I know I've seen a few brief mentions in the various coilover threads saying that the H&R coilovers will work on a 2012 C63 AMG coupe even though every place online (Including H&R's website) says they only fit the sedan.

Will it for sure fit on the coupe and work as intended with no issues? I want to be sure before buying and get a definitive answer either way.

Yes, they should work. All PFL, FL suspension is the same except the Black Series.

The coupe and sedan are the same physical design except the valving difference due to weight but even then its a not noticeable.

Shoot ECS a message and verify this wasn't just a generic answer. OR maybe email H&R?

ClemsonJeeper

Yeah that's one of the threads I looked through and saw someone saying they aren't supported. But then the post above says they are supported.

Confusion still abounds.

Wonder if anyone who actually has a coupe in this forum has actually installed them and could chime in...

Jasonoff

Not sure what confusion you're talking about. ECS said coils do not fit the coupe but springs do.

ECS tuning is reputable.

They Fit. My first set was sold to a guy who put them on in 14 coupe.

Jasonoff

Wonder why tuner shops are saying they don't?

Pretty sure BLKROKT has H&R coilovers on his coupe and is swapping to clubsports soon. But I could be wrong.

CarHopper

I think it has something to do with springs rates being slightly different between coupe/sedan. The way I see it, they (manufacturers/distributors) are just being safe so that if there is a failure they can't be blamed as they said they don't fit / they don't recommend it.

I'd believe Kriston here. And a handful of other members who really dive into suspension. They'll bolt up, and work, just be slightly out of recommended spec.

Jasonoff

Well that answers this thread then. They physically fit but may not be the best spring rate match to OEM for a coupe.

ClemsonJeeper

This is exactly the discussion I was hoping for and hearing that people have used them in coupes and they work out OK. Thanks for this!

BLKROKT

Nope. H&R springs, going to KW Clubsport.

I'm pretty sure that people here have them on coupes though. Spring rates might be different?

chrisridebike8

I stand corrected. Thanks for chiming in.

What is your intended us and how much track time are you thinking, if any? If you're only looking to lower the car you should go with just springs. If you're going for spirited canyon runs and track days then coilovers make sense.

ClemsonJeeper

No track days, just spirited daily driving. I'm getting some new 19" wheels, so wanted to lower it a bit to make it look better.

So - less about function more about form.

That being said I like the ability to be able to adjust the height to get it right where I want it which is why I was looking at these coilovers vs just springs. The cost of these were attractive too vs say something more expensive like the K&W v3...

Jasonoff

You're wasting your money then. The springs are fine.

BLKROKT

And I'll have a coupe set for sale cheap in about a month if you can wait that long. I thought they were great on both street and track.

Jasonoff

ClemsonJeeper, if you don't wait for these you're a fool. Just sayin'...
