New C43 AMG On Order! Need Mod Recomendations

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!

Renntech has one of the best tunes.

KW springs are good.

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 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...

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...

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

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!

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.

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

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!
