Spacers
 

I had front spacers installed today by the dealer. In order to install them, the calipers need to be removed in order to install the new studs. The dealer charged me over $300. Then I was told that the spacers needed to be removed in order to past the annual state inspection. Did I get overcharged by the dealer and is it worth it?

Whats their labor rate?

Modshack DIY: Front Stud replacement/ Spacer install

Why removed to pass inspection?

I can't tell from the bill. I'll have to call and find out. Is it true spacers are for off road use only?

The dealer said that the spacers will not pass inspection in PA. I know I can probably take it somewhere else and hope they don't notice the spacers!

Spacers not passing inspections is definitely strange.

As far as I know, the wheel cannot extend pass the fender. As long as you don't do this, you should be fine.

So it took the dealership over 2 hours to install those...DAMN!

They only have the version where you have to place extended studs in??...I figure there are spacers out there you that have studextension already on them...just like every other spacer out there. *Shrugs*

According to this post below the bolt patterns are the same as the 350z...you and every other 370z owner can get spacers just like the pic below up to 30mm if thats the case :/...Only takes about 10 minutes a tire to install if you have a torque wrench. I suppose the only question is, will they fit the hub and if so are there hubcentric rings to fit in :dunno:

Actually, I don't think you can use those. From what I've read regarding spacers on the 370z, the only ones that will work are the ones where you need to replace the stock studs with extended studs. The spacers with the built-in studs WILL NOT work.

I did use the Ichiba 20MM version II spacers that you use on the existing studs for the rears. But I believe I read that you need to install version I with the new studs for the front.

That is correct. The machining on the front wheel is different and does not have a deep enough or large enough recess to clear the original studs. Keep in mind you will also have to remove these (Type 2) to use the spare..

Rear wheel:

yeah, and I found out I can't use the type 2 on the rears with the Nismo wheels either, as the studs still contact the wheel when installed. I'm having difficulty banging out the new longer front studs,so I am going to try a 25 mm spacer in back instead, as that should fully cover the oem studs when installed.

They are hubcentric to both the wheel and the hub.

ugh spacers are FAIL!

Why are they a fail? They increase the track width. They are attached by machine pressed bolts. If you go with a wheel that has higher offset to bring the tires out to the lip, you're just essentially adding an aluminum spacer to do it, just that it's attached to the wheel rather than the hub. And, they significantly improve the looks of the 370z. I showed up with Ichiba spacers in hand and Big Brand Tires charged me $120 to install both front and rears.

can someone please explain from a spacer standpoint, what exactly must the spacer look like physically in order to be considered "hub-centric"? What would a non-hub-centric spacer look like?

Hubcentric spacers are machined to fit the hubs precisely on the hub side and the center bore on the wheel side. Sometimes they are machined in one piece, sometimes, like the Ichiba, 2 pieces.

So its that separate hub-ring part that makes the differences since it acts as the connecting interface between the wheel hub and the actual spacer ring?

Yes

Mod.. I saw on your DIY you went 15mm on both front and back, any reason you didn't go 20mm on the rear?? Am close to ordering these.. definitely 15mm for the front, but have seen 15 and 20 on the rear mentioned here...just looking for some additional input before dropping the wallet.

Thanks

20's on the back
 

i installed 15mm in front, 20mm in back. the back looks killer

Word of Advice, if your going to run a spacer ALWAYS get a hub centric spacer. Non hub centric are known to move around and are not really safe. Hub Centric Spacer are safe, i have a couple friends that road race with hub centric spacers on and never have problems!

I had a set of non-centric (didn't know that at the time) on a Cobra that I tried in order to put Goodyear 315 DR's on the rear and clears the IRS bolts. I have to say that whenever I cornered the backend of the car never felt "safe" or stable as it always felt like the back wheels were never solidly connected to the wheel housing. I would always feel a very slight wobble in the rear wheels when cornering in the slightest...particularly on highway exit ramps.

I learned later on that with the non-centric spacers that with any hard-launch from a standstill I was risking snapping the studs each time. Fortunately I never had them on the car long enough to have that happen.

Not soon after I switched to a Nitto 315 DR's which are about a 3/4" less wide than the Goodyear ones so I was able to eliminate the spacers all together as they cleared the IRS bolt due to being less wide. It was like night and day in terms of the backend without the non-centric spacers.

I learned from that whole experience to "Just say 'NO' to non-centric spacers".
