W205C43AMGCoupe

I'm seeing a lot of beautiful sedans but not much love for the coupe? I'm looking for exhausts/ wheels and the coupe seems to be too new for a lot of information to be found. Any info is much appreciated, as the coupe has different characteristics over the sedan in terms of exhaust type, not sure if the suspension geometry is same as the c43 sedan/ c450 to start exploring tire fitment?

+1....can't say I've found a lot of C43 coupe mods and mine should be here in Feb.

Any trailblazers out there who have started finding mods?

Hello guys,

We have C43 Coupe getting some work done right now, Vehicle will be done by next week. Stay tuned for pictures... =)

Considering the car just came out in North America and the rest of the world, chances are that not many people have started to modify the car yet.

I have a sedan,but I'm waiting until the spring to put on my CF parts, springs, rims and tires.

I can't wait to see what this looks like!

Thanks all! Will post once I take delivery.

Vivid Racing on Dec 6th just released their tuning box for the C43 AMG Coupe. I have it on order.

The exhaust is what baffles me, from what I can tell the sedan should fit the coupe. Talk about low hanging fruit.

I would double check that. I emailed AWE tuning about their exhaust for the sedan to see if it would fit the coupe and they said the coupe and sedan have different exhaust part #s. I hope you're right and any aftermarket exhaust for the c43 sedan will also fit the coupe.

I'm right there with you. I called them and asked and they said the same thing. That is the part that is strange could be as simple as a few MMs in length that causes a part number change? In this day in age of lean manufacturing I would find that hard to believe that MB uses two different exhaust lengths in the same chassis. We will see...

Well, still no resolution on the exhaust issue, but I did just purchase the newest revision stage 1 ECU tune form AMR Performance. I emailed AMR and they said the c450 tune will work on the c43 coupe. I knew it was the same motor but wasn't sure if the 9 speed transmission would be an issue with the c450 tune. I'm going to wait until after the 500 mile break in and then send in the ECU. 476 HP here we go!

let us know how it goes. Mine shipped on Thursday, I like the Vivid racing stuff. Worked well on my 45.

I loved OE Tuning flash on my C450 and i already purchased it for my C43C. Once the car arrives I'm shipping the ECU to OE Tuning... I also kept the wheels from my C450.
For C43C i went with OEM AMG Performance Exhaust. But I had AWE on my C450 it was amazing! And I'm planing to lower the coupe…

AMR Tune is purchased, just waiting on the car to hit 500 miles for break in before I ship the ECU out. Finding any excuse I can to put miles on it!

There is no break-in period for the 43. The engine is not hand built like the 63. This was confirmed by the AMG specialist at my local dealer. He only recommended not to redline for the first 1000kms.

GEARS5

If it is recommended not to redline for first 1000kms, then 1000 kms IS the break in period.

Tej7

For the hand made engines, it is recommended not to go above 4500rpms and to try to limit the speed to 85mph. That is quite different than simply avoiding the redline. I think it's a bit of a stretch to call that a "break-in" period. Then again, the break-in period itself is a controversial subject. It's practiced meticulously by some, and not followed at all by others.

GEARS5

That depends on how much you have to "avoid the redline" by... 1000 rpm?, 2000 rpm?

Is it subjective?

Tej7

No, it's not subjective. Avoiding the redline means exactly that - avoiding redline, aka 6500rpms (for the 43).

GEARS5

The owners manual states to keep RPMs at 2/3rds of redline for the first 1000 miles for non-AMG cars (which is 4333 RPMs)... and 4500 RPM for AMG cars.

So for the 43 we can go right up to what?... 6400?

More like 5999

you guys do know that amg engines are built with so much technical oversight it is nearly identical to any engine assembled in sindelfingen or other automated facilities... techs literally cannot make mistakes due to the technology and quality control measures.

Just because an AMG engine had a single tech assigned for end to end assembly does not mean it is necessarily any better or worse than one assembled robotically. The value is in the relative performance provided through specific engine characteristics.

That said, any engine assembled (in any way) should have appropriate run-in to seat rings optimally. Theres a bit of touch to the exact execution of this, and opinions vary, but... everyone on their AMG high horse of 1 man, 1 engine.. should plan to get off once they realize there is little substitute for 100% consistency and perfection via robotic assembly.

**I'm not an AMG or mercedes representative, but my method for break-in is a series of hard acceleration, hard engine decel, in successively increasing RPM patterns... overall "break-in" can be done relatively quickly

Tej7

That was very well said I agree with your break-in method as well

sno

My break in method is "drive it like you stole it"

so far it has worked very well.... LOL
