From the start Street Shoot Out (name of event) encompassed 2 competitions-Time Attack (autocross) and Drift Attack (Drift)
But thanks to many parties it was common perception that the Autocross was called SSO and Drift was called "Drift".
Time Attack was always called Time Attack, but many (mistakenly) started calling it SSO.
Since SSO has 2 disciples and as this year R3 will be solely concentrating on Time Attack , it was decided that the R3 brand be used in conjunction with the TA name.
