I'm fairly certain it's 66.6mm
got 18" monos ET47 and want to put 20mm spacers for the rear. saw some on ebay but it seems like theres so many different types. i know i need hubcentric 5x112 but whats the center hub bore? and any recommendations on what brand. Or should i be fine with picking up some off ebay
the center bore should be 66.56 and it should be hubcentric. as far as the brand, it really depends on how much you want to spend on it... Just make sure it is the correct bolt pattern/center bore and its hubcentric and you should be good,
i had purchased some spacers specific to brabus wheels and i still have it laying around... since i never owned any brabus wheels.
For 20mm, you do NOT want spacers. You want wheel adapters. Th difference between spacers and adapters is spacers simply rest on the same wheelstuds so you have to lengthen the wheel studs (or in the case here the lug bolts) This can put strain on a lug bolt that long (yes even is hub centric) so the better option s to go with an adapter that bolts to the hob with 5 lugs, then has another set of holes that the lugs will go into when fitting the wheel. (total of 10 lugs per wheel- 5 inner, 5 outer- can be different often between the 5 and 5 due to bolt head size and thread lengths) Generally a good wheel adapter from a reputable company will include the 5 inner wheel studs to mount an adapter plate to move an OEM wheel outward.
I would recommend H&R for quality of metal used.
I would not go more that 3/8" with spacers. That equates to about 9.5mm
Here, these are what you should get if you want 20mm. These are adapters, not spacers.

Vetruck what's your view on possible long term damage using a 20mm spacer on hubs, wheel bearings and suspension?
JJJ.
Bolts that long scare me. It is the same reason yougo studs and nuts rather than long bolts to torque heads in place. Long metal wire twists with force and allow for toraonal give. Studs are better, but best of all to goshort as possible for best strength and longevity.
is this the exact part and size i need?
Yes they are. They are 20mm like you asked for.
H&R part # 4056653
20mm DRA kit for Mercedes W202 (The A in DRA is for Attachment, it comes with the lugstuds that attach this adapter to the rotor hub)
