I just installed these for the rear on my 2019 coupe
H&R Part# 2055665SW
Just curious to see if anyone else is running these same spacers or had any issues with them
There is soo many mixed reviews on spacers under 12mm wanted more info

Thx

I’m honestly not sure if these can fit on the car without the center but breaking off, but perhaps you may have gotten just enough clearance to pull it off, especially with original wheels sometimes one can get lucky. 10mm-12mm range doesn’t do well with our cars, cos the counterbore protrusion on our cars is 10-12mm-ish. Glad to hear it worked for you!

I have aftermarket HRE wheels. I did notice the spacer did not sit completely flush on the hub side before mounting the wheel (very minor gap) so just worried if that is the issue. But once the wheel was mounted and torqued down the gap was gone. But according to H&R's website this part should fit a 2019 C43 just want to get more assurance if anyone else here is running the same spacer over time without any issues

TModelle

Yup, your observation is correct - you’ve probably broken the center portion now. 10mm spacers don’t usually work for our cars, nor do 12mm ones.

Spacers are on my list for the Summer. What's the proper spacer to obtain for a 2019 Coupe assuming stock wheels?

p_sean

You're right! Just opened it up to see half the spacer stuck to the hub and the lip stuck inside the wheel.
I should contact H&R to let them know of this issue as their site states this fit our cars and I'm sure there is still ppl buying these things

Is anyone running 10mm spacers in the back? which brand is good? please leave any links if you have.
Thx

Those H&R spacers may work on a C63 because the C63 rotors have 6.5mm hats versus our C43 rotor hat thickness of 2.5mm, so the center bore protrusion on ours is longer than usual. Ours are 10-11mm so it’s virtually impossible to have a 10mm hub centric spacer regardless of brand.

p_sean

Anything 15mm or over you shouldn't have any issues. Are you on stock height?

I am lowered on H&R sport springs and with the 19" AMG Multispokes -For a flush look I went with 15mm front and 20mm rear (didn't have any rubbing issues)

Otis LA sells "special" 10mm (and 12mm) spacers that do fit 10mm high/tall hubs of W213 E class and I assume that W205 C43 has identical hubs. They work great on all original OEM wheels. Caution: these spacers have extremely tight snug fit on a OEM wheels (not snug on aftermarket wheels using centering rings). So once spacers are in the OEM wheels (unlike H&R spacers, these spacers must be put in the wheels first, instead of on car's hub) it is impossible to take them off with bare hands (tools are needed). Had them on my former E450.

H&R also makes "special" 10mm and 12mm: 10mm spacers p/n 20556650 for 10mm high hubs and 12mm p/n 24556650 for 11mm high hubs. However, personally I've never seen these new spacers.

BTW, standard H&R 12mm spacers, p/n 2455665 do clear 10mm high hubs. Of course if C43 has 11mm hub and not 10mm, then p/n 24556650 should be used.

I'm going with the same springs, so this is most helpful. Thanks!

TModelle

Awesome. Very good info. Thanks for sharing!

ECS Tuning is telling me they don't sell the 20mm H&R spacers for our vehicle (they recommend 12mm/15mm). Do you have H&R spacers or did you go with something else?

p_sean

I have H&R 20mm spacers

threeMBs

Do not ask them since they have no clue. Just order by part number: 4055665(SW for black) or 40556654(SW for black). For former you will need 20mm longer bolts than currently used, for later you can re-use current bolts provided they protrude through current wheels by less than 20mm (else they need to be shortened).

Thank you!

thegreyone

very wrong.

I have 10mm front & 12mm rear - supreme power spacers and I've had 0 issues


. 19'' amg oem wheels sit perfect on my C450.

See photos attached.

TModelle

Very wrong? Nothing wrong about my statement. Glad yours worked out. OP’s didn’t.

Anyway, you probably don’t know this, but yours worked out because you have a big brake kit. The rotor mounting face on your rotors are approximately 4mm thicker than stock. So that means the center bore protrusion is around 8mm on your car after the big brake kit. That’s why your spacers work. Hope you learnt something today!

See post #9. There are 10mm and 12mm spacers that do fit high/tall hubs, some upto 10mm, some upto 11mm.

TModelle

Yes there are spacers for tall hubs if you shop carefully, but the OP’s weren’t and they broke.

In my opinion 11mm provision is still not enough for a stock, unmodified car. Cars with big brake kits are a different story.

TModelle

A quick physical check on the actual car shows a protrusion of around 12mm for the centerbore protrusion. You will need a spacer with enough room for 12mm. This is stock.

If you have rotors with alloy hats like a big brake kit or C63 rotors, then those take up about 4mm more than stock, leaving you with 8mm for the spacer. In this case, you could very well fit a 10mm spacer there if you wanted. Only if modified.

These are the pictures of standard H&R 12mm spacers, p/n 2455665, and 10mm "special" spacers sold by Otis La.
As can be seen, Otis La 10mm spacers do 100% clear H&R's 12mm lip (actually the lip is 13 mm, but 1mm is "lost" due to the recess portion at base) with no gap whatsoever. I used these 10mm Otis La spacers on tall hubs of my former W213 E450 with no issues (the only caveat is that fit in MB OEM wheels is extremely snug), where I could not use H&R's 12mm. These 10mm spacers will clear C43 11mm/12mm hubs.

I run 10mm front spacers to clear the calipers on my wheels.

Doogie999

any thoughts on 5mm front and 15mm rear spacers? OEM 19" multi spoke wheels with OEM suspension. Anyone with pics with the same set up I am not sure about the 12mm and 15mm set up as I am not lowered and I don't know if it will look good. any advise for set ups with stock 19 wheel and OEM suspension would be appreciated

thanks in advance been reading a lot about this on forum but still confusing

@Alexasa I seen your post that your running 8 mm in rear and nothing in the front paired with a beefier tire and you got some good results. What exact 8 mm spacer did you get and from where sounds like a good set up since I don’t want to look like 4x4 with the stock suspension

thanks for your help
