You should be ok with that much negative camber on a 27" wheel...it will lean in roughly 10mm per degree negative from 0 & same going positive.
my base 11' is stock & has -1.0,,,treadwear even across; but i don't track it.
So i couldn't use the +20 9.5's,,,would be closer to +30 for me.
Plan to run -1.0 in rear w/325's on 11",,,so that's gonna be close to +25 or a tad more.

thanks man. you are always johny on the spot with responses.

i am going to go ahead and back off to +25. it makes me feel better and like i will have more flex the cambers i can run.

i was doing some trig and crunching numbers on a 27" tire face. i got about 12mm per degree of camber.

worse comes to worse i can always throw a 3 or 5mm spacer on there.

you think it´s a mistake to back off to +25?

Look up "Rusty's " ride; i know he's on the [official] 370z fitment guide....he's running 275/35/19's on 9.5+25's & has -2 camber... Looks like he could run less if he wanted.
If you go over aggressive; you could be screwed - spacers are always an option.

i am gonna back off to the +25. i talked to jason at getyourwheels and he agrees it´s a safer bet.

thanks again. next post will be photos of the wheels on the car. no more questions!

Yeah, I could run less if I only streeted (-1) and still look good. ;) I'm at -2 for track now.

Getting new rubber soon :). This is my daily driver would 265/35 F 285/35 R mess with the handling and turning at all. Been looking around a lot of people say to make the front a little bigger than the front. Thanks for the help.

Pending on the brand; you seem to be just under the 3% maximum diameter difference.
(That's the percentage difference I was once told/ that wouldn't screw with abs/traction control) other knowledgeable members will chime in on this one.
I've just always heard 3% max.

I will be going with Michelin PSS. Thank you for that good piece of info about the 3% difference.

Both of the Diameter variance according to the Tire size cal if I did it right :). Both are under 3% which is better so as to not to mess with the ride ability. Positive or Negative. If anyone can chime in.

265/35R 19 285/30R 19 shows a -2.17% Diameter Variance.

265/35R 19 285/30R 19 shows a +2.10% Diameter Variance.

:icon17: Look at what you typed. You got the same sizes down twice.

Looking at Tirerack. Mich doesn't make a 285/30-19. They make a 285/35-19, 26.9". and a 285/40-19, 28". So looking at what you want. A 265/35-19 is 26.3" and the 285/35-19 is 26.9". That's only .6" difference. You're go to go. :tup:

I run 265/35 and 285/35, no issue with ABS and TCS

Guys, anybody running 325 in the rear? I have the forgestar cf10. Fronts are 10" wide 28 offset sitting on 275/35/19 and the rears are 11" offset 18sitting on 305/35/19. I wanted to go 325 in the back (I will be ordering 12" rims for rear). Any rubbing issues? Car is lowered on swifts? Thanks guys!

I ran a 325/30-19 PSS on a 19x12 +28 Forgeline rims for awhile. Stock height Nismo. No issues. Now I'm running 345/30-19 PSS on the same rims with a little bit of poke.

Do you think there will be rubbing or issues with 325 lowered on swifts? 345 is just insane dude! Lol

Sent from my Nexus 6P using Tapatalk

You should be good. I was running 345's with H and R springs. Im going too see if 355's will work next. My rims just hit the house today, gonna test fit them this weekend.

Thanks for the information guys. Now I just need to figure out the specs so it doesn't stick out. 325/30/19 28 offset. How did it sit rusty?

1st pic. 325's. 2nd pic. 345's. :D

Wow how the 345 fills up all the gaps, looks incredible dude, stock springs you said? And what's are the offsets?

Sent from my Nexus 6P using Tapatalk

Front, 275/35-19 on 19x9.5, +25. Rear, 325/30-19 or 345/30-19 on 19x12, +28. :D

Anyone know what offset I need if I want to run 18x9.5 in the rear? The wheel I am looking at comes in +15, +22 and +38.

I think I need the +15 but then what size spacer would I need?

If anything the +15. But will still be a bit weak for the rear. Typically you should run a 10.5 in the rear with a +20ish offset.

