you shouldn't have that issue if you bought spacers that were intended for the Z.

See some people will get spacers that have a hole pattern of 5x114.3 but the center HOLE in the spacer itself wont be 66.1, it may be larger, which also means it must mount to the 350z Hub face surface like this link explains - https://my350z.com/forum/7388163-post81.html - same rule applies when installing the spacer - if its not sitting on the hub in the spacer center hole, then don't trust the tapered holes to align your spacer....

PIC, i don't have pics, but i may just have to figure out a diagram/schematic way to best explain these poor install wooo's...

Answer this question:

1. What is the hole diameter in the center of my spacer?

like shown here -


if its ichiba, project kics, etc.....with our with out studs, doesnt matter........WHAT is the center hole diameter of my spacer???

if you have hub rings then you should be golden as the hub ring will sit on the Z hub snuggly and the spacer will slip over the hubring snuggly.....THEN you know your centered....

if NOT - then watch your install and ensure the spacer is installed centered.....if not installed centered and flush, then you can have vibration as your wheel and all is not spinning on center!!!??

Hey guys, I have been researching for a while now and I was wondering if someone more experienced can give me some insight on this. I have Nismo LMGT4's there, 19x8.5+25 and 19x9.5+30. I wanted to get 20 mm Ichiba V2 spacers all around. Would I need my fenders rolled in the back? And does anybody have any idea if this set up would be flush with the fender?

Any help is appreciated,
Thanks,
Dan

 

WHAT SIZE TIRES? - the meater the more chance of fender contact....

ARE YOU LOWERED? IF SO WHAT SPRINGS? HOW MUCH OF A DROP? ETC, ETC....ETC...

DID YOU MEASURE TO SEE IF 20mm will do what you want??

its best to measure and try from there. if fenders need to be rolled, then go have them rolled.......its the name of the game with the Z............

This isn't directed to you, but im just saying in general to anyone that asks these questions:

---- You cant have the "FLUSH" look and then complain that you DONT wanna roll your fenders ----

You gotta pay to play...the Z isnt cheap to mod....hell the only cheap mod on the Z is the cool short antenna! thats why it is/was my favorite mod!!! LOL...see my sig...

Wow, sorry I totally forgot. My tires in the rear are 275/35 in the back and 245/35 in the front.

I'm not saying I don't want to roll the fenders, I most likely will when I install the spacers. Aren't the fronts already rolled?

I am looking to lower on Stance coilovers when I get the money. I am at stock height now though, so no problem yet. I measured from the tire to the fender and it seems as though 20mm spacers would be sufficient.

Is it correct to measure from the outer most point on the tire to the fender and whatever mm that is, that would be the correct size spacer to use?

 

no problem....ya with those it should be fine!


cool, ya, be open to having to do it....

yes the fronts are already rolled back - anyone can tell, go to your car and place your fingers along the lip of the fender, you can see the fronts are already forced at an angle that a roller would have typically done..FROM FACTORY.....so your golden for most offsets - CAN YOU ROLL IT MORE - SURE.........HECK, you can also cut the lip off too.....i know peeps that dont fug with rolling fenders, they simply cut the lip you would typically roll and treat the cut/unfinished edge....

Yes, thats what i do for what i call a good rough guestimate...you must remember thats a rough estimate as of course the suspension geometry will MOVE with the new wheel footprint to the ground....and suspension geometry articulates up and inward as the car suspension COMPRESSES....

Get what im saying?? so start there and make adjustments as you see/wish for the look/flushness you desire...

-J

 

Nice, thanks for the info. I am somewhat understanding most of this. So just to clarify...

Do you think I could hold off on getting the fenders rolled while the spacers are on at stock height, and deal with rolling the fenders when I decide to lower my car?

Thanks again,
Dan

 

ya, i think youll be good......

I have a 2003 Z with 17Inch OEM wheels I was thinking of doing 25/20's Ichiba V2's. My question is would they just bolt up or would I have to make any adjustments to the studs. Also I am planning on dropping it with Hotchkis springs, would that create any issue. Thanks

 

Sorry but read post 1-16: stud related - pay special attention to post 6-8!!!- here -

As for the hotchkis spring drop and oem 17's you will be fine!

-J

 

This is a great write up, I see what your saying on the gapping. You think 25/30 will rub after the drop?

 

For people wondering about rubbing; I had a 1" drop in the rear with 275/40 rear tires, and my wheels are a +30 and I had a 25mm spacer. And yes it rubbed without the fenders rolled. So I just had them rolled and now it is fine.

Edit: For anyone looking; I am changing my wheels and selling my 25mm Concept-Z Spacers with built-in studs. So if anyone is looking for some in like-new condition for much cheaper than new, shoot me a PM. Just looking to unload them.

 

Any ideas on why my car vibrates after installing 10mm spacers? =(
They are hubcentric..

Edit: after reading through this thread i can confirm that i have hubcentric rings as well..my spacers are eibach spacers..made for the Z..

 

^ what wheels do you have? stock ?

 

great thread and great info. I am looking to buy spacers soon for my LMGT4's.

I noticed there is a company on ebay selling vehicle specific/hub centric spacers now and not just the universal crap. They are also the type with pre-installed studs.
Anyone have experience with these? They are a good $50 cheaper...

 

LINK to ebay postings or whats the ebay sellers name??

-J

 

http://cgi.ebay.com/ebaymotors/15MM-...item518aa14ac8

Check 'em out.

 

okay, we all know the link will die for that listing, so below is a screen shot with the ebay sellers name - " optionselects "


Here's my go at it.


MACHINED/FABRICATED:
A spacer is machined piece, so who knows how well their tollerances are, but then again who knows how well they are between even the well know spacer companies - kics, ichiba, etc....

I would look for 6061 - which is what those are and save give them a try so long as they are per your cars specifications.

Project Kic's slap on my Z with ease, where i have to kinda push on ichiba's....so machine tolerances are different on all pieces..........


SPECIFICATIONS:
And from this spec list on their summery, they seem good for the Z.
Spec:
Bolt Pattern: 5/114.3
Center Bore: 66.2
Thread: 12x1.25
Spacer Size: 15MM

STUDS:

Okay, one of my only gripes i have ever had with different types of spacers is that some companies use some cheap studs.....i have misthreaded a spacer stud or two and have had to press the studs out.

Here is a link in this post (POST 14 of this thread) of where i did that with kics, but i have had to do it with ichiba and other brands as well.

https://my350z.com/forum/7149681-post14.html

Also, having lug nuts not hold torque, due to cheap studs...so keep that in mind if you buy ANY spacer really, keep up with them, as in - recheck their torque later down the road........if you notice constant torque slip....after a given amount of time, or whenever you want (its your car) press out the studs and purchase some better ones...if thats the case???

For $88 bucks, give it a whirl...........let us know how it goes...

-J

 

Nice. Great info.

Just bought a pair from them and I will post impressions when I get them and get them installed. I have never used spacers before so I don't have a basis for comparison, but I will let everyone know how they look and quality, etc.

 

^ sounds good to me...what was shipping on them? when i clicked it, it wouldnt give me the standard rate....?
