We are going to have some deeper and long talk with my son this evening about his future life. We estimate his daily life environment is not always favorable going to different direction with his friends who are not acceptable for us, we do not recommend him to go as he is now.
Especially his intention to go faster and quicker on the public road scattering nuisances to others is not allowed however well modified his automobile might be. The basic construction of his emotional condition is too childish and selfish considering his age 27 years old.
I always say to him, "OK you may do that, but on the closed circuit only with specially modified without legal license plate at all. Of course the racing car must be carried on the truck for the purpose."

Anyway, a half converted strange car with license plate is nothing but dangerous. A circuit running automobile for competition should be specialized in that purpose only. He will know what I say if would try running on the circuit in completely different speed range, also he would realize how dangerous to run higher speed on the ordinal traffic among passenger's cars.
Probably, SUBARU BRZ would be the last present from Dad celebrating his graduation from the University and acquiring professional license. Must I propose some responsible condition prior to the gifting.
No modification is allowed and continue keeping long as it is in original condition, because the model is fully balanced in any meaning, remember as you know, any modification by replacing any parts would invite the destruction of ultimate balance fixed by the factory professional specialist, no professional layman cannot do that, just destroy a marvelous original condition.
No over-speed running about on the public traffic allowed if it might be some middle of the night.
He must know and understand well his own social position and responsibility as a professional.
