SONIC FREE RIDERS

For this achievement you have to finish Final Factory Expert under 5:22. Use the gear part "Power" to get thi. After the first courve jump on the higher way and stay on the right, there is the power way.
This way is the biggest shortcut in this course. Use this in every single round and you will get this achievement.
For instruction I made a video. Enjoy it and good luck!

This is easily done by using the strength-ability. There are big 2 shortcuts in Factory-Master. You can find the first shortcut at the beginning of the course. After the first curve try to stay upstairs and keep to the right. You will see a red plate.
The second shortcut is at the end of the course, after the flight. Keep to the right and you will see another red plate.

Don't forge to use the green rods to spare time.
