Discrepancy

Though a proverb says, repeating the atmospheric temperature warm and cold finishes at the timing of equinoctial week, but cold weathers are lasting these days just below 10 degree celsius. Computer controlled automobile must adopt the mixture in this cold weather according to the signals from cooling liquid temp sensor, outside air temp. sensor. But my VW air-cooled 1302 Super Beetle relies just on the automatic but mechanical choke module condition with coil bi-metal heater construction that requires a bit rotating adjustment.

SUBARU BLE B4 Legacy 3L model here wears different wheels and tires from it's original design, those of BRZ has different off-set value, 55 to 48, this 7mm discrepancy causes problems, some quire strange steering reactions, feeling caught in initial rising phase, lack of linearity in action and an mission of the steering pressure, very strange on earth! This must be caused by the change of scrub points on the tread surfaces especially on the front wheels. Remember that the scrub point is very important to have been established by the factory designers and engineers, of course by many experiments by the test drivers based on their accumulated know-hows. So want I shout with loud voice to my son, never change a fundamental axle constructive geometry whatever reasons you might have! (Probably you would turn a deaf ear to me?) 
Do you think it looks better if the tire outer surface exists on the same plane of body fender by changing wheel off-set value in spite of causing incredible inconveniences? Then how about tire burst dangers touching with body wheel arch in addition to the upper inconveniences?  The importance is not the balance between tire and body vertical plane but the fundamental geometric axle construction, don't you think? Before that, you can not see your car's appearance while you are driving? You can not ignore any laws in Physics, you are not a Scientist, aren't you?
What makes you take pride while you are in the car and you are driving it?
There must be some misunderstandings? Do you have a perception that
you are not a so great person as to you feel on yourself, because it is not designed by you nor was not constructed by yourself nor was not sold only for you, just you are driving it by steering, lever and pedal action controls.
Most of a car driver might feel pleasant if his or her car was praised as good car, but an additional sentence, "Not you but this car." would makes the person feel bad, angry sometime quarreling. I don't know why, just I'm talking about the truth and the fact?
