Wheel spacers and h&r springs

I’m thinking of talking the front wheels out 15mm and the rears 20mm. Are there special 5x112 spacers I need to get? I have a 2017 c43 coupe. Also has anyone with a coupe model put on the h&r lowering springs, also looking into those.

Above are NOT correct part numbers. They are for BMW and do NOT fit any Mercedes.

The correct part numbers are:
15mm DR 3055665 or 3055665SW(black)
20mm DR 4055665 or 4055665SW(black) or
20mm DRA 40556654 or 40556654SW(black).

how much does the H&R sport spring drop the car? Any issues with scraping on slow bumps, sloped driveways?

I believe around 1.2 inches I think. Living in New England is the reason I went with the 18" wheels because of potholes, I have about 2k miles on the setup and I have not had any issues with driveways or parking lot entrances being too steep. I have not scraped on anything yet. All speed-bumps are cleared. The ride is very similar to stock in all modes, but Sport+ is noticeably stiffer in my opinion. To me, the ride height is perfect and any lower it would probably be scraping often, even with all the road work going on, I have not scraped yet. A very practical ride height.

No issues as long as you take bumps and driveways slowly and at an angle.

it says the 20mm will not fit my car. The people on that website said they don’t have any 20mm for my car. Idk if it’ll still fit even though it says it won’t. And I also believe I’ll need extended bolts

Ignore "it says" and "people on that website". Spacers will certainly fit the car.

Manufacturer (H&R) says they do, even though H&R's own website sometimes is incomplete:

H&R wagon springs, stock 19” wheels, wheel stud conversion and 10mm front/15mm rear spacers:







20mm in the rear would definitely fit.

Hey bro are those 18 or 19's? I have the stock 19" rims on my 2017 coupe. Just purchased H&R VTF's. What spacers are you running and are you using a KMAC kit?

I do not recall the brand, but they are 12mm up front and 15mm in the rear. I am not using a KMAC kit yet but may do so right before I put a new set of tires on in a few months. I have been lowered for approximately 7000 miles and the tire wear looks relatively normal (unlike some of my previous lowered vehicles).

​​​​​​KMAC kit or just springs and spacers and did you use the bolts from kit or have to get different ones

Why when I select these do they say they won't fit? I bought HR VTF springs

IMO, rather than having a bunch of different length bolts for front/rear, switching to studs makes it sooo much easier to deal with spacers. Also makes sure they’re perfectly centred to eliminate any chance of vibration.

Hi Toosteeley,
please could you say me, which H&R springs do you have? Adjustable or classic 30 mm front and 30 mm rear?
