FAQ: Official wheel "SPACER" thread!
Hmm..waiting to install my Tanabe NF210 springs and 25mm spacers(F) and 32mm spacers(R) this weekend if I can make the time for it. Today I was a little proactive and had the rear fenders rolled just in case. I'm on stock 18" wheels/tires.
UPDATE: Installed rear springs and spacers.. VERY satisfied with its new stance in the rear and very excited to see the final drop after it settles. Good thing I rolled the fenders because it would of rubbed. I'm doing the front springs and spacers this weekend! Will post pics after everything is completed

Hay i need recommendation on Wheel Spacers for flushing my Current Wheels setup is.
Front
19"x8.5 ET32
245/35/19
Rear
19"x9.5 ET35

What size of spacers i do use for rolling the fenders or without rolling the fenders.?
Thanks

2. Once you have determined how much you need, use the Tire Calculator - https://my350z.com/forum/2003-2009-n...drive-a-z.html - and play with the offsets to see how much offset you need to take out (which gives you the size of the spacer you need).
As a very GENERAL note (keyword: GENERAL), Z33s, with those wheel width dimensions (8.5/9.5) need a net positive offset around +15 to roughly +20 to be even with the wheelwell arches. But this is NOT absolute.

How do I know if Wheel spacers fit? I read it's about me having to have gaps on my wheels or something like that... I don't have it but if i get the Hubcentric wouldn't I be okay? An if so how much that I won't rub my tires are 20x8.5
This may be a noobie question or a simple math problem. I just purchased a pair of Eibach hubcentric 15mm spacers for my front wheels so i can get a little more flush look to the car and maybe a bit better handling however it is not a drift car. My current setup up front is 19x8.5 245/35/19 and 19x9.5 275/35/19 rear. My question is if i install the spacers up front will they essentially jot out more than the rear and if so whats the size i would need to balance it out? Any advice/help is appreciated, thanks.
Whats your current offset of the wheels?

From a stock fitment on 18" wheels you can fit 20mm in front and 25mm in back no problem, even with a 1" drop. That may help you calculate your 19" specs that you're trying to figure out.
If your wheels looked like they were the same depth within the wheel well before your front spacers, then of course adding 15mm up front would mean you need at least 15mm in rear as well. The fronts WILL look wider without giving the rears a spacer.
I think you'll need a 20mm for the rear, but personally I'd go 20mm front and 25mm rears, don't take my word for it but I think that will fit on 19's....could be wrong.
Hope this helps,

^^^THIS.
No one can answer your question without knowing the existing wheel offset.
Ultimately for wheels that size, you're going to want somewhere around +15mm effective offset to work without fender massaging and/or camber to fit about right FRONT OR REAR. So, as an EXAMPLE, if your fronts are, say, 30mm, the 15mm spacers will get you where you need it to be.
Use the tool: https://my350z.com/forum/tire_rim_calculator.php to determine how far you can go. Note that inner clearance available is about 25mm (maybe 30mm) max at full lock even though the wheel will appear to still have clearance in straight line.
Depending on the wheels, you may or may not need spacers at the rear.

One other note about using spacers: don't forget about stud lengths! Don't expect to use your OEM studs and lug nuts with spacers 15 mm and over. Depending on offset, a spacer will not leave enough thread for you to safely mount your new wheels. Nothing like losing a wheel on the road or track to ruin your day!
Also, it's a good idea to buy longer studs made of stronger material, since you are effectively increasing the axial loads by using a spacer. I recommend ARP, who make some of the best fasteners in the world, for a wide variety of lengths and thread patterns for extended use as wheel studs.

If anyone has read my posts that contain the word "spacers", it's public info that I don't like them.
BUT, hypocritically
While they have helped with fit and offer, arguably, an OK performance use (note I didn't say "performance improvement"), I still hate 'em and am conscious of their presence each time I drive on 'em. No, they *probably* won't fall off but I still prefer naked hubs. Heh heh.

Proper sized spacer and proper installation has little danger, but its another part that has potential to fail. I personally dislike spacer and would rather but wheels with proper specs, but i dont see a problem with them when used properly.

Thank you guys so much for all your responses! These are all great tips and suggestions. I knew offset somehow played a role in this as well. Ill have to look that up but i believe its around +22 but ill make sure. the wheels are volk gtv. I agree with having wide enough wheels to where spacers arent required thats the best option however i couldn't turn down the deal hehe. i guess I should clarify my question. I currently like the fitment of the rear and it will look as i want when i drop it; flush with the wheel well, it does have slightly less degree of camber as well. but i want the front to match without having to change the specs so my worry was if the 15mm spacers will affect performance negatively if the front ends up being wider than the rear i can imagine that wouldnt be good. The spacers came with built in studs and i have new volk lugs as well. I tried to post pics but i guess ill have to go premium haha. Thanks again guys!
I have been sifting through threads on here to find what people say is the best set up for wheel spacers for stock 2008 18inch anniversary wheels. I haven't seen anyone give a best fit. Brand, size that won't rub and look best? Anyone have some suggestions? Did a little measuring, front 1inch rear 1 and 1\2 sound about right?

Im new to this as well so hopefully this is just straight forward but i got some rohana rc22 not staggered on a deal. Im going to call them and see if they have the rear spoke clearance or not.
So i now have (4) 20" rims already tired. Width is 9" for all four. Bolt pattern; 5x 114.3 and they're offset is +35 all around
I basically test fit these onto my 350z that is lowered on Bilstein pss10s but setup to almost a maximum height. I think im going to need my fenders rolled if im correct? And my rears fit fine with no spacer (they clear my brembos) but the front hit against my caliper by about 2mm when i tried test fitting with a 8mm spacer.
I just want these rims to fit and not rub but also look good any ideas on the perfect spacer combo i need? I know i need a minimum of 12mm on the fronts to clear.
Is it smart to run spacers in the front and not back if theyre not staggered?
I also already purchase hubcentric rings in the proper bore size. I bought 2 sets to be sure (one plastic gorilla brand) one aluminim set off ebay both at the bore sizes 66.1 to 73.1 (which is what my aftermarket rims are)
So suggestions on spacers please
