Audi S3 suspension

[WillkelsallS3]

Guys I need a new rear spring for my 2009 S3 now apparently I have aftermarket coil over dampeners on it that supposedly cost over £1000 where would I get this from??? All I know is that the stamp on the existing spring is FK100.130 or FX100.130 and they’re yellow
I’m **** with cars and this sort of thing so any help would be appreciated
