[How much change in Toe can affect handling?]

I think you car will not be that stable after changing the alignment! 

 

I guess this is a question for the track car owners.

I've not long had a 4 wheel alignment and I noticed the car felt different pretty much straight away and I'm sure the cars' predictability has lessened. The only alterations made were to the front and rear toe which have slightly altered the camber (~ 0.05') and caster (+ 0.05'-0.10') according to the alignment report.

What the car feels like now is that turn in is not quite as sharp (like I have to turn the steering wheel a touch further), and on moderate bends (steadily powering round the bend) the back feels like it is oversteering. Also straight line cruise feels a little wandery at the rear as if there is very little air in the rear tyres.

The way it drove prior to the alignment really suited my driving style, so I'm not sure what to do.


Here is my before and after 'Total Toe' settings:

Before
Front -0.22' | Rear 0.10' | Thrust Angle 0.10'

After
Front -0.01' | Rear 0.20' | Thrust Angle 0.00'


My question is... Could the small toe setting changes have caused these symptoms?

I can provide a pic of the alignment report if needed.
