Bro, dont wory, its very common problem in vitz,u r close to solution now,for aproperiat gap,there z simple test, put the car in D, remove ur foot from paddle, if speed is ,15-20 km/hr, than u r done,its absolutely ok.in idle car will not vibrate. If tape is of gud quality,it wont distrb u for nxt 6 months.
Remembr, for any automatic trans car,dont prolong brake in D.
