Man, I am having a hard time making up my mind here. Living in downtown Atlanta is not far from living in the third world in terms of road conditions. No exaggeration ,every major road has poorly installed, uneven patches every 6 feet or so, manhole covers set 2 inches below grade and a host of other problems. After 3 years of enduring it, I just cannot take the 507's rough ride any more.

Soooooo, I went and test drove a 2018 Macan GTS. Cool car, and a much more forgiving ride, but I'm not ready to step down so much in acceleration. Even with a chip tune it just doesn't do it for me.

Yesterday I drove a 2018 C63S sedan - great car, would love to own and drive one, but I'm not sure even it will be that much better in terms of ride compliance in comfort. I don't want to spend that kind of dough and wind up more or less in the same place.

Last option - attempt installing KW V3 coilovers to their softest setting on the 507. I have searched the forums and there are some passing mentions of improved compliance, but most of the focus seems to be on getting the right drop or getting higher performance for spirited or track driving. Can anyone speak to the level of comfort achievable with these coilovers?

What other cars should I be considering if the newer C63 or coilovers won't achieve the objective?

If you want compliance and acceleration, a used S63 might be your best bet, followed really closely by a well configured Tesla.

Unless you are talking McLaren, compliance means decreased handling. So you'll give up some handling.

Would definitely suggest trying the KW V3's. They are a big improvement over stock in terms of ride comfort. Even if you keep the car at stock height, you will quickly realize how much "lighter" the car feels. The ride is plusher than stock ( i have my V3 dampening set moderately (more towards street comfort). I am happy with them.

Nevermind.

Accurate.

I'm on the KW V3 with DDC. I daily the car in the soft setting and have to say it feels comfortable. I can't compare to the OEM ride as I bought the car with the coilovers already installed, but I can confidently say that I have never considered the ride being too stiff or uncomfortable.

Now Hans Grenade can never run for office in the ATL. Thanks G Money for ruining my political ambitions.

I have also installed the KW DDC kit.
Coming from stock suspension to H&R springs and then KW DDC, I can personally say that the KW DDC coilovers, essentially KW V3 with electronic damping
On the Comfort mode setting, the ride is very much softer compared to stock suspension.
Sport mode is similar to stock and Sport plus mode is mainly for track.

Anything KW would ride awesome...anything KW double adjustable will be even better. I have Variant 3's on my Audi A4 Wagon and the thing rides like a dream. I have the rebound set higher than the dampening to assist with comfort and control.

this is how i've setup my shocks.

The effective adjustment range is from 0-3 turns / 0-18 clicks open.

OEM Recommended:
Front axle ___ Rebound: 1,00 turns / 6 clicks open (66% stiff) ____ Bump: 0,75 turns open (75% stiff)
Rear axle ____ Rebound: 2,00 turns / 12 clicks open (33% stiff) ___ Bump: 1,00 turns open (66% stiff)

my setting for comfort(haven't tried)
Front axle ___ Rebound: 1,25 turns (58.3% stiff) ____ Bump: 1,25 turns open (58.3% stiff) or 1,00 turns open
Rear axle ____ Rebound: 2,00 turns (33% stiff) ___ Bump: 0,75 turns open (75% stiff)

my setting
Front axle ___ Rebound: 0,75 turns (75% stiff) ____ Bump: 0,25 turns open (91.6% stiff)
Rear axle ____ Rebound: 1,50 turns (50% stiff) ___ Bump: 0,50 turns open (85% stiff)

If you are really tired of it i’ll trade you my sedan.

Mine are

Front -----> Bottom = 8 clicks from full hard / Top = 10 clicks from full hard
Rear ------> Bottom = 8 clicks from full hard / Top 9 clicks from full hard

Is more comfortable than OEM and still, the handling feels sporty.

Thanks to all of you who chimed in with details about the KWs. I think maybe its time for a second honeymoon between me and the 507.

Bump:

Quick follow up. In the same boat as OP, dailying with a 507 on DC streets.

Did you ever purchase the V3s and was there a dramatic improvement?

I've installed KW V3's on a 2009 Shelby GT500 and a 2009 BMW 650i coupe. They're okay. On the Shelby they were great. On the BMW, they lacked. Reason is this: they are not 'variable' in the sense they adjust to the road conditions. You set the compression and rebound for a particular road surface. Only on that type of surface are they any good. You change the road conditions and they cannot adjust appropriately. It's a matter of ON or OFF with KW's. Kinda depends on where you live whether they'll work for you or not.

Personally, I'd stick with OEM. I drive a '13 C63 coupe (soon to be swapped for a 2020 C63S coupe) and a Porsche Macan Turbo. Both have variable suspensions. I can't imagine going 'backwards' for a set of coilovers.

Wait
First, let's go back to the ATL part
Can we have a C63 meet up before you change cars

Pm me

Should be able to request custom spring rates and valving on a new coilover build to make your ride however you want.

I had fortune auto coilovers with 14kg/mm front and 10kg/mm rear on my BMW for a couple of years but I grew tired of it and had the valving changed and new springs at 7kg and 5kg

If acceleration is your thing and cornering not so much.... there are some nice offerings in the Dodge SVT family

Those cars ride like hovercrafts over the road and will give you plenty of ya-ya's when you mash the gas.

Texas E63

I'd try the KW's - loved them on all of my Audi builds ( Rs6 etc..)
if you need a better ride still or want a change look at the 2012 + E63's..... longer wheelbase and adj. suspension.... I also found on my car that tire choice did make a significant difference ... and running stockrims w/ 255/275's gave more sidewall and a nicer ride....

cheers

How much would you sell it for?

If you need a set of like new KW V3 coils I have a set for $2350 shipped.
