I have installed H&R 3mm spacer to clear my rear brakes (4 pistons)

Yes, it clears the calipers now BUT it's F...ing close (about 1/2 mm)
less then a fingernail.

It does not touch the brakes, the car rolls fine

but is it safe? I mean if I push the AMG in corners and do what a AMG should
be doing.

can the branch of the wheel touch my brake and BAMMM the caliper
or the wheel fly on the highway????

Serious conscequances...

Can you help me with some info?

Thanks guys

5mm spacers?

The caliper is not going to fly off if it touchs the wheel, but do not run it that way. You have to take into account that the caliper will shift slightly when braking. Also, when the caliper is hot, your clearance may change. Measure from the outside of the tire to the lip on fender to get an idea of how wide of a spacer you can use.

I would go with a bigger spacer just to be sure. I am using a 10mm to clear my BBK and have no problems. I could probably get away with 5mm..

If I upgrade to 5mm on the rear only... the H&R are not Hubcentric
and it's only a 2mm upgrade to my 3mm = not that more clearance.

is a 10mm H&R hubcentric would be too much? wheels ET35 + 10mm = ET25
with a wheel of 265/30/19... on a 2005 CLK 55 AMG (4 pistons rear brakes)

I don't think It will be too much. I don't understand why H&R wouldn't make small sizes with a lip. . It shouldn't be a problem though, I have 10mm installed in the front with 235/35/19 and ET35. I'm waiting on my mechanic to get back to install the rear spacers, he has my bolts. I could let you know for sure in a week or two.



Edit: Sponsor RPM in Long Island might be making small size spacer hubcentric with a lip. https://mbworld.org/forums/w211-amg/...special-2.html

1. The reason that 3mm and 5mm spacers are not hubcentric is that the minimum spacer that can be build to be hubcentric is 10mm - you have to account for vehicle's hub lip.

2. If you put 5mm spacer on the rear hub (while it may be enough for what you need), you will have no hub lip to mount your wheel on. It is a realy bad idea to support the wheel's weigth with bolts only, very dangerous - do not do it.

Not true, you can have them custom made....Like the link I posted above...

You can custom make anything. Wheel's offset can also be changed (increased or reduced), but how much will it cost and is it(customization) reliable? I would not take that route. There is a reason why reputable "spacer" companies - H&R and Eibach - do not make hubcentric spacers less than 10mm - safety. I would not use anyone else's spacers on my car.

threeMBs

That is not true? They do not make spacers less than 10mm with centering lips yet. I know about that company. When and If they'll make hubcentric 5mm spacer with a lip (and I bet they can't) I may change my mind. As of now, no one can make them as such. Period.

dynomite05

I don't know how you are so certain that "NO ONE" makes them. H&R & Eibach are not the only companies out there.

Well looks like you have nothing better to do than to Google staff up. Ok. A pair of 5mm "custom" spacers is $125 from these guys and they still do not have centering lips. I also bet that their spacers do not have any safety certifications, unlike H&R or Eibach. I do not know what you do for living, but one can not make a spacer with a lip, when this spacer is less than factory hub. On most MBs, rear hub is less than 8mm. So the smallest spacer with lip that can me made for MB rear is 8mm not 5mm or 3mm. Understand?

dynomite05

I'm bored at work. I don't know about their "safety certifications" sorry. They say they offer as small as 3mm. They give you a choice of a spacer with a lip or a spacer without a lip.


Hub Centric to Vehicle Hub
This is a flat spacer that fits perfectly tight on the hub.

Hub Centric to Vehicle and Wheel Centric to Wheel
Fits hub perfectly tight and, where wheel bolts to adapter, a custom machined adapter lip fits perfectly tight into wheel's center hole. This extra measure positively influences the ride and kills vibration. Highly recommended for newer vehicles and those which will be used for towing

Well, if you're that bored, why don't you call them to see if they can make it in 3mm with a lip for MB. What you posted above I read on their web before my previous post. No where does it expicitly say that 3mm spacer has a centering lip. They just give a general "mambo-jambo". On top of that, they mostly do adapters, which is not the same a spacers. If that could be done, H&R or Eibach would be doing it. I'm sure of that.

Justed ordered H&R 10mm spacer. I wanted the little lip to make sure
it's hubcentric
