Recommendations on wheel spacers

[Shots]

Lollllll. OK well to help you sleep tonight. I installed 6mm and it's no issue for anyone else exploring this...

The math supports this.

Hey all I have a set of Fuel Cover 20x9 in a +1mm offset riding on 35x11.5. 4in BSD air suspension lift. I went with the +1 to be safe but now I want them to stick out a little more. What size spacers can I add to get to a -12 if I am understanding correctly.

also is it true the rear track is narrower than the front?

If you're current wheels is at +1, and you want them to be -12, you'd need 13 mm of offset which is roughly 1/2". Unfortunately that's probably not something you'll be able to do.

It will be too thick to safely do with slip on spacer because that will be leaving you with only 1/4" of thread engagement. That will fail, it's a matter of if not when.
It will be too thin for a bolt spacer because the stock lug studs will contact the face of the wheel. The studs being roughly 1.5" will stick out 1" beyond the face of a 1/2" spacer. That's too far for even a stock wheel, but they can use a spacer that is slightly thinner than 1.5" because they have pockets between the holes which allow the stud to fit. If your Fuel wheels don't have that pocket you'd have cut or replace the stock studs, and even with that it's a bad idea. As noted a few posts ago you want roughly 1/2" minimum thread engagement (that goes for the spacer too) so a 1/2" spacer wouldn't have room to counterbore for the nuts holding it on.
Basically, the thinnest bolt on spacer you'll find will probably be 1".

So you've got 4 options.
Push them out about 1/4" with a 6mm slip on spacer.
Push them out about 1.5" with a bolt on spacer.
Leave it as you have it
Buy new wheels.

You won't go wrong with the Bora by Motorsportech. I've had mine for five seasons for my winter setup on my 4th Gen with no issues at all.

Buy new wheels. Less hassle. One less thing to worry about.

And spacers are illegal in some states so you would have to remove them for inspection.

I did a fair amount of research when I did mine and found the best bang for my buck were the Venum 6X5.5"-77.8mm 6061 T-6 Black Anodized Aluminum W/M14x1.5 10.9 Grade Steel Hardware Hub Centric 2" Wheel Spacer's.

I would not trust an aluminum spacer, way to soft. Over time, the studs can come loose. Have to check torque frequently. I ordered the Bora wheel spacers 1.25" made out of solid steel. Pricy but way stronger. 4 weeks wait for them, they are made to order.

I know this is a super old thread, but people still read them from information. I fully get people wanting nothing to do with spacers. But a company like Bora that makes both aluminum and steel, still recommend aluminum for 90% of applications. The steel adds several pounds of unsprung weight. And let's keep in mind, our wheels are made from aluminum, and have been for decades now. You never hear anyone saying "I run steel wheels. Aluminum is just too soft". If you get hub centric, use medium thread locker, torque to spec, and check when you do a rotation, you should never see a problem with quality USA made 6061 aluminum spacers. Think of it as adding on to your aluminum wheel, not adding on to your steel hub. If aluminum is strong enough for wheels, it's strong enough for spacers. Also, there little to no difference in adding 1.5" spacer, verses adding -38mm more offset in a wheel. (+24mm wheel and 1.5" spacer= a -14mm offset) Nobody ever says a -14mm wheel adds a ton of stress on suspension. (I think most modern Ram factory wheels are +18mm offset. So an 1.5" spacer would be like a -20mm offset wheel)
Most horror stories about spacers were from cheap made, low quality, or non hub centric, or improper installation. A non hub centric spacer or wheel, puts all directional stress on the lugs. Having the wheel or spacer seated on the hub, and then lugs only having rotational presser, is as good as it gets. A hub centric steel spacer, still has the same rotational pressure on the lugs.
If an aluminum wheel can handle the stress, even with all the cutouts and pockets between the lug holes, then a spacer that has about 3/4" of solid aluminum on either side of the lugs is just as strong.
Buy quality USA made spacers. BORA, Wheel Adapters USA, or other brands made here, with lifetime warranty, and with years of experience, and hundreds of thousands of sets sold, and install correctly, you should have no problems. (I still wouldn't want weird stuff like 3" spacers with -24mm wheels! That's definitely too much leverage on your bearings and suspension parts)
