Since Tony @ WIM did the geo.settings on my car, the handling and tyre wear is now perfect, much better than when the car was brand new. Uneven tyre wear is a thing of the past. :D
I did have a IS200 Sport on a 02 plate which I bought brand new and this had perfect handling and tyre wear, never needed alignment, so I was totally shocked when I spent £30k upgrading to a IS300 only to find it drove like a pig and tyres wore down so soon!
