I really doubt even an experience subaru tech would notice. Our cost $78.00 and now they are up to $92.00. I put it on and noticed a big dif in the wind and tram lining.
Has our car for a year (28K highway miles) and never had a problem with the paint. I tend to think it is sorta thin though. Had minor scratches that buffed out.
I think between the legacy's unique handling and AWD, people aren't used to the sensitivity.
