Based on the part number you have the 13mm spring pads A210 325 03 84.
Looks like everything is normal though.

Ingenieur

you can read the PN's?
good eye!

thanks, it does seem normal and that is what perplexes me

before 25.8"
now 26.3"

what is normal floor to lip?

I found the H&R spring TUV certification document since I am considering them. it lists everything but the rate!
interesting document: E63, front axle only, use MB diagnostics to lower the rear via the automatic leveling control system...must have a voucher and must be kept with car's records

after the springs are installed they must be inspected by an agency or certified engineer to be approved and the document must be kept in the vehicle
I want my 1/2" back! lol

Looks good
I might raise the rear a bit but that's just personal preference

Spacers?
Oem tire size?
On the threaded adjustment where are you?
Eg 50% min to max?
What is the thread length

Nice garage btw
What are your floor to fender lip measurements if you don't mind

Here's the TUV certification document for your set -up

Thanks!! No spacers and OEM wheels but 265 rears.

The fronts are maximum lowest and rears are 2 full turns from the lowest. I believe each full turn is .125".

I always measure from lowest outside rim diameter to fender lip due to tire pressure and floor slope inconsistencies but my floor is fairly flat. I'm at 22.75" on all sides from lower rim diameter to fender lip.

Thanks for the document link!

Using your method mine
F 23.7
R 24

So you are 1" lower in the front
And 1.25 in the back

If you put it at the highest how much higher?

I think the doc says the range of adjustment is
F 20 mm
R 25 mm
In the front you could raise it 0.8 or almost to oem
Rear 0.75 or 0.5 lower than oem but I think mine is 0.5 high so basically oem
If reading it correctly

This set up is a nice option
You could get 1/2" drop from stock with improved ride and comfort all with TUV CERT.

Oh I have not tried measuring the maximum height on the front. But based on the adjustment spanner, looks like it goes all the way to OEM height levels

Updated my crappy mirrors to an updated version. Got my set from Matt.

















Looks much better

Hey abcut973 did you do the install in this picture I have purchased an AMG differential unit and I am going to just swap it out with my live unit, I have checked into how Mercedes recommends doing the the swap however based on what I am seeing in this picture the only suspension that was removed was the one bolt on that lower suspension arm in the picture nothing over by the wheel which means it will take much less time to do the install which would be nice unless I am missing something in the picture.

Basically the Mercedes instructions say to disassemble the passenger side suspension to free up that axle shaft so the differential assembly can be removed if there is an easier and quicker way that is safe and effective I am all ears.

abcut973

No this is not my install. But yeah I think the key is to have a lift so you can work and access parts easily. GL

Any way of tracking down the shop in the picture? Benz wants you to basically take the passenger side suspension apart and this shop looks like it has done none of that. It's like massive amounts of work to do, they look like they disconnected one suspension bolt and then took the drive shaft off and lowered the diff out which is pretty much what I had planned on doing but if I can save time doing it the way this shop did I would like to.

abcut973

I understand. As far as I remember it is possible to do it the way that shop has done it (it's been a while since I've been underneath a C63).
If I'm not wrong that shop is ACG and the car is member's bhamg.

andrew c230k

Cool my amg diff should be here by 5pm tonight cant wait to get my hands dirty.

I'm thinking I will try it based on what I see in the pictures and if that doesn't work I guess I have to pull out the WIS and do it the benz dealership way
