I am having issues trying to find the proper lug bolts for this setup, i am running the OEM wheels

from doing online searches i only see 35mm ball seat bolts and 40mm ball seat bolts

EMNOTEK is recommending

10mm Spacers - Use Wheel Bolt 14 x 1.5 35mm
12mm Spacers - Use Wheel Bolt 14 x 1.5 40mm

Can anyone confirm this is ok to use?

Just buy wheel studs. Makes life so much easier.

Anyone??

Best to go 40mm with the 10mm spacers. Test them, if you hit the ABS sensor them shave 2-3mm off them.

40mm is perfect with the 12mm spacers.

Standard lugs are 27mm.

I have forged monoblocks on the car right now, so no longer the OE wheels. That being said, I count about 5.6 turns up front to remove a 27mm thread length ball seat lug bolt from a fully tightened state (5 complete turns is considered the safe minimum). That suggests that you are better off using the 40mm lug bolts with 10mm spacers. You may get lucky and they will just clear, otherwise cut them down which depending upon cost you may want to do anyway just to have the cleanest job.

OEM rear lugs are 27mm + 10mm spacers = 37mm .. 35mm is 2mm too short , get the 40mm to be safe & shave 2-3mm off if u hear a clicking noise in the back.

OEM front lugs are 27mm + 12mm spacers = 39mm .. 35mm is 4mm too short. 40mm is perfect & no need to shave .

That's what I was running with my own wheels & no issue.

^ Listen to Roswell!

u are our new wheel master now bro ...since u have so many sets of HRE

Roswell

Can u elaborate?

I always find it harder to change the studs everytime I change spacers thickness on my Japanese cars in the past as opposed to buying longer or shorter bolts on the benz.

So many sets of HRE's... Bish, you have the whole damn line-up

AMG3.2

Yeah, sure here you go.

Just buy a stud kit once and you're done with it. No shaving of bolts etc.. Plus installing wheels is SO much easier.

Carbon Dated

Excellent advice!

Roswell

I see how that stud kit works on German cars now, I thought u had to press it from behind like Japanese cars.

How safe is this method though?

I have 10 mm on the rear and use ML lug bolts straight from Dealer

would you happen to know how long is it?

I did the conversion on my MB because I didn't know what wheels I was going to run and didn't know what spacers either. I thought it would be easier to just do extended studs and buy any wheel and spacer. I don't remember the bolt length but I wish now I purchased shorter ones. I can easily put 3" spacers. It was a complete pain in the *** to do it.

I ran 2 nuts together to install them. Used loc-tite on the threads and torqued them to 100'lb I think. I haven't had any issues and I don't plan on taking them off since it sucked so bad. I'll try to take some pics tomorrow.

I think the lug bolts are a cleaner look, compared to doing a stud conversion. I use a 37mm lug bolt in the rear with my 10mm spacer. Otis inc LA has the correct bolts and can shave off a 40mm bolt to the correct 37mm length for a minimal fee.
