My friend has a TT roadster which has just had the rear tyres replaced. I noticed they where very badly worn on the inner half of the tyre indicating a camber problem. My question is, if as i believe its not possible to adjust the rear camber with factory tie-arms how can it be so far out? Its on standard suspension (60k miles) so its not lowering causing the camber issue. Bent upper tie-arm? Wore tie-arm bushes? Tired springs? Ideas?
