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 :eekdance:. 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 :driving:.

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...

Lots of good info and opinions here. So.. my 2 cents.... H&R bolt on (not the loose stud one) worked great on my 2012 (red also) with 18" stock, 20mm front/25mm rear. When I got ready to trade I removed them, and used them on my new 2014 w/19" Rays, Sports Pkg, with no issues at all.
Go to H&R website and enter your car information. Be sure to read the notes (click on) to be sure of fit or call their 1-800 #. The 20/25s look great and fit perfectly. Sorry I don't have the part #s anymore.
I didn't know anything about all this either at first, but it's not hard.
Cheers,

So I finally took the plunge on this yesterday. Here's my story.

Since everyone on here seems to have differing opinions it was hard to know what size to get. I decided that using 10 or 15's was not something I wanted to tackle or pay for (since you have to remove the brakes and the hub and swap out studs) . So it was either 20 or 25. Since you can't return them after putting them on, and they cost $150, I decided to eat a little freight and only order 2. I had both of them put on the same side of the car so I could see what 20 looked like up front and in back.

Here's what I've determined based on what I have on my car, with stock tires and sport wheels, stock camber alignment. All observations are from looking straight down from the top of the outside fender.

FRONT
15 would be about 1/4" inset
20 is flush
25 would poke about 1/4"

BACK
15 would be flush
20 pokes about 1/4"
25 would poke about 1/2"

I am not a fan of poke. Poke to me reminds me of 2 things, 4 x 4 trucks (which look good with poke), and ricers with Honda Civics with ridiculously offset wheels (which looks stupid). I prefer flush. Knowing this, I LOVE the 20's on the front. They are perfectly flush. BUT, 20's on the back are slightly too much. I would prefer 15's better. Anyone liking the 25's on back likes poke. So if you want flush, 20 front and 15 back is the way to go.

So I had a big decision to make; do I buy 2 more 15's for the back and go through the hassle and cost, or do I just stick with 20's even though they poke slightly. I decided to just stay with 20's. I'm 95% happy with that look. It's not perfect for me, but I just don't want to screw with the other kind, or pay for it.

Pictures up next. (Just uploaded the pics. For some reason they are now darker and not as clear as they are as originals. Sorry)

Today I did a test install of one 20mm spacer on the left rear of my Z to see if I would run 20s or 25s. The plan was not to get too fancy because they were coming right back off again. We dropped the car back on the ground, and I drove it back and forth a few times, braking at each end to get the car to settle.
I took some pics but they were on a BB and were so atrocious I haven't posted them. My pics look JUST like these. There is no way I could go to 25s on the rear. I bought one pair of 20s, now I'll get a second pair.

With reference to my above post;
There were absolutely NO issues with the spacer mounting lugs extending past the face of the spacer, so cutout room on the wheel is of no consequence. (the stock studs did though) The room is there, it's not needed, at least not for the lugs. I will still have to look at the front wheels again.

Which one would you guys prefer: Ichiha, H&R or B2Desgns spacers? Looking spacers with great quality.

Any input ?

Just go 20/25 or 25 all around. I have 20/25 on mine with Swift springs and the fronts aren't as flushed with the fenders as the rear.

Is there any harm in installing 25 mm spacers In the rear and no spacer in the front?

I installed on rear only. Stillen's website says you cannot install H&R DRM (type 2) spacers at all up front with OEM wheels. I know there is a bolt on the hub to prevent rear wheels from being accidentally installed on the front. Not sure if this is the cause, but you can remove that bolt. Or maybe the OEM front wheels do not have any kind of recess for the spacer stud to extend into.

Ugh. I was trying to install my 20mm/25mm bolt on spacers tonight before TX2K16 tomorrow but came across that bolt in the front. I had no idea what it was for, but obviously, could not install the spacer with that. It was late, so I decided to just give up and come look on the forum about more info on that. What a dumb bolt.

I assume it's just a threaded on fastener that should be easy to remove without any hassle? Anyone know for sure before I run into another surprise trying to remove it?

Its there so you dont put the rear wheels on the front and vise versa. It just unbolts

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.

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.

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

hrmm the poke past hub chart is confusing for me.

Only want flush, no poke :) 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.
