Doe anyone have an extra lying around they can measure for me? And what type are they, ball?

 

Approximately 45mm, 14x1.5, standard Merc seat. I think it's more of a cone, than ball. Are you trying to determine the length you need to add wheel spacers?

 

Thanks and yes. An ebay seller of spacers asked me to provide the length of the shank and type. I put the 22" G63 wheels on my G550 and I would like them to be a little further out so I am thinking that 25mm spacers would be best.

 

I still have the 25mm spacers and the correct length lugs that we spoke about. I should have the other wheels this week and will see if I need these, or can sell them to you. They are H&R spacers with what should be the correct length H&R wheel bolts. No worries if you want to go ahead and pull the trigger on the eBay ones.

 

I actually forgot about you, sorry, but I am in no hurry so let me know when you know...PM me when the time comes.

 

I plan to use stock AMG 19" wheels on the G550 until the Pirelli tires wear out. I used 25mm spacers on the front https://www.ebay.com/itm/382938378640 which bolt to the hub using either factory bolts or the black ones provided with the spacers. Since wheels now bolt to the ISO-certified hub-centric spacers (Blox brand), the factory bolts are too long so I used these
To achieve staggered look, I used 50mm spacers on the rear https://www.ebay.com/itm/383652978505. Again, these bolt to the hub using black bolts that came with spacers.I could have used factory bolts for the wheels, but since the front bolts are now chrome I use these on the rear

 

Pics? How could you use the OEM bolts with spacers? It seems they would be too short.

 

It's my opinion that the best option for spacers are those that bolt to the hub, then have threaded holes for the wheels to bolt to. Have used the kind that sandwich between the wheel and the hub with the lug bolt passing through both the wheel and the spacer on various BMW cars and SUV's and that type of spacer is prone to poor mounting, shifting and causing vibrations. I don't have pics of the actual spacers but this is what 25mm (1") front and 50mm (2") rear Bloxsport spacers look like on the G.


I don't

 

This pic from the eBay listing shows how they bolt.. factory bolts can go in the holes then the wheel bolts go to spacer as shown...

 

I got this reply from an ebay seller when I told him how long the shanks are: "Then you definitely can't do 25mm spacers. 20mm may work with 60mm bolts. 15mm would work for sure."

It will be interesting to hear what you find out when you get your other wheels!

 

Are the spacers he is selling the kind that bolt to the hub face, and then have their own threaded holes for the wheel bolts to screw into? I assume he is saying if you use the stock length bolt then you can only do a 15mm spacer, and it would be the style that the wheel bolt goes all the way through the wheel and spacer. There are more nuances to the whole set up, however. I have H&R spacers. From H&R, anything smaller than 31mm width and they are straight bolt through and require a shaft length longer than the factory shaft length plus the width of the spacer. For instance, the 23mm spacers I have (thought they were 25mm, but are actually 23mm) would require a 68mm shaft length (45mm stock shaft plus 23mm spacer width). That's what I have, and it is all from H&R. For their 31mm and up spacers, they are the style that bolt to the hub face, and then there are holes in it that you would screw the wheel bolt into. That typically requires a full-thread bolt, not the factory style that have a smooth start of the shaft and then threads at the end. That is the way it was for pre-2019 models, but I was actually able to use the factory wheel bolts in the 31mm spacers on the 2020 G63, so the extra full-thread bolts I thought I would need are actually not necessary for 31mm spacers. With 31mm and wider spacers the trick is to make sure the bolt doesn't bottom out on the hub face before securing the wheel to the spacer. That sometimes happens on pre-2019 bolts. Does all of that make sense?

 

Yes, that makes sense and you are correct in that he is basically saying that he only has bolts that are 60mm long so if the shanks of the OEM are 45mm then only 15mm spacers can be used.

Here is what he is selling: https://www.ebay.com/itm/254351385888?ul_noapp=true

 

To a point, I agree with you, but as long as the machining tolerance for the hub bore is tight enough (on both the front and back sides), using the through bolt style shouldn't present much of an issue. You should definitely be mindful when mounting through-bolt style spacers to make sure that everything is sitting very flush, and you torque in an alternating pattern in small increments. If anything is off it will indeed cause more issues with vibrations. One thing to keep in mind is that the minimum depth of load bearing thread for a 14x1.5 bolt is 12mm, so make sure the lugs are the correct length and the hub has at least 12mm screwed into it. I'd maybe go a little deeper for good measure.

H&R spacers don't have a powdercoat finish on them, so the seating surface is sitting essentially on the actual material of the spacer, not on a coating that could be a couple of mils thick (and prone to cracking off). Cheap spacers with bad machining or a coating that flakes off and changes the hub bore seating surface/diameter would definitely contribute to vibrations. I'm not saying that's what you used, I'm just putting that info out for others to consider when they are picking spacers.

 

I don't have any experience with that seller or those spacers, but he is at least aware that you need the correct bolt length in order to make the spacers work. He's offering a package of spacer and wheel bolts, so he might be limited in terms of how he can package/group things together. For something that holds my wheels to my truck I'm prone to use something I'm familiar with and know I can trust to work. I'm not bad mouthing those spacers, I just know nothing about them.
