Same bolt length for spacers?
I got a set of spacers from a vendor (see pics below)
1) hubcentric
2) anodized grey
3) Forged 6061 T6 Aluminum
4) anodized black bolts included
5) half the price i found elsewhere
But....
I was told the bolts sent would be longer than OEM and sized properly.
I got 10mm and 12mm but
All the bolts are the same length at 14x1.5x40
I'm curious if I need longer bolts though.
The company is closed today and I don't want to take wheels off and have to put them back on...
Anyone know if the 10 and 12mm spacers use the same bolt length?

I believe OEM shank length of the bolt is 27mm. Just add the width of the spacer to the OEM shank length. In your case, 37mm & 39mm. You can get away with a longer bolt length for the front wheels, but if the rear bolts are too long they may hit the parking brake. Anyone else feel free to correct me if I’m wrong.

Thank you
In another thread I read a member say he has to trim his bolts
But I wasn't sure how long was the max
Or how short was the minimum needed

Fwiw
I emailed Otis and they were nice
Without any more comments bc I'm not trying to bash anyone I decided to go a different route
This vendor was HALF the price. I get it, you get what you pay for.
I can wait till Monday if I need to to call the vendor. Just wondering if anyone here had info on the lug length before then

Are you planning on running the 10mm spacers on the rear. If so a 40mm stud length may be too long. You can try them and when they are torqued down turn the wheel slowly for a couple of revolutions. If you hear a ticking noise the lug bolts are too long and interfering with the parking brake mechanism. Take them out and grind or cut them down to about 37mm and you should be good to go.

Thank you.. I'd rather ask the vendor to send me proper lugs as they told me they would be appropriately sized
If I have to cut I'm guessing 1-2 rounds of the threads is what I'm looking at but I don't want to cut and then be too short.

Shank length
I too have 12 mm spacers front and 10 mm spacers rear. The lug bolt shank length should be 40 mm front and 38 mm rear. The 38 mm rear is the correct length to avoid rubbing.

I received the following response from the vendor
"Hello,
Your wheels have an original shank length of 28mm, if adding 10mm you will need 38mm. We do not carry 38mm, the next closest size are 35mm or 40mm.
The size 40mm is what is always sent when 10mm is purchased, the shank size should work for you."
Let's hope I don't have rubbing

I just shaved my bolts down on a belt sander. You can to the same thing with a Dremel. The rears are length sensitive, but you have about a 5mm cushion before they start hitting on the other side.

By what you're saying and the info I posted it shouldn't be an issue 28+10 is 38 needed but these are 40mm so they'll only be 2mm too long. We will see
