Here's a glitch I found on PS Trophies to get achievement without beating the time:
- Complete the races in the given Time Trial
-
Wait on the final results screen - If you did not beat the time then Dashboard
(press:
- Home - Then go back in to the game).
-You should now see the pause menu over the results screen.
-Select 'Restart - Yes'
The achievement should pop when it returns to the Time Trial menu
Thank me later
