HI, I'd have to put my head under mine to have a look, I assume this is the prop shaft you took off?? The springs are 9 leaf which is correct as S3 have 11 leafs, the shocker appears to be on a slight angle but should be verticle, the angle of the diff is pointing down which is odd, maybe the springs are back to front??
Sorry can't help but I'll look at mine tonight
Regards
Scott