What wheels are they?

The +15 will get you the most flush. Is the car lowered?

Thanks for the quick response.

They are Ambit wheels. I am not sure I am going to go with yet them but I need a square setup of 18 x 9.5 . I want to run in a STU class for autox and that only allows me to use 255 tires, sucks I know. But if I buy a 9.5 rim I can at least run 255 and 275 tires on it if I wish.

If I do the +15 in the rear will I need spacers to bring the wheels back out some so they don't look sunken in?

it depend's on your rear camber setting.
my factory 18x9+15's are only 10mm from being flush w/-1.7 camber
that's measuring off of the bead of the 275 tire.

Car is dropped about an inch front and rear but I can change as needed. I don't really care about stance as much as I do performance.

Well stock sport are 10" +30. A 9" +15 will extend 26mm and retain the same stock inner clearance. I wouldn't recommend using a spacer if you plan on autocrossing the car.

Thanks for the great input everyone much appreciated.

So if I run 9.5 front and 9.5 rear will the front end up being flush and the rear looking the same as it does stock? If so would I be better off with the +22 up front and the +15 rear?

The +22 is the safer bet.

You can get away with the +15 up front if you're not too low. It will be nice to have +15 all around so you can rotate tires.

Good tip. Thank you!

Same size wheel & "flush-fit"-there is right at a 1" difference in offset.
example (+25 front,0 rear) pending camber.

I am looking to put my old set of Vossen CV5's on my 15 Nismo in the spring. They are 20x9+35 245/35 and 20x10.5+45 275/30.

I was wondering what a good size spacer to run would be?

I dont want it too aggressive because the new Nismo has fender flares that stick in the wheel well more than the fender does.

I am lowered on coilovers, from the center of the fender to the ground is 26.25" in the front and 26.5" in the rear.

Thanks

Pending on your camber setting; 10,15mm front & 25,30mm rear/ also a 285/30 would even up the tire height.

Easiest way is to mount them up & measure

Camber is within factory spec, give or take ~.3

I would like to change the tire but they still have alot of tread left so I plan on using those. They were off of my G37, I probably wont run them for long but I want to go to a couple of meets/shows in the spring and wanted to have aftermarket wheels.

I would have to change my wheel studs in the front if i ran 10mm correct? or even 15mm for that matter. Rear i believe would be fine with bolt ons

If I were you, I'd run a 15mm spacer up front to give you an end offset of +20 and a 30mm on the rear for an end offset of +15. You shouldn't have any rubbing issues with this setup.

Question about spacers
 

Hey everyone! This is my first post on the forum, so forgive me if I sound like an idiot...
I have a Touring without the sport package, and I'm wondering what size wheel spacers I should get.
I have Kumho Ecsta Platinum tires and 18 inch TSW Bathurst wheels, and I hate how the rear wheels/tires sit inside the wheel well (the rear wheels are more concave than fronts, so the way they sit inside is more noticeable than stock). I had the rims installed in July of 2015, and I've been looking on the forums to find some info, but for the most part I haven't found any answers pertaining to my situation. Also, I am not planning on lowering my Z any, and it is still at the stock ride height from when I got it in 2014.
My preference would be that tires either be flush with the wheel well or for them to stick out slightly farther.
Any advice would be greatly appreciated, thanks.

In the rear, my current tsw's are a +27mm with a 15mm spacer. will i have any issues rubbing a 305 in the rear?

For everyone asking how big of a spacer to get... measure it first. This will get you in the ball park of what you need.

Grab a long straight edge (piece of wood, even a cardboard box) and a tape measure/ruler. Hold the straight edge against the fender and straight down. Then measure the distance between the wheel/tire and the straight edge. I always measure from whatever point sticks out furthest. In this case, the rim since the tires are stretched.

So as you can see, if I want this rim to be in line with the fender, I need a 10mm spacer.

We need to know the width along with the offset.

Offset was mentioned at a +27mm. width is 10.5"

+15mm spacer

i'm thinking it will be very close with a 305
