i just got a set of Gramlights DR 17x9.5 with 245/45/17 tires. As expected my fronts need spacers. I used the washer method to test how many MM spacer I need. It came out to about 6.8mm. Not worried about being precise so I figured an 8mm spacer would be a good choice.
I have searched on here for threads related to spacers and most are fairly old (at least the ones that came up). What is a good type of spacer for what I need? Any brand reccomendations? Thanks
These re are the lugs I'm using. So I already ordered the ones from eBay. I just need (want) to find a good/safe solution for the rear wheels. 10-12mm would look great but I could possibly still do an 8mm on rear and be happy.
I'm running a 5mm spacer in the rear, and I wouldn't run any more than that—for two reasons, one being the amount of thread left on the studs, regardless of how long the head of the lug nut is, and two, there isn't going to be anything left of the hub center ring for the wheel to center itself on... unless you get a spacer with a new hub center ring machined in it, and use a different hub centric ring (larger) on your wheels. I've seen some spacers like this.
The one thing you can do about thread space is use extended shank lug nuts, like these:
However, these won't go in the lug holes on my street wheels, but they do fit the lug holes on my track wheels, so it just depends. I use them on track for extra peace of mind. Otherwise, I'd get longer studs.
As an FYI - the conical type lug nuts required by nearaly all of the aftermarket wheels we use center the wheels on their own by design. Hubcentric adapters or spacers are not needed.
I did order the ones suggested earlier. How About these? Would these be a safe alternative if the ones I bought don't workout for what I'm needing/wanting? Thanks again guys
Yea those are hubcentric, but then you'd need hubcentric rings for your wheels. The hubcentricity is done with your lug nuts. You want the spacer hubcentric so it does not float around on the hub before you bolt on your wheel. The Toyota spacers are so close in size they work well and just barely move. The Mazda 59.6 bore spacers are quite a bit more money.
I thought those has the ring machined into it. Or am I looking at it wrong.
That is a ring for Mazda, It replicates the same size register for the wheel you have now. Your aftermarket wheels have a 73mm hub bore (or something like that) so they can fit any car.
You would still need hubcentric spacers on those 10mm wheel spacers to make the wheels hubcentric.
Im gona wait and see how they do with the ones from eBay that you showed me earlier. If I don't like them or they won't work for what I'm wanting ill order the others and the rings are only $24 so worth picking up just in case. Thanks for all the help on the wheels and the spacers.
I would not rely on just the lug nuts to center your wheel. I've had a ring fall off, and you'll get a shimmy at different speeds, etc. Wheels are hub centric for a reason. I even tried out stuffing two 5mm spacer on my wheels just to see how it would look, you could feel it.
You are in fact relying on tapered lug nuts to center your wheel. You certainly are not relying on a plastic ring to do it. All the ring does is hold the wheel in place while you bolt on the lug nuts. That is the whole point of the tapered seat lug nut, to keep the wheel centered.
Either method will yeild a proper result. If not there is someone wrong with how the bolt pattern was drilled on the wheels.
My track wheels are all hubcentric and my street wheels use a machined aluminum hubcentric ring, not plastic. I can tell you first hand, that the lugs alone don't perfectly center the wheel.

That is fine. I can tell you first hand that they generally do center the wheel perfectly if the wheel was drilled properly. Either way is fine. I have not run hubcentric rings on any of my track wheels. They have all been good.
My car is a bit of an extreme case, but there was definitely a pretty large difference going from no hub-centric rings to (metal) hub-centric rings on a set of 30mm bolt on spacers I had.
it went from a pretty significant steering wheel shake on the highway to much less of one.
when I ordered my next set of spacers (slip on) I just ordered them with hub-centricity built in from motorsport-tech.com. They'll machine spacers to whatever specs you want.
that being said, 8mm isn't that much spacer and most people with aftermarket wheels are hub-centric so you should be fine.

also, the hub on an FC is 59.5mm, not 60.1
In your case with that big of a spacer and wheel package I can see a hubcentric ring helping. If you are less than 10mm like we are talking about here, I think you'd be hard pressed to tell a difference. I run a 5mm 60.1 mm Toyota spacer on the front of my car, with no issues and no vibrations with no rings.
My argument is that if you are not running them now and have no ill effects, nothing will change with a thin spacer.
I got the 8mm spacers and they work. I havnt driven it at speed yet. I may order 5mm spacers to see if they will work for the front just to pull the wheel back in a bit and put the 8mm on the rear. Should give it a nice stance and function for what I need it to do.
Can anyone confirm form if I would need extended studs for the rear with 8mm spacer? I have them on but hard to tell how many threads they have to bite on.

You shouldnt need em, but it wouldnt hurt to have the extra length. I have 10mm spacers hub centric 60.1 HB and extended studs, ARP 100-7708 2.5" length, 60 shipped for the 2 front wheels.

I have 8mm I'm Gona put on the rear. I have 5mm for the front coming. If the 5mm don't make the wheels clear then I stick the 8mm back on the front and use the 5mm on the rear. I just wanted to see if I needed the extended studs.
The part number you gave me. Is that for the front or rear. Or is it the same for both? Thanks
