Thanks in advance for any help.

P.S. If anyone has a better place to get spacers that would be awesome, not trying to get anything super expensive.

No one here is going to be able to help you without wheel specs

Except I can tell you those look like cheap, generic spacers. Spend a bit more and get a proper set like H&R. Check out Z1 Motorsports.

On z1 i only saw a 20mm I need at least 25mm to clear my calipers, and i was hoping to get ones with studs built in not the ones where you have to get extended studs because when i go back to my stock wheels im not gonna be using spacers.

Thanks for your response, ill look at some other companies to see what they have. I was just wondering if the spec of the spacers i found on amazon was correct for my car to ensure proper fit.

As I already mentioned, no one is going to be able to answer that without you providing you current wheel specs ...

Thanks for the link, I don't know how I missed that. As for the fitment I mean the spacers fitting to the car. But now that you showed me these I think I'm all set.

Thank you for taking the time and helping my noobness.

Yup, those should fit just fine.

For the record, hub size on the 370Z is 73.1mm. The inner bore size is 66.1mm. Hubcentric rings ?

RoadsterFun · 08-29-2016, 10:21 PM

Any difference in quality between H & R, Ichira, or Eibach? Or other recommendations? I'm going with 15mm in front and 20mm in the back with the stud replacement style of spacer...

For the ney-sayers that are so worried about spacers causing undo wheel bearing wear, I don't understand your argument for the 370z.

All we are doing using spacers with sport wheels or any aftermarket wheels is duplicating the way a Nismo looks by pushing the wheel mounting point outward to dupe the Nismo's deeper wheel offsets to make the wheels flush with the fenders. This essentially puts the Sport wheel/tire combo in the same place since there is no difference in the mounting points for all 370Zs regardless of model. This means the centers of the wheels are the same as the Nismo so this means Nissan designed it to work with Base/Sport/Nismo sets of offsets and their different loads of the wheel centerlines.

Lowered on swifts.

nismo rims are 19" x 9.5 front and 19" x 10.5 rear.

Does that mean for rear I would need 25mm and front 20mm if i'm lowered?

Edit: Looks like 15mm all around.

I assume dragus is talking about the new Nismo wheels that appeared, starting in 2015. I'm curious about the same. I'm not sure what the specs of the new Nismo wheels are, vs the previous Nismo wheels, vs the other 19" wheels on the other trims...

I too would want just a flush look. What's the point of going "poke"? Is the ultimate goal to camber the wheels, or do guys just actually want them to stay poking out? Shiiiiet I have much to learn about this stuff. Yup, just like everyone else here

By the end of the day, I want the car to remain looking stock. I want to improve the stance a bit, by doing a modest drop and push the wheels out so they don't look so sunken, but overall, have the majority of people think the car is unmodified.

MarksZ34 · 09-11-2016, 03:43 PM

The new Nismo wheels as well as the newer Sport wheels are the same offsets as the old versions. I know there is more info on what spacers are fit for a Nismo on here but not sure it is in this thread. Do a search.

After seeing a fellow Cleveland Z Club member's car with front and rear wheel spacers installed (20 front and 25 rears), I really liked the way the wheels filled the wheel well. I decided on Ichiba spacers and when installed, they were perfect. They fit like a glove and was exactly what I had in mind, until:

A friend and I drove to Watkins Glen racetrack for an event sponsored by his Alma Mater. When I entered the freeway, I hit about 65 MPH and I thought that the wheels were going to fall off

. Anything above this speed, and I could hardly hold on to the steering wheel. At the first rest stop, I rechecked the torque on the lugnuts and there were perfect.

The car felt to me that the tires were way out of balance; mostly the fronts, but in the rear as well. Every time we stopped, the nuts were checked and were found to be tight.

After the 5 hour drive, my arms were tired and the next morning before our laps at The Glen, I removed the spacers in the hotel parking lot. Once removed, the car was perfect again. At speeds up to 100 MPH, the balance was right on

.

So, fellow wheel spacers users, what the heck is going on? I made sure that the spacers were absolutely centered (the spacers are hubcentric) and the mating surfaces were clean and had no debris. I have been working in a torqueing company for 42 years and I know how to secure wheels in the proper sequence and torques, so that was not the issue. I love the way they look, but if I can't figure out what's going on, they will NOT be reinstalled.

Any insight is appreciated...

I know this post is about 1.5yrs old, but would like to know what was the outcome in resolving the issue.

As long as you size the studs properly, you should be good.... can you get studs that are 15mm longer than stock?

RanRich · 08-22-2017, 10:14 PM

I have 15mm stud replacement spacers from H&R all around, but am toying with the idea of Swift springs and would want to jump to 20mm for the rear. H&R said I couldn't just swap the spacer itself because there wouldn't be enough thread, so I am wondering if I get a pair of 20mm bolt on's will the extended studs from the 15mm set fit in the cavities in the back of the wheel? (Sport model for reference)

RanRich · 08-29-2017, 08:58 AM

Bueller?

TLDR; I have 15mm stud replacement spacers, can I use 20mm bolt-on's in the rear without issue?
