Can anyone advise where to purchase 1/4" hub centric wheel spacers?
Many thanks in advance !

I'd contact Anthony at LG Motorsports. Pretty sure they will custom build you spacers to your spec. You can also try Motorsport Tech. I haven't used them myself, but have heard good feedback over the years about their adapters and spacers. I think H&R still makes wheel spacers as well, but haven't checked recently. Good luck.

Thanks appreciated

Many thanks for the advice

1/4 spacer does not have to be hub centric as it will not extend past the wheel bearing. Not until you get to 1/2 do you need to worry about that.

Make sure you have enough thread engagement.

I've used Southwest alum spacers for years.

I found a 1/4" set on ebay that was cheaper than any of the usual vendors.

Personally I would do a better stud on a track car no matter, but anything in there they need to have a longer stud.

ARP makes a nice one that is fully threaded but not much longer than stock and gives you much more thread engagement even with 1/2" spacers in there.

I haven't gone through the effort of measuring engagement (yet) but how much spacer can the stock studs take before I need to swap for ARP extended hardware? I've got some AS legal 18x9.5's on the way and will need at least 5mm of spacer to be legal but would prefer 1/4"...

Thanks!

I "think" 1/4 is it, but I would throw out the stock lug nuts and replace with fully threaded OPEN ones.

You need to count the turns once you put the spacer on.

Don't ask me the min. # as that will also be debated. But it's different depending on the stud size.

Somebody will chime in.

For the life of me, I don't get why the stock ones are not fully threaded & also the studs?

So fumble fingers can get them started easier?

I was asking similar, so here's a post from my regional autocross forum regarding how many threads of engagement:

Of course that doesn't take into account thread pitch, which I would assume has some effect, but he had also mentioned 5 full turns at the event as each one after that only bears like <1% of the load... seems reasonable enough.

Here's what mine looked like with ARP studs and an 18mm spacer


I didn't run it like this. Need to go back and see how many threads of engagement I actually had there, it's more than it looks in the picture, but I'm still not sure it's adequate.

Xian

Thanks guys! Yeah, I fat fingered my prior post; it should have been 5mm min but would prefer ~1/2". Doesn't sound like there's any way that 1/2" will work with the factory studs. I'm not surprised 5-6mm would be ok since that is pretty mild... guess extended studs will be on the list for later this year. Thankfully it sounds/looks like they're a pretty easy install that can be done with the front hub on the car.

One side that worked for me... the other it didn't... not sure why, froggy's best guess was that one of my hubs was aftermarket which seems pretty probable to me... so just hope that's not the case on yours and it's a pretty easy job

Xian

Good to know! I'll take a look and see. The prior owner put new hubs (LKQ, IIRC) all the way around. Hopefully I'll be able to do the job without having to pull them off the car.

Is there any issue running a 1/2" spacer that is not hub-centric and doesn't have the centering lip for the wheel? So the wheels are fully supported by the studs and not the hub... problem?

froggy47

I have run that and more. Several years autox & no failure of wheel, hub, stud, nuts or anything else. I have tried to explain to others on the forum that the wheel & hub are STUD CENTRIC Not hub centric, but there is always someone who sees that lip & gets it into his head that that is what is centering the wheel, it's not.

In fact if you put the wheel up and are strong enough to jiggle it around a bit you can tell the hole is bigger than the lip by a little bit, but hey, I gave up on those long argument threads a few years ago.

Like putting a little lube on the threads & contact surface of the nut to wheel to prevent galling. And reduce the torque spec about 10%. People who swap wheels a couple of times a month get it.

If your tire shop does it every 3 - 5 years you are probably one of those guys who reads it somewhere "clean & dry" then goes on the forum to argue.

In a word, yep it'll be fine.

Thanks.

So these are right?

Or ebay specials which are even cheaper...

What is this? I change my wheels almost weekly and have never done this.

Xian

The only studs I've ever had issues with are the ones without anti-seize.
