Help needed - Changing gear set of differential

Hi
I want to change the gear ratio of the differential of my C63 from the original 2,82 to 3,06. With this shorter gear ratio I hope to get more dynamic in the 4th to 7th gear because I think the original ratio is to long.

The differential for the mod and the softwareupgrade are ready. Only Problem is to get the gear set with a 3,06 gear ratio. Mercedes doesn´t offer this as spare part and so I´m only able to buy a second differential with the right ratio. But I want avoid this if possible and get only a gear set.

Hope someone has an idea or better a adress where to buy.

I THINK this rear end is actually used in the dodge str8 SUV. If that's the case maybe there is an after market solutions under the grand Cherokee srt8.

Not sure how muchuck your going to have, srt rear will bolt right in and they have some performance gears you can get, if I recall corectly you'll have to get axles made but programing will be a hurtle
