S3 rear geometry help


Registered User
Just had the tracking checked and adjusted after fitting 18's and the rear is a little out. Can anyone diagnose the problem please (I know that I can fit adjustable tie bar's, but the car is standard so that's not the point, and I'm skint)!
NSR Toe: 1.7
NSR Camber: -2.12
OSR Toe:1.0
OSR Camber -1.29
Thrust Angle (whatever that is)! 0.03

Could it be any (or all) of the following: -
Soft springs
Worn Top Mounts
Worn tie bar bushes

Any help greatly appreciated.
