Default Hubcentric rings.

Hey guys I got some 5mm spacers for the front wheels and they’re not hub centric. Does anybody know what size hub centric rings would be needed to fit? Is it just the center bore size? Thanks in advance. Also, the wheels are stock NA rims.

r your spacers like this ,,, mercedes is 66.6 you would need 66.6 to what ever your spacer is and the wheel side of the spacer should also be 66.6 ,,, this is a pic of a mercedes spacer 66.6 on both inter and outer

The spacers do not have a lip like that, they are completely flat. So the hub centric ring would only need to be 66.6?

Yes but then your wheel COULD be off by a mm or 2,, these shown are 66.6 inside and 66.6 outside and that is what you need,,, i will be at one of my sponsors shop maybe tomorrow i will let you know what i can get them for. if you want.

. the spacer is 15mm thick so the inside is cut in 66.6 and the outside is 66.6 so you can run stock wheels yet keep the hub centric the same inside and out so to keep your stock wheel straight,

You did not say yours to were 15mm thick, at 5mm thick it is not possible.

Does anyone have some good spacer recommendations for the front wheels then? I bought 15mm ones that look like that but do not fit over the front dust cap. The 5mm non hub centric do fit, but cause a wobble at certain speeds.

the one you got ,is it 5 x 112 if yes it should fit ,,, I think your factory wheel is not grabbing the hub enough with the 5mm so it will not be straight try to find a spacer for mercedes 5 on 112 and then you may also need longer lugs. I think this is what u need

He is now talking about 15mm spacers, not 5mm spacers.
The length of the 66.6 diameter inside is not long enough and comes up against the grease cap. Increasing the depth of the 66.6 diameter may or may not be possible, if it was increased to 15mm the 66.6 outside diameter would fall off.
The nominal bolt length should be 40mm plus the spacer thickness, you certainly need a full depth of bolt thread engagement, anything substantially less and you could strip the threads in the hub. The risk of thread stripping is increased when a so called mechanic does not use a torque wrench to tighten the bolts at the correct setting which is 80 ft.lb.

Even with just the 5mm spacer and 40mm stock lug bolts with stock wheels you WILL NOT have enough purchase in the hub and you could lose your front wheel! Do not drive the car until you get 45mm or 50mm bolts! I just did the front disk upgrade and found this out, I went with the fifty mm bolts, they go all the way through the hub, but nothing to hit on the inside up front (to long for the rear). My car is still on the lift waiting for the rear disk kit from BuyBrakes.com these will be the 300mm vented SLK500 brakes, so far conversion going well. It will require longer (30mm) bolts for the caliper Mounting but otherwise should be a easy bolt on upgrade. Will add the photo of the whole kit when my bolts arrive, with all the info.
i have not been on the road yet, I have a plain 5mm spacer and it is not hub centric, I am hoping the lug bolts center the front wheel, if not I will look for a hub centric spacer. Does anyone know that one is required up front? The rear conversion even with the wider caliper looks like it will clear the stock wheel.

Recently, when I was considering a set of TSW aftermarket rims, I found the set below of hub-centric spacer rings with new lug bolts on Amazon. For me to get nearly the same installation geometry as the OEM configuration, these spacer rings were what I needed. The description implies that the new lug bolts are longer for the required install. However, I never checked with supplier to verify that assumption.

I am using the Venum 5mm spacers, but they are for the W209 not the R170 so the bolts are to short! You need the 45-50mm bolts, if you call them they will ship with the longer lug bolts.

Good to know - Thanks. Would you recommend the 45 mm for the front and the 50 mm for the back? Or just ask for 50 mm all around?

If you were to use 5mm spacers front and back you would need to use 45mm bolts front and back, 50mm in the rear would probably hit the E-brake as has been done before.
As has been pointed out by Jim a 5mm spacer probably does not leave much, if any room for the wheel to sit on, so you would virtually have non hub centric spacers. Any spacer thicker than the amount of the hub that sticks out past the wheels centre hole without a spacer in place means the wheel is not centred by the hub. You want the wheel supported by the thickness of the wheel on the hub so spacers with lips are required. The 66.6 mm inner bore of these must be deep enough to clear the grease cap on the fronts.
I would draw up the hub, spacer, grease cap and wheel with dimensions but it is a bit too cold in the garage.☹️

well I would add the spacer width to 40 and go with that for the rear, and if not real wide you could use the same up front with no clearance problem. That would keep all Twenty bolts the same(harder to screw up) but if you were putting a really wide spacer in the back with a much smaller in the front there could be an issue and you might need front and rear sets.

Hey guys, does anyone have a good brand suggestion for 10mm spacers up front? Or what specs to look for so it clears the hub? Let me know

https://www.ezaccessory.com/. Is the site I got my 10mm hub centric spacers that I tested today, nice snug fit and you order the lug bolts you need. For the 10mm I would get 50 or 55mm. The 55 will go all the way through the hub with about 3mm sticking out. Hub centric is a must!

Are you referring to the Mercedez 10mm billet spacers? Did it fit on your SRT without modification?

I put this on a 2005 NA front hub they are the MB spacers and are hub centric, not sure if the SRT hub is the same. Stock bolts are 40mm you will need longer bolts if you add a spacer, just add the spacer width to 40mm for the right size or a plus 5mm and they will stick out about 3mm on the inside of the hub.
