C7.5 rs6 lowering springs

[J555ayd]

Can anyone help me i have a 2015 rs6 . I have had an issue for a while with passenger rear sat a little higher and having a higher arch gap to rest of the wheels. I have now fitted h&r 20mm lowering springs, the front have droped significantly but same issue on the back with rear passenger sat too high. It was less noticable with the stock springs as they were all high but now with it lowered it stands out. I have serviced the level sensors thinking they may have been stuck but all is ok. The car is on drc. Springs are seated all correct aswell.
