Hey fellow C owners...
I want this thread to be all about tuning and mods for our C's. So if anyone has done anything to their car (rims, stereo, engine mods, suspension, paint, etc) and they wish to talk about it or if they have any questions regarding hooking up their C, I want this to be the place where we can answer all your questions.
To start it off, here is everything ive done to my 2003 C230K Sports Coupe:
-RennTech cat-back exhaust
-RennTech rear decklid spoiler
-AMG pedal kit
-AMG shift ****
-Painted break calipers
-Removed "C230" and "Kompressor" from the back along with the "1.8" on the side
-Clear corner side marker lights
-17" 7 spoke alloy wheels wrapped in Michelin Pilot Sports
-Bixenon headlights
Coming soon: H&R Cup Kit suspension or RennTech suspension so if anyone has either of these or any other suspension please let me know how you like it.

Ok let the Tuning Talk hopefully begin.....

 

Did you have to reset the cpu to accept the new bixenon lights when you replaced the standard ones?
The check lights displacy on the inst. panel comes on if you add/remove any bulbs?

 

I could have sworn I joined a Mercedes forum and not a Honda Civic forum.

 

alright, well I have a question about suspension:

I have a '99 C 230 and cant decide whether to deviate from MB suspension or upgrade to an AMG C32 suspension. Has anyone gone down the AMG path on their C230? I don't really mind how "low" it looks, I just care how if feels and if the cost is worth it over, say a Koni or H&R suspension kit.

And I might as well ask if there are any other AMG upgrades, other than suspension, that would suit a w202 C230?

 

I would like to follow in Denver's footsteps but make that a C55 suspension for a 2005 c230k.

 

well get the frack out then. I dont believe I own a honda when i modded my mustang or my volvo c70 twin turbo but U must be right. Im sick of the stupid comments. i have a bug up my *** about people using this forum to start crap. dont read it then.

hey guys i have a mod question about my 03 C240....i put 18' rims on it and it rides a bit higher now so i want to drop it using H&R or Eibach springs....but on both of their websites it has a footnote saying something about Mercedes Pad System. What should i do if i want to lower my car? about 1.2"-1.4" nothing more than that.

 

Theres always RENNtech!! http://www.renntechmercedes.com/w203_pricelist.pdf

 

Bought a radio audio 10/cd from seller in germany. radio works fine but am stations are tuned in degrees of 9 instead of 1 as in U.S. tuning. anyone know how to reprogram toUS N.American settings. Otherwise have to send away. Car is 2000c230 sport.

 

Dear lord I've hit the mother load!! Many thanks to you guys, looks like my bike(s) will take the back seat on mod money this year.....NOT!
