Which Parts on rear suspension?

[DPG]

Who knows which spring seats i need to order in the below pick. I have a 2002 S3 and will be replacing the springs as one looks to have split. Do I need both upper and lower seats ie parts 4a + 4 + 2 + 3

Thanks for the help

I recently did mine and replaced 2,3 &4. Saves doing it again or getting half way through the job and finding one of them is fubared!

The Bilstein kit also had a set of lower seats with it. They all went in for good measure.

Cheers for the help. Think there pretty dead anyway, hopefully will sort some of the creaking at the back
