W210 E55 AMG noisy brakes
 

Hi,
My name is Mike and i own a E55 AMG 2001 in Stockholm, Sweden.
The car is in mint condition. I have owned this car for more than 7 years now and I've always had problems with noisy brakes.
I have changed almost everything that can be changed to make this go away:
1. New Zimmerman rotors.
2. New Zimmerman pads
3. Refurbished calipers OEM.
4. New springs and shocks
My wheels are Carlsson 18", my VIN number is: WDB2102741B280462 5

The question I have: What calipers from newer models will fit bolt on? The ones I have are OEM (2 pistons I believe). Alternatively, any suggestions on how to fix the problem?
Thank you in advance,
Mike (micke@sanda.nu)
