Wheel alignment in Audi A3 1.4T

Wheel alignment in Audi A3 1.4T was checked today after 1,500 km running. Front Toe-in value Zero and Thrust angle Zero were observed in relieve. The values that should vary were not so, it's a matter for surprise, my technology in this field has been carried out after 20 years endeavor, I was really rewarded.
The room of intervention in the vehicle is not left for outsider, but it is possible to eliminate the assembly tolerance as less as possible.
This is the hidden way to make a vehicle very special custom made condition, motor power up or enforcement of specific parts are not the way, they are only pseudos.
The taste of beer must be the best this evening.
