BC7 result & son

The wheel base values of BC7 SUBARU Legacy LSi US model were measured carefully resulting the same as 2585,80mm/2580mm on both side. So, I must seek another possibility to cause left side tendency, lateral axle offset, setback or swung rear end? Much more deeper observation must be necessary at various speed, below 60km/h and above of it.

Periodical hitting noise on right frontal portion was checked by removing wheel from the hub, the balancing weight adhered on inner surface of the wheel hit on brake calliper body. By grinding a bit on the weight the problem was solved, setting must be done again also because I found out big weight 20gr on outer surface on both sides for frontal wheel. The phase setting again at 180 degree  with removing tire from the wheel must reduce the amount of balancing weight. So tiresome and complicated tasks as those would be, I must do that at any rate.

LASER(Light Amplification through Stimulated Emission of Radiation) system is invited to our professional field, my son attended some CO2 LASER advertizing lecture program few days ago. He is completely influenced by their sales opinion. He wants it instead of HONDA Civic Euro Type R, the prices are similar each other?
Remember here, healing of injured by operation area depends on the capability of the body not of the way of operation, so the healing speed and ability are fully controlled by those of the operated patient. However sophisticated method may be invited into the operation, postoperative result and healing rate do not differ so much comparing with that by conventional method.
The maker and the dealer might say so conveniently to sell the CO2 LASER system by amplifying the advantages utmost, because no fisherman does not sell fishes as they have gone bad and terribly smell?
