I'm new to the MB world and just got a Silver 1999 C43 AMG a couple months ago.
When I bought my C43 it was lowered and had 18" wheels on it.
I recently bought a set of Stock C43 AMG wheels and brought the car back to stock ride hight. In my opinion stock is the way to go for my C43.
I have a set of 4 OEM 2005 E55 AMG Wheels for sale if anyone is interested. Selling the wheels for $400
I also have some H&R lowering springs that fit the C43 and C32.
Here is the URL for the E55 Wheels:
