FAQ: Official wheel "SPACER" thread!
I had someone step on the brake but it would still move a bit while tightening the nuts so I just used a small piece of 2x4 I had laying around and that did the trick. It just rained last night making the car look like I just came back from 4x4ing. I will wash the car tomorrow or the day after and upload some pics!
Need help finding shorter length replacement studs? 
From JasonZ-Ya's post...
The Z OEM studs are M12X1.25 with a 14mm knurl at the head
FRONT OR REAR: M12X1.25x42 (42 mm length) OEM F/R replacement -
NAPA P/N 641-3210
AUTOZONE - 610-378.1 98353.1
I called ARP and they said they can't match those sizes. I don't get it, I thought someone posted ARP replacement part #'s?
Another post showed 20mm spacers with OEM studs protruding +3mm. I have 15mm spacers (3+5=Pie squared?), so I would need 34mm overall length studs.

My other options are:
1. taking the car to my fabricator and paying big time to have them professionally matched cut.
2. Selling the Ichiba's and buying Eibach's with extended studs which still requires removing and pressing in studs. Although I did see a thread where someone whacked them out with a hammer and they got pressed in when the lugs got torqued.

From JasonZ-Ya's post...

Where could I get "quality" steel studs, any sponsors here? I don't track the car, so I really don't need titanium or T71 aluminum but would want stainless or high grade steel that won't rust and/or strip easily.

Reply from ARP with part # 100-7716. I'm really not sure how 72mm is 8mm shorter then 42mm. They must be using the governments budget calculator.

That means my only options are:
ARP extended is way to much to cut in half. RA's price for Raybestos brand w/ship+tax = dealer retail price. Finding a machine shop to cut them is like asking for a favor.

dude, when i went through this, i found that the measurements on studs vary...some measure from the end, others measure from the base of the knurl/mount face....
So;... the "mm" dimension given on their websites is complete crap unless you know from where the measurement began...get it?
I literally have a few sets of 10 studs in boxes too long or too short for my needs....
you have to email directly to each vendor and have them measure, provide a picture and hope they know how to use a damn ruler...
stoopid i know...
you literally have to email them this picture and tell them what you need:

Two questions:
Any rub in the back on the 30MM? I realize tires can be designed differently etc but it appears even without the back being rolled, I am safe. Is this right?
Also, I believe 20MM in front would make it look like the 30MM on the rear as far as how the tire sticks just a touch inside the fender line at the top. Is there any issue running the 30/20 setup as far as the VDC is concerned or are the only issues there strictly with tire size. I know VDC is more than just "traction control" in the regular sense and I don't like having electronic anything kicking in sooner than it is supposed to.
Thanks in advance guys and gals.
BTW I may do a MILD drop in the future, maybe 1/2 inch tops, but I am not looking to dump it anytime soon, or anytime for that matter. Not sure if this will play into the above or not.

Alright so these are the same wheels and tires I have. Looks like 30MM fits perfectly at stock height in the back and the 25MM sticks out a touch further in the front. I DID read the entire post, all 45 pages, and see nowhere where someone is running these stock 03 Touring Style wheels with a 30/20 setup.

Just addressing the first question: I don't think you will rub even without fenders rolled, at that ride height and "Stock" camber settings. As the suspension compresses, the wheel effectively cambers inward (more negative), which will give you plenty of clearance between the tire and the fender lip.
Making sure I have enough set aside to do it right, however that may be.
2) VDC will only be affected by tire diameters, and not overall offset/width. As long as you are sticking to OEM tire diameters front and rear, you will have no VDC issues.
3) Unless you install adjustable camber arms, when you eventually do your mild 1/2" drop the wheels will just camber inward (negative) that same amount that they would right now if you were to compress your stock suspension by the same 1/2". So you should still have no rubbing.
Yeah, I was hoping to not have to get into adding suspension components like adjustable camber arms etc. I think a simple set of H&R springs, and maybe some accompanying shocks, would be sufficient for where I want to end up with it.
I am considering putting spacers onto my Z right now, or at least I want to.
I am not exactly too sure what sizes I need to get and go for, yes I have used the search feature and I didn't pull up too much useful information.
What I have planned is Spacers then coilovers and lower it and have a nice stance.
What size spacers should I be looking for?
Thanks in advance

Thanks again everyone.
I just picked up 2 eichiba 25mm spacers cheap locally.
I am paying too much stuff off right now ( and trying to finish my AR build)
Question: Can I run these 2x 25mm spacers in the rear? Will it look stupid?
Thanks guys
