Hello MBWorld!

First post as I have just ordered my 2018 C43 AMG - I am looking to do some aftermarket wheels, ride height adjustable springs and a performance chip. I wanted to know a few items form the MBWorld experts as I continue to search these forums:

• Any recommendations for 19 inch wheel fitment? I have seen 8.5" et 31 with a 245 front and 10" et 55 with a 275? - I am looking at Forgeline and BC Forged at the moment but it doesn't appear they have the secret fitment for the C43 just yet
• Looking at KW and/or H&R adjustable spring kits - Any advice on either or a recommend MB knowledgeable vendor to source either of these from?
• Looking at the Renntech tune - Any thoughts on quality of this tune or other tunes that might be superior from a dependable/performance perspective?

Thanks for your insight!

Nice congrats... good luck on the aftermarket.. why change out the adjustable ride?

Im still looking for race pads lol

Leasing? Dont forget your AMG track day!!!

Renntech has one of the best tunes.

KW springs are good.

Fixed that for you

Not changing the adjustable shocks - Just desire to lower the ride height about 3/4 of an inch - No track days for this car - I have some other toys for that

I mean when you buy a new c43, you get a free amg track day with the amg driving academy... Worth 1900

Montana107

cool! I might check that out. Thanks!

Have your dealer help you sign up after you buy.. All you really need is the vin to register... You can drive some amgs on track.. A customer of mine went last week to cota.. Drove a amg gts.. Was a blast.. 4 tracks in the US

susman@eurogermantown.com

Worse case I can help you do it. Every amg buyer should go... Its 100% worth it

I agree that it is overpriced and other companies can achieve higher peaks but Renntech is hands-down one of the best tuners for Mercedes. Any car guy can tell you that...

sean1.8t

Now I'm not saying that they aren't great, and they may very well be the best option for other models, but we're talking about the c43 specifically. So when you consider it's more expensive than the other tuners and it has lower power gains than the $300 piggy-back tunes, it would be tough to describe them as "one of the best" in regards to this car...

jonathan358

I guess you are right. They are not the best at tuning the C43!

susman@eurogermantown.com

I've had my eye on Amr.. They seem to be doing well..

Nobody makes a home unit like a cobb accessport?

A tune is all the car needs if you want that extra second on the quarter mile. I'm Eurocharged and loving it! Oh I would dump the run flats and pick up Michelin PS4S or any other non RFT tire!

Montana107

Thanks and yes run flats will be removed.

Going with the KW HAS, Michelin Pilot Sport 4S in 245 on 8.5 front and 265 on 9.5 rear with custom offsets. These along with tint, paint correction and PPF will be the first steps. Then the tune.

Still deciding between the Forgeine GA1R and the BC Forged KL12 - Most likely in a Gunmetal finish.

Where are you getting the KW HAS from? I'm under the impression that they're not available for the C43 in North America. If that has changed, that would be welcomed news.

Montana107

I e-mailed KW Automotive North America - A Technical Advisor there said he had them and could help me. I intend to contact and purchase after the holidays - I will keep you posted

Definitely remove the resonator and/or muffler! I did both and it sounds AMAZING!!

If you want to hear it feel free to ask me ?s

Cartman417

Damn the guy in that video is a huge flames lmao

Montana107

aritweets - Thanks for the video! Exhaust will be last on my list once I get familiar with the sound and determine what direction I want to go. I like what you have done here and this is a much lower cost option than a new kit.

Brixton WR3 have now made the list of wheel options... Too many options!

I think he means you're gay.

Shout out to Jack Nicholson for running that shop though
