Thanks for the awesome comparison review.
Just a question regarding the DD comfort. Are you saying m3 is less harsh because it was on kW v3 or are you comparing suspensions stock to stock?
My only complaint with my 13 p31 is that it's too harsh on the bumps for DD otherwise it's pretty much a perfect sedan IMO.

P31 does not have uprated suspension like a P30. In other words, HR springs will most likely make his ride a bit stiffer if anything.

If we can find out exactly what the APX pkg is doing with the suspension then he could be right about H&R springs giving a softer ride than stock setup.
Also, I'm running Michelin PSS on stock sizes at 40-42 psi cold. Rides very harsh.

It's different in Canada. Here we get the APX package. Do a quick search on that and you will see that here they are using stiffer springs than the non p31 model. I think it's possibly p30 springs combined with 2012+ struts. Not exactly sure how the sport suspension setup is done here, never figured that out exactly.

Yup, I would of been a lot happier with the p31 US pkg because that one would have given us the softer springs, just sacrificing a bit of handling for that which would be fine.
Now I'm still curious what can be done. I don't know if APX pkg is only stiffer on springs or also has the struts tuned for that as well.
Looking to see how to soften the ride up

Well, this is a no brainer option for me!

Stock this car is already sitting low enough that sometimes I have issues getting around certain places.
So this means I can only soften the ride at the cost of making it lower? No way to keep it at stock height?
Wouldn't putting those springs on stock struts also wear them faster as the stock struts are not tuned to go with the H&R?
Also, I always thought the lower the car the more stiff it needs to be to pull that off...
Any other ideas?

welcome to the AMG family. the M156 is one of the greatest if not the greatest N/A V8's on the planet.
every dollar spent on fuel will be worth it i assure you.

The only other thing you could do is keep the car at stock height and go with a softer non-P30, non APX, spring. This'll keep the car at stock height but provide a softer ride.
Additionally, you could install some super soft all season tires to comfy up the ride.
All of this is sacrilege on a C63, but it's your ride!
The car's rear end bounces a lot more then I would like when going over dips on the freeway.
A coilover may be the route to go.

^ People run H&R springs for 10's of thousands of miles no problem.
AMG63- You could try to score a stateside non-pp suspension. That or coilovers that will allow you to adjust ride height and comfort. Or sit on a pillow?

They're really isn't a severe problem with them, per se. They aren't going to blow up or quit working, but to say that an OE strut that's meant to operate at longer range of motion, which now suddenly cannot do that, is going to last 10's of thousands of miles without degrading would simply be a false statement.
They'll start to feel a bit looser and sloppier over time, which can be hard to notice over 10k miles.
It also depends how much you've lowered your car with the springs. I installed 5mm spring pads which looked perfect to me, but some install 13mm some install 17mm which would yield in additional travel and thus slowing down the rate of wear.
Just noting what I have noticed. I'm sure others might have different experiences, but it's pretty common for OE dampers to degrade when they're paired with lowering springs. I just didn't think it would happen this quickly.

For all I know going through all the trouble to replace my suspension with that may only improve ride quality by 10%. Not sure if it's worth it.
If only someone who drove both can give us a review

What's up man! Wow, I looked over your build thread and what a monster! I've done most of what you've done minus the 625 kit. Love your plates "SUPGRL" haha. I ordered the legacy plate "GOODMPG" but it's taking forever here in cali.
So, I've got to ask what I'm sure most people wanna know, how is the power so far compared to your SC M3 and what are your plans for this C63?

So far the biggest difference is the transmission the 08-11 tranny was the downfall of the C63 and why i got rid of mine, so far with the MCT it's almost as quick as my DCT between gear shifts which i'm all about!
