To achievement a Perfect Pass you need to receive 4/4 blocks for the pass (Displayed on the left of your screen)
A Perfect Pass is judged on 2 things:
Being very close to the car you are passing (Almost touching sometimes)
Avoiding contact with the car you are passing
Staying on the track (Avoiding walls as well)
Abide by these 3 things and you should earn yourself a 4/4 Pass score and the achievement will be yours.
Here's a video demonstration.
