to get coil-overs? Will not be purchasing the tires and rims for at least another 6 months. I mean I can just not install them and wait till I get the tires, but who wants to do that?

255/45-19 is 28.1" tall. 295/45-19 is 29.5" tall. That's 5% difference. Your dash is going to light up. You have to stay under 3% difference. A 295/40-19 on the rear will be great. It's 28.3" tall. That's only a .8% difference. 245/45-19 with a 295/40-19 is cutting it close to the 3%. It's 2.3%.

Yes, if you add coil-overs (or change other suspension parts), you'll want to get an alignment.

And any time you change ride height too.

The Advan RG3 is not really designed for our cars; the sizes just aren’t there. A +45 front is terrible

Check out the Advan R6, a newer wheel that is basically an evolution of the style with a lip and available in better sizes.

The reason for coilovers, wheels AND SUSPENSION ARMS is to set height and alignment one time.

20x10.5 +24 with a 245/35
20x12 +20 with 285/30

If you want a meaty look, 285/30 front and 325/25 rear, but those sizes are probably gonna be for summer and track tires


If you read my thread again carefully you will see that offset DOES NOT determine brake clearance. Individual spoke design does.
The R6 will clear GTR brakes so they will clear ours easily

Hey thanks for helping me out, I just finished reading your post and it very helpful thanks a lot! Yeah, I spent the whole day trying to learn about suspension and wheel-set ups. So I think I know more? ish?

I really LOVE the look the RG 3s, It's such a shame that they aren't really made for our Zs.... I'm honestly determined to get the RG 3s in. Not a fan of the look on those R6, I think that's waay to big and funky for my liking. I am also pretty sure that these can fit the Nissan Sport brakes, I've seen many 350z running RG 3s with those big wilwood or brembo kits.

Currently I am thinking of doing the following.
Fronts: 19x9 + 25mm (19x10.5 + 25mm) w/ 245/45-19 Tires
Rears: 19x10.5 + 15mm w/ 295/40-19 Tires

Not sure if an extra inch in the front will cause it to get wheel-bite, if so I guess I'll try to roll out the fenders. Or just go with the lesser 19x9 + 25mm.

I thought about going the squared route (19x10.5 + 25mm) but that would require some spacers in the rears. Not sure if I am comfortable with running 10-15mm spacers.... Also probably isn't a great Idea.

245/45-19 on the fronts, with a 295/40-19 on the rear it is!

Hi guys,
Looking to get some new wheels and needing some help.
Can I do:
Rear - Work CR Ultimate (Kiwami) Wheel - 19x11 / 5x114.3 / +18mm Offset (275/30/19)
Front - Work CR Ultimate (Kiwami) Wheel - 19x9.5 / 5x114.3 / +25mm Offset (245/35/19)
Both are deep concave style. Will these clear the brakes and have a flush look?

Unsure about clearing the brakes with those wheels; but the offsets are doable.....tires are awl fully small
