New Years Ev..... larger glasses on so bare/bear? (whatever) with me :duh:

If as you say all the mechanical issues have been tested then you are very much in my area, and this is why?..............
The condition of the geometry is very finely tuned between a balance of positions and their respected forces, the GS300 has an adjustable geometry simply because it's expected to move over time, if your cars geometry has violated the factory set-up then the dominant angle/force will permit the sort of problem you describe.
There has been many threads on this topic in 'wheels and tyres' here, this may be of comfort to you that you are not alone....
If you want to 'swat-up' click on the 'wheel-inmotion' banner below and have a gentle read at your leisure, 'IT'S FREE'
If all fails i will help you....1.2.1...... but you must keep team LOC informed with the progress..... 'no one hit wonders allowed!'
Thanks for the advice re Geometry. Have had this checked using laser system. Minor adjustment needed. However the problem is still there although I believe it's not as bad??. I am now looking at wheels and tyres. Do you think I should change the wheels round. Diagonally. or look at smaller wheels. Maybe 16" currently have the 17" with Bridgestone tyres (235/45/ZR17). or change the tyres??
