Tyre tracking settings to avoid wear??

[IS200 MCD]

My tyres are stil ripping out on the inside. The tracking is set at positive 0.3degrees (toe in) which normally should scrub the outside. However as common with rear drive cars the fronts when rolling want to toe out. thus when driving fast the tyres begin to toe out more and wear is seen on the inside.

Question is this, what toe in setting do people use to avoid this phenomenom occuring!! Will strut brace help?. Lexus garages are next to useless and lexus GB say its trial and error!! not great when the errors cost over £120.00 each tyre!!

hope you guys can help!

I think you should demand that they do your geometry! I got mine done and there is no wear on the insides of my tyres, just a bit on the outside of the front due to cornering and that is minimal
