So ichiba extended studs to replace your factory studs???? so you need to know the knurl size to fit in the hole of the Z HUB??

I have a factory replacement stud at home that I can measure its knurl and then ill know and i can post back on here............

Try calling autozone or an autoparts store and asking them to measure the knurl for you. Usually autoparts stores have digital calipers and micrometers on hand...

ichiba doesnt have it listed or customer service??

yeah, to replace my factory studs.

well, HERE is ichiba's nissan/infiniti page... they don't really explain. go figure.

EDIT: i just emailed them... waiting for response. in the mean time j, i'd appreciate if you can measure for me... thanks!

 

i measured my oem replacement stud knurl to be 14mm.... actually about 14.4 but ya...

I search couple of threads, and most of them didn't state if the offset require roll fender or not.

I have Work CR KAI, here is the spec

Front: 18x8.5 +25, 245/40/18
Rear: 18x9.5 +20, 275/40/18

Now I want to put spacer to pull out the wheel more

What I have in mind is to put +10mm front and +5mm rear, +15all around (I know this one don't need roll fender)

But what about +15mm front and +10mm rear to make it +10 all around? Do this require roll fender, or maybe Front +15 and Rear +10?

I have the BC racing coilovers and I don't want to roll fender...

Thanks for any advice.....

 

How far do you want to move the wheels? 5 mm? 10 mm? 20 mm? There you go.

 

Dude you cant measure 15mm and see if it hits or not. Theres no special formula just simple measuring

 

It is nearly impossible or obsurd to have a magical list that will or will not require a fender roll..........there are way too many variables......

one guy can have +10 offset like the wheels you mention, but he rocks a super negative camber and doesn't rub??? you willing to do that, trust the list of data from others???

Too many factors.........
ride height, offset, - camber, tire size, etc.etc...

you have coilovers, so you can make some adjustments once you "try" the spacers your thinking........but then again you should just "roll your fenders" get over it....

TO EVERYONE:
So the Z has a crappy fender lip...........just like anything else, mod it...mod it by rolling it.......it is what it is.....

Once again see post 15: https://my350z.com/forum/7149697-post15.html
I will not answer "roll fender questions" anymore than what i have already...

Duro78,

Sorry, but DAVIDV is right.......measure and there you go...

mimic a bump.....get your car, jack it up, jack up the tire and mimic a bump and measure!!

this guy did it with a lift and lowering the car onto something to look for bump steer, but you can do the same to see "if" you are gonna hit the fender lip.

How often should we re-torque the spacer? assuming we did it correct at the first time. The car shop people said I should re torque it every 10k miles, is it necessary?

BTW, anyone know the torque spec on the Ichiba V2? Is it 80 lbs? Same as our wheels?

 

I Have never seen any actual data/instructions or anything with any of the spacers i have come across to give a factual answer......

the shop's recommendation is just that, a general rule of thumb recommendation.......I'll tell you this, I change my spacers, wheels, etc often with tracking the car........in doing so i torque them every single time!

10,000 sound fair to me..........sure why not.....necessary, I would say probably not, but thats because i do mine often......i haven't seen them ever lose torque??

as for torque spec's I did have an instruction sheet that said 90, and nearly all spacers are made from the typical 6061 machined aluminum so its fair to say about 90 is more than adequate..

What size spacers for 08 stockers would I need to be as close, but not going over or wider than the Volk GTS 19x8.5 +24 and 19x9.5 +21 fitment? Sorry, I couldn't read through every post.

 

Sorry but thats your problem...........as good examples of stockers with spacers are on the first page for you to decide...

-J

 

This. If you want the information, you'll read through this thread to find it.

 

DING DING DING* That's what I did...

Just drive on a few 2x4 pieces of wood and your car should compress enough where you can see how much space you need.




Oh..BTW: "This guy" also has a full article in this month's Modified mag sharing his SCCA adventures.

 

YA, from what i see "sasha" is a bad ***!

-J

 

I meant what spacers would I need to be as close to what the Volk GTS 19x8.5 +24 and 19x9.5 +21 fitments would be when installed on the car considering the difference in rim width and factory wheels offset. Basically for the tracks to be similar. I actually did read every post after asking that question

 

Did you read post #15 - where the link on top gives a "offset calculator" to compare two wheel specs??!??!?


-J

 

Thanks

 

Apparently didnt read well enough. Nice of you to step in and spoonfeed, Jason. LOL

 

ya no kidding...............nearly every question is answered here in regards to spacers................
