i've never had any tyre were problems on my car. even before i had the suspension channged my rear tyres would hardly wear. now after the suspension mod and 4 wheel alignment, the tyre noise has been reduced. sometimes on motorways i can only hear wind noise. star performance reduced my rear camber by 0.5 degrees to help tyre noise and reduce wear even more. so far so good. Seat supposedly run high rear camber to maximise rear end grip, but on standard set-up it wasn't very planted. thhey trade off for high camber is also high wear on the inside shoulder. it will be very difficult to get seat to admit they are in the wrong. at the end of the day you may have to pay from your own pocket to go to an indpendant firm to correct your alignmen.
