My rear shocks have sagged lots so i found a second hand set of 4 dampers and springs from an S4 but I'm thinking of putting RS4 springs on them when i fit them. I know this is not ideal but it's only my daily drive.
Is this possible and if so what are the part numbers I'll need? When i rang my local Audi dealer they said there are 3 different ones.
My car is a 1999 S4 avant 2.7T
