I thought we answered this one before? Get a decent allignment. VY2 has more than enough adjustment to eliminate uneven tyre wear. My VY2 is pretty low with no aftertermarket allignment bushes and the tyres are wearing evenly. The car doesn't get babied in any way either.
Yeah as above , i reckon a decent alignment should sort you out. And that doesn't mean go to Bob Jane .... No Way. Go to pedders or somewhere like that who will actually do the job properly, and get a 4 wheel alignment.
