One month ago,i found a differential for a w203 C55 AMG 2005 with her 2 drive shafts...It might sound weird or crazy,i had no problem in my differential,the reason i changed it because i got it for a good price,plus to the 05 diff cooling system,my 209 clk55 is 2004,the differential come normal and no cooling system,and later on i will be on sc swap,so my question is the car is running very well and no prob,but what do u think guys ? Will it give any improvement ? What about the gear ratio between my old differential(the stock 2004 of clk55 that comes with no cooling system) and my new one in my car now(w203 c55 2005 differential that has the cooling system)

Thanks Everyone

what do you mean cooling system? you mean the cooling fins on the back that really don't do much unless you're truly pushing your car, and even then, really dont do much?

I meant the differential that has the cooling system,as u can see in the pict i have the upgraded one

cooling finns? im guessing?
